KelTec CP33: Pistol With a Twist

Best KelTec CP33 Accessories KelTec CP33 Pistol
KelTec CP33

Before we delve into the accessories we’ll take a closer look at the KelTec CP33. 

The Keltec CP33 was introduced at SHOT Show 2019, and it has caught the attention of many since then. It’s a competition pistol, hence the name CP. With a unique quad-stack magazine, it holds 33 rounds in a flush-fit fashion. 

In addition, the CP33 was designed after the CMR-30 rimfire carbine. As a compressed version, you get just as much fun, but at a smaller profile. It also has a Picatinny rail on top and an M-Lok slot under the barrel. Both of which welcomes just about any accessory you might need.

This large-frame pistol features a threaded barrel and fiber optic sights. The charging handle is at the back, much like an AR-15. One thing that looks a bit out of context though is the heel magazine release. Still, not a total deal-breaker. 

Yes, the CP33 is a pistol but one that can be used as a powerful personal defense weapon. It’s the closest you get to an H&K MP7, but at less than half the price. While the MP7 costs around $1,700, the CP33 has an MSRP of only $550.

KelTec CP33 Specs

Caliber.22 LR
OperationStraight blowback
Mode of fireSemi-automatic
Weight (unloaded)1.5 pounds
Height6 inches
Overall length10.6 inches
Barrel length5.5 inches
Barrel threads1/2-18 TPI
Twist rate1 in 14 inches
Magazine capacity33 rounds

As a rimfire .22 LR pistol, the CP33 holds ammo of 40+ grains. As long as you load it with the right ammo, you shouldn’t have any feeding problems. You also get an extra magazine out of the box so you have 66 rounds with you right away. Therefore, that means less interruption as you send the plate and paper targets away. 

One great feature of the CP33 is that it gives confidence to anyone willing to shoot it. It is only 10.6 inches long, weighing 1.5 pounds unloaded. It’s small and light, and with the low recoil of the .22LR, you get a gun that’s just a joy to shoot. Even kids love it, as we can see with Autumn’s Armory below.

It’s KelTec— which can be enough reason for some to dismiss it right away. However, the CP33 is one that leaves a lot of room for the imagination. Put in a brace and it will be the size of a carbine. Mount an optic and it’s just as good for plinking. 

The thing is, it can offer much so more when paired with the right accessories. In fact, it brought about the conception of the new cheek pistol concept. 

What’s a Cheek Pistol?

The cheek pistol concept is a fresh take on handling large frame pistols like the KelTec CP33. It was invented by Rhett Neumayer, an outside-the-box thinker. He is, as Lucky Gunner called him, “The Tactical Mad Scientist.”

As the name says, this technique involves supporting the receiver’s end with your cheek. Your weak hand acts as another support near the front of your red dot. However, this position looks weird at first, but what you get is exceptional shooting performance. You might be shooting a pistol, but your bullets will fly like they’re coming from a full-size rifle.

Turning your CP33 into a dedicated cheek pistol needs some tweaks and experimentation. Therefore, expect to throw in some effort. So, grab the spare accessories lying around to see what fits. After all, customizing a gun is just as fun as shooting it.

Now let’s get into the details of the best KelTec CP33 accessories out there.

Great finds are hard to come by when there’s just so much to choose from. That said, we did some digging to see what makes the CP33 tick. So read on and see what fits your CP33 upgrade. 

Muzzle Device

A suppressor or a compensator will steady the muzzle and help you to hit those targets. A flash hider will also lessen the blast of the .22LR. Expect a dirtier unit though with the can on. As with everything, it’s always a good idea to service a gun regularly—and the CP33 is no different. 

Yankee Hill Stinger .22LR Suppressor

The Yankee Hill Stinger 22 is a 5.3-inch suppressor .22LR for guns like the KelTec CP33. It is threaded 1/2×28 so it sits perfectly on the muzzle. At 5.5 inches, it has the same length as the barrel itself. It is pretty lightweight, so installing it will only add six ounces to the total weight. 

This can is made of aircraft stainless steel. It’s full-auto rated, making durability the least of your problem. One unique feature it has is the K-baffle design which lessens the inevitable buildup inside when using muzzle devices. This system also makes cleaning and taking it apart a lot easier. There are seven of these funnel-like baffles, numbered for easier identification. Just line them up and you’re good to go. 

