If you’ve never shot a pistol chambered in the original 22 TCM, you are missing out. Pushing a tiny bullet at nearly 2,000 FPS out of a 1911 style platform resulted in a feeling that was similar to shooting a very noisy airsoft gun. To put it mildly, it was rad. But the original 22 TCM was too long to function in most modern semi-autos. Until now, because Armscor has just launched the 22 TCM 9R round, and a set of Glock conversion barrels for it!
So what’s the difference? Simple, really. Using the same brass, Armscor shortened the length of the projectile, bringing to the same OAL as a standard 9mm round. What that means is that now using one of the conversion barrels for either a G17 or a G19, you can have the maximum amount of fun you’re allowed to have with a handgun.

It’s difficult to explain, but imagine shooting a .22 LR that sounds a 9mm, or imagine shooting a 9mm that has basically no recoil. That’s a 22 TCM 9R, it’s just unbelievable fun to shoot such a flat shooting round, and now you can do it out of a Glock with these conversion barrels. The barrels are priced at the extremely affordable level of $140, and come with everything you need to get started shooting, except for ammo. There’s the barrel, a guide rod, and a recoil spring, which is specifically designed for the .22 TCM 9R round, guaranteeing optimal function.
There are some practical uses for this cartridge as well – it’s great for small game and varmints, and it would make a good “in-between” round for a new shooter who’s ready to graduate from a .22, but maybe isn’t ready for a full on 9mm yet. No matter what though, the first time you drop the striker on one of these rounds, you’re going to be grinning from ear to ear.

I have a 9mm and 357sig conversion barrel for my 3rd gen g22. Maybe a 22tcm barrel as well?
Dwight, Rock Island Armory has yet to release a G22/G31 conversion in 22TCM9R. This might be due to the fact that a conversion barrel for a .40 based pistol may be too heavy overall for proper function. It was a fine balancing act with the weight of the 9mm-22TCM9R conversion barrels themselves and a long time in the making!
Can you just order extra guide rode & spring or just another spring? Thanks Frank Castano
We don’t have that option in stock at this time, sorry.
When are you going to have the barrels in stock for the g19 models. My wife ordered back in November and we have yet to see anything. Are they even still available?
