The CAA USA (also known as CAA Gear Up) Micro-RONI is a folding shoulder stock for several different popular pistols. It is shown here with a Glock 19X riding in it, with a SIG Romeo red-dot sight up top. Some shoulder stock models are even adjustable, with several positions available.
So, you ask…do we really need a folding shoulder stock for our handguns? Well, all I can say is that I am one to pretty much leave guns alone and to not try to make them into something they werenât born to be, but when I was shooting this combo, it felt really good, with the stock against my shoulder. It did stabilize the gun a bit more (as can be expected), and allowed me to use the red-dot SIG sight which couldnât be done normally with an unmodified Glock. It also helped with recoil, holding the muzzle down for follow-up shots. For another reason that this stock is really interesting – it allows the gun to be inserted and removed without tools other than your fingers. To insert, push your pistol into the opening until it clicks, then flip the lever (see photo below) up to lock it. To remove the gun, flip that same lever down, pull down a tab above the foregrip and pull the gun out.
Letâs look at the company for a bit then weâll examine the photos I took…
CAA USA, located in Pompano Beach, Florida, make a variety of shoulder stocks and accessories for shooters â both law enforcement/military and civilians.
To quote from their website:
âCAA USA is a designer, developer and distributor of modern tactical accessories, optics and handgun conversion kits targeting the Armed Forces, Law Enforcement and firearm enthusiasts across the globe.
CAA USA outfits firearms for maximum performance in any environment. Our innovative products improve your accuracy, grip, aim, and enhance balance and performance. When equipping your firearm with our range of accessories, the userâs daily operations will become fluid and consistent.â
I went over and over the website, trying to pin down just exactly what model my friend Devan loaned me to review. The more I looked and the deeper I went, the more variations I saw. I canât tell you exactly which model this stock is, except that it is a RONI version of their Micro Conversion Kit (MCK). A side note…you really need to watch the âmacaroniâ video here – it is very tongue-in-cheek and plays upon the âroniâ name.
So, it seems that the one I shot has had several items added to it, including the red dot sight, a different fore grip, a couple of side rail hand guard attachments to the rails behind the muzzle, and a light. The website offers many additional items that you can add to your stock.

Stabilizer or Stock?
It is important to note that most of the CAA shoulder stocks come in two versions…the non-tax-stamp-needed shoulder brace, and the full meal deal shoulder stock that will cost you an extra $200 or so in order to be legal. My sample has the folding stock (not the stabilizer) which makes it way too easy to hit what youâre aiming at, even at ranges beyond where you might normally aim your Glock 9mm (or any 9mm, for that matter).
So, as I found out, there are well over 15 different stocks in either stabilizer or shoulder stock guise, with all kinds of extra doo-dads you can hang off them. I only mention the âmainlineâ stocks…that doesnât include the finish variations (want an American flag on your stock? No problem!), or other items such as a Glock drum magazine option. I hear you ask âso whatâs this gonna cost me?â â¦ well, plain shoulder braces start at around $249 and go up from there to over $500 or so for folding, adjustable stocks. This is, of course, before you add any extra items or pay the tax stamp if needed. I can see where you might end up paying at least as much for the stock as you did for the pistol that goes in it, but if making a carbine out of a four-or-so-inch-barreled pistol is your thing, I say go for it…it is a pretty cool unit.
Letâs take a look at the one I had my hands on, up close…
Hereâs a close-up of the breech area. Notice the âMicro-RONIâ branding and the trigger guard âsafetyâ wings that lift up…more on those later.
The charge handle is visible behind the branding…that piece is loose (and will fall out with the latch down and no gun in there, trust me…). It is the part that âgrabsâ the Glockâs slide â you can see it just behind the gunâs extractor. This is the handle you pull to load the chamber, as the part is attached by friction the gunâs slide and the handle retracts the slide.
Hereâs the business end. You can see the side rail hand guard in place, as well as the light below the muzzle.