From the box, the suppressor includes a take-down tool to take the end cap off for cleaning. There’s also a nylon rod to push the baffles out without scratching. Below is a video showing how easy it is to assemble and disassemble.

Once installed, the compact profile of the Yankee Hill Stinger 22 matches well with the CP33. The anodized matte black finish makes it a neat extension of the muzzle. 

With the Yankee Hill Stinger 22 in place, the CP33 becomes more stable. It also provides room for a supporting hand. One big plus is that it comes at an affordable price. For those who don’t like to wear hearing protection, adding it would mean doing your ears a favor. 

Big but here is legality. Some states do not allow suppressors. In that case, better look for a compensator which is also much cheaper.

  • K-baffle design
  • Easy to disassemble and clean
  • Adds barrel length
  • Noise reduction
  • Affordable price
  • Not legal to own in some states

TandemKross “Game Changer” Compensator for .22LR

Best KelTec CP33 Accessories TandemKross "Game Changer" Compensator for .22LR

If you’re not a fan of suppressors, then add the TandemKross Game Changer compensator. Aside from adding a bit of length to the CP33, it also lessens muzzle rise. Not that you get that a lot from the .22LR. Still, it’s a quality add-on you can easily get without hurting your pocket. 

This compensator is made of T6061 aluminum with clear hard coat anodizing. It’s 1.75 inches long and weighs only 1.23 ounces. The vents are designed with an upward position to counter recoil. 

We might not get a lot of recoil with the CP33 but adding this on the muzzle makes staying on target easier. Also, follow-up shots are faster. Again, remember to clean it though, as the buildup is the ultimate boon of every muzzle device. 

The video below from TandemKross might help you on how to maintain your compensator. They also covered the science behind some common cleaning methods and the risk they may have.

There isn’t much more to say about the TandemKross Game Changer compensator. It does what it was made for—and it does it effectively. It’s a trusty compensator, which is a real treat for the threaded barrel of the CP33. 

It’s nice and glossy, but the price is another thing that catches the eyes of gun shooters. If you don’t want a bulky muzzle device for your KelTec CP33, then this is for you.

  • Great design
  • Reduces muzzle flip
  • Glossy finish
  • Inexpensive
  • Can be hard to clean


The CP33 has a 9-inch sight radius, with adjustable iron sights that are remarkably bright. The front is a green fiber while the rear sight sports a red one. Some like them as they are, which is good. 

However, if you want to maximize the shooting ability of your CP33, a red dot makes it unstoppable. With the small profile of this gun, an optic with a higher mount would be ideal to use. 

Holosun HS403C Solar Power Micro Red Dot Sight

Holosun HS403C Solar Power Micro Red Dot Sight

The Holosun HS403C is a solar-powered red dot sight. It has a battery backup for when the sun isn’t out. 

You’ll most likely use your KelTec CP33 outside during daylight hours, so the solar-power option is a huge plus. The solar auto-on mode easily adjusts the dot brightness depending on the light it gets. So when you’re at the range, you can just start the fun the moment you pick up the CP33. 

It comes with a lithium battery that lasts up to 50,000 hours. They put a lot of thought into this one, especially with the power-saving features. Meanwhile, some users complain about the adjustment buttons not working in manual mode. 

This red dot is waterproof and is housed in high-strength aluminum. It measures 2.36 x 1.57 x 2.95 inches, weighing 4.16 ounces. The lens is clear and you can easily see the unmistakable 2 MOA dot. The tall riser complements the CP33 well and allows you to use the irons if you like.

The Holosun HS403C is an impressive red dot sight with floods of 5-star reviews online. Some have been using it for years without any problem. It’s a great value optic that suits the CP33 well. If this is a name you haven’t heard of, then you’re missing out on one of the most affordable options you have for a red dot sight.

  • Multiple power system
  • Solar auto-on feature
  • Holds zero well
  • Affordable
  • Manual mode adjustment can be tricky

Sig Sauer SOR52001 Romeo5 Red Dot Sight

The Sig Sauer Romeo5 red dot looks very similar to the Holosun HS403C, minus the solar panel on top. This is a more affordable option that costs around $120 (or even below $100) depending on where you buy it. 

The first thing you’ll notice about this red dot is the clear gas quality. Dot size is 2 MOA, with unlimited eye relief. It runs on a CR2032 battery (included) that can run for about 50,000+ hours. While it does not have the solar auto-on feature, it has a Motion Activated Illumination (MOTAC) feature. Not only does it save battery life but it also makes it very convenient to use. 

This red dot is small and compact. It weighs only 5.10 ounces, perfect for the CP33. The riser mount makes it easy to co-witness with the front sight. It’s not totally parallax-free but the slight shift is easily negligible. After some abuse, it holds zero just as well as when you first put it on. Also, it has an impressive 10 illumination settings, two of which are for night vision.

The Sig Romeo5 red dot is one of the best red dot sights at the budget end. It’s really great that you can maintain your grip and position with the shake awake feature. The lenses are superb and the dot is crisp. Most of us may have grabbed it for the price, but it’s the quality that keeps it on the rails of our guns.

  • Great glass quality
  • Motion Activated Illumination (MOTAC)
  • Small and compact
  • Holds zero well
  • Very affordable
  • Slight parallax


Tactical lights are always a good addition to any gun. The CP33 is a versatile pistol. You can use it for about anything, including close-quarter encounters. In such scenarios, good light isn’t guaranteed so it’s always a great idea to bring one with you. It will help with target identification. It, also, adds a bit of safety helping you make sure you see what you are shooting at.

Whether you’ll put it at 6 o’clock or 12 o’clock depends on how you’ll use your CP33. Put it below the barrel if it’s going to be a cheek pistol. But if it’s for more conventional use, 12 o’clock position is the way to go. 

Olight Odin Mini Rechargeable Tactical Flashlight

If you want a rechargeable flashlight, then the Olight Odin Mini is for you. This is a more compact version of the full-size Odin model that is just as great. It comes in two colors: black and desert tan.

The Odin Mini features a 1250-lumen white LED. It is housed in aluminum alloy, with an overall weight of 6.21 ounces. It is powered by a rechargeable lithium battery that’s also included in the box. 

The runtime can be as long as 5 hours. However, it becomes much much shorter when used at constant max brightness. It has a low power vibration alert to let you know when it’s running out of power. In addition, it features magnetic charging. 

This light is compatible with the MLOK and Picatinny rails of the KelTec CP33. It has a rotate-to-lock for easier installation. The tail switch allows you to easily turn it on and off once installed. This tail is removable if you want to use it as a handheld flashlight. To change the brightness settings, just press the tail cap and you’ll see the change in intensity.

The Olight Odin Mini has a lot of well-thought features for any shooting needs. It has great construction, great size, and is very easy to use —perfect for the CP33. The rechargeable feature is also very economical. Now if you want a light which you can use handheld as well, then this is a great choice.

  • Compact and low profile
  • Tail switch
  • Magnetic charging
  • Low power vibration alert
  • Low battery life at full brightness

Streamlight TLR-8G

Streamlight products will always be part of any lights and/or lasers list. And for the CP33, a TLR-8G at the 6 o’clock position will give you many advantages. 

The TLR-8G provides illumination while also allowing quick target acquisition. The 500 lumens white LED is all you’ll ever need in low-light situations. Meanwhile, the green laser is just as high-quality. It’s accurate and very visible even in the daytime.

This laser light runs on a CR123A lithium battery. Run time is 1.5 hours but, of course, using it in laser-only or light-only mode will prolong it. Also, it has a “safe off” feature to help conserve battery.

It has durable aluminum construction. Installing it is very easy and you don’t need any tools whatsoever. The clamp system lets you attach it quickly and if you need to remove it, it’s just as easy to detach. This compact combo only weighs 2.64 ounces and is 2.15 inches long.

The Streamlight TLR-8G is a quality laser-light combo you can add to the CP33. It offers an exceptional tactical advantage, but at an equally higher price. Still, it’s a combo, plus green lasers don’t really come cheap. If you’re willing to spend on a reliable product, then this is for you.

  • Laser-light combo
  • Small and compact
  • Durable and water-resistant
  • Easy to install/clamp
  • Ambidextrous controls
  • Safe off feature
  • Expensive

Brace and Adapter

A brace and adapter make the perfect pair if you want to bring more stability to the CP33. Use it against the shoulder and you get a third point of contact. If you want to shoot one-handed, then get a stabilizing brace. Whatever you choose, better accuracy is almost always guaranteed with additional support. 