Another shot of the light. Youâll see, just under the side rail hand guard, a very out-of-focus tab. There is another on the other side…pull these down to release the pistol for removal.
And, what would any hinged stock be without its hinge and latch? Here you go. Just press in on the latch shown to open it.
Finally, hereâs the latch that locks the pistol in place. The website has some pretty well-done explanatory videos that show how to insert and remove your pistol. This is one phase of this stock that is really well-thought-out… no tools needed at all, and the insertion/removal is quick (once you figure it out). It took me a couple of tries but, by golly, it worked as advertised. You can see the charging handle above the opening.
So…Do You Need One?
Hereâs the question that hopefully youâll be asking yourself…do I need one of these? I might think the answer could be âyesâ if you:
- Are involved with law enforcement and have a use for the stock (if it is sanctioned for use, of course);
- Like shooting your Glock 20 10mm but want a bit more support? Try the RONI G2-10 Stab CAA Tactical Roni Stabilizer for the Glock 20 & 21.
- Need to keep the varmint population down at your homestead? Try one of these with your pistol of choice (check the website for pistol models supported). This should help keep things stabile.
- Just want to have fun on the range? These things tend to draw crowds!
If you are just looking for something different to add to your collection, a CAA Gear Up stabilizer or stock should fill that bill. I could see using one if they made it for my Springfield Armory XDM .45 compact model, but all I saw were models for Springfield 9mm and 40 calibers. (The grip safety would no doubt require some engineering to overcome, at any rate).
But…if I owned a compatible gun (there are many listed), I might consider putting one on the gun. It does change the dynamic…it just is different. I reviewed a Troy Industries âOther Firearmâ a while back. That was a short 9mm with shoulder stock and â¦ well, just check it out here. It looks like an AR, but in 9mm. It uses a stabilizing brace so it falls through the BATFâs cracks and doesnât require that tax stamp expenditure. That was one fun gun to shoot, and these CAA shoulder stocks remind me of that experience.
The Recoil Problem
The older I get, the less I like recoil. Thatâs just a fact. The guns I own tend to not have much kick â I have rifle calibers such as the .243 and .223, handguns like 9mm, .22, .38 Special and .44…Magnum. Oops…well, Iâm an unreformed, inveterate handloader and I tend to load my esteemed 629 down a bit…letâs be sensible. No need to bend anything on the gun or on me. The several deer Iâve killed with that 8-inch-plus-barreled stainless beauty really didnât know that the hard-cast 255-grain semi-wadcutter that went through their boiler room was moving at only 1100 or so feet per second – they went down anyway.
My point is that if I were to acquire a new, âlong gunâ (AR-style, in the rough sense), it would probably be for a caliber such as the .350 Legend… or 9mm. Huh? I really donât have anything to prove in the hunting field, so I might just go with something like the CAA stock or stabilizer and just add it to a pistol. With the right sight up top, it would make a dandy little close-range pest eradicator or target gun. If I were to end up with a Glock 10mm (deer-legal caliber here), Iâd think about adding the above-mentioned Glock 20 shoulder stock for under $300. Would I gain, ballistically-speaking? Nope â there is no added barrel, just the pistolsâ â but would I add to the ergonomics? You betcha! Anytime you can brace a hard-recoiling pistol against your shoulder, youâve just added to your practical accuracy and most likely added to your range, as well.
This CAA stock business just might be the lesser-expensive answer to the possible question in your mind about wanting to buy a 9mm (or other caliber) AR pistol but not being able to afford it…some of them can be pretty salty in the dollar category. If you already own a supported pistol (see the website for a list of pistols supported by the different models), you can add one of these for under $300 and then, in essence, have a pistol-caliber (conversion) carbine. You wonât get a longer barrel, but you will get better sights (either irons with a longer sight radius, a red dot, or even a scope), shoulder support, light mounting area, and other perks.
I think this little stock makes a lot of sense in some circumstances and is worth the price of admission.