SB Tactical FS1913 Pistol Brace

One of the most common attachments on the CP33 is the SB Tactical Pistol Brace. Since this pistol doesn’t have an M1913 at the rear, you have to get the Rehv Arms adapter for the CP33

This is a side-folding brace that folds on the left side. It is made of polymer and weighs only 10 ounces. You can also get it in aluminum if you like one. Though it comes at a higher price, the latter doesn’t have that flimsiness you feel on the polymer version. It measures 9.6×1.2 inches, just the right size for the pistol. 

Here’s how you install it:

Pretty much everyone knows about the SB Tactical brace. I mean, who wouldn’t when it made the party more fun for the SBRs? Brace or stock, whatever you call it, it’s a great addition to the CP33 as long as gun stability is concerned. Also, it’s widely available so you can easily get one yourself.

  • Makes the gun more stable
  • Easy to install
  • Easy to fold
  • Wide availability
  • A bit flimsy (polymer)

FarrowTech Telescoping Brace Adapter with A3 SteadyBrace

FarrowTech has a brace and adapter specifically for the CP33. I must say, the SteadyBrace is a very fine-looking accessory that adds great value to your gun. The carbon fiber rods look rock-solid and, overall, it’s very lightweight at only 2 ounces. The length of pull is not more than 13.5 inches. 

The aesthetic is guaranteed on this brace, but it’s more than just eye candy. Once installed, this brace works well with all the other parts of the CP33. It doesn’t get in the way of the bolt release and everything else also function as intended. 

It is collapsible, which I also like. That makes it very easy to store after a shooting session. It’s snag-free and doesn’t shake, unlike other braces. 

You can get the SteadyBrace in either polymer or aluminum. FarrowTech also has the Tailhook option if you want a more circular end of the brace. Below is a step by step installation video you can follow:

FarrowTech sets the bar high in the adapter and brace category. The SteadyBrace is a well-designed accessory that makes the KelTec CP33 even more exciting. The only thing that many are not excited about is the price. The adaptor itself costs $175. It becomes $225.00 when you buy it with the polymer SteadyBrace and $255.00 with the aluminum option. 

As they say, you can’t have your cake and eat it too. A well-constructed accessory must come at a price. So if you have the money, look no further than the FarrowTech brace.

  • Collapsible
  • Lightweight
  • Excellent functionality
  • Great aesthetic
  • Premium price


If you attached a brace to your CP33, then adding a sling would be the next step. It makes the gun easier to manage and keeps it constantly close to you at the same time. Adding one is surprisingly challenging though. Options are limited, especially for single-point slings. 

You can always improvise, but it doesn’t hurt to buy one with good functionality. Be ready to get some QD attachments though since most slings (if not all) don’t come with those.  

Edgar Sherman Design ESD Sling

ESD Sling from Edgar Sherman Design

The Edgar Sherman Design (ESD) Sling has a minimalist design that gets the job done. It is only 1-inch wide, so it’s small and slim rather than bulky. With about 10 different colors to choose from, it brings out more character to the CP33. 

This sling gives a lot of room for adjustments. First is the rear adjustment and the other for changing the length. It uses an elastic pull tab to easily shorten or lengthen the sling. What’s great is that it’s self-stowing. With that, you don’t have to worry about any extra length of strap getting in the way. 

The quick-adjust system of the ESD Sling puts it ahead of other sling designs. It’s awesome as it is, but having a padded option will also be great. Other than that, the slim cut of the sling carries the CP33 well and that’s all that matters.

  • Quick adjustment
  • Slim and not bulky
  • Self-stowing
  • Simple and easy to use
  • Many color options
  • Not padded

Want Even More Accessories?

If you are considering something for the grip, then try the GripOn Textured Rubber Grip Wrap. It gives you that rubberized texture on the surface for a more comfortable grip. Another one you can get is the TALON Grips for Kel-Tec CP33. With great ergonomics, you have more control of the CP33. 

With the 33-round capacity of this pistol, it seems like you almost wouldn’t need another magazine. What you’ll find cumbersome though is loading it, so a speed loader will be of help. Take a look at the Ludex Speed Loader that’s customized for the quad-stack design of the CP33.


Great accessories can bring out the extraordinary in ordinary guns like the KelTec CP33. While it’s a unique-looking fellow to begin with, spicing it up with the right add-ons brings out twice the fun. So make use of those rails and prepare to take over the range. 

As for me, I’d like to see the Game Changer compensator and Holosun red dot on my CP33. It can do without a light on since it won’t sit on my bedside table. What I will not miss on it though is the FarrowTech SteadyBrace.
