Hi:
Thursday mornings are "Old Guys" shoot at my Gun Club's Firing Range.
Most of the guys that attend are "Wealthy Retired" except for me who is the one required "Poor Guy". Each week most of the guys bring a "New Toy" that they purchased. I shoot "Wheel Guns" along side of custom Model 1911s and other high custom "Bottom Feeders'.
Todays the guys insisted I shoot one of their new toys which was a custom Model 1911 type chamber in .22 TCM. I have never seen a .22 TCM cartridge or a handgun chambered for this round.
The cartridge and pistol is very, very accurate with negative recoil, but folks, the muzzle blast will curl your hair !!
The owner of the pistol told me he also has a rifle chambered for the same round.

New one to me too!
If I’ve said it once. I’ve said it a thousand times-
We need some more calibers!
That baby does move out!

I think it's still a proprietary Armscor product. I'd be a bit leery of getting invested in it before any one else starts producing products for the caliber.

That is some bodacious velocity and energy. No wonder the muzzle blast is a toenail curler from a handgun.

Oh well, what the hell.

I've wanted the Rock Island 9mm/22TCM 1911 for years now. But never see one when I have an extra $600 in my pocket. Ended up with a Kel-Tec PMR 30 that shoot 30 rounds on 22 WMR as fast as you can pull the trigger. It'll do for now I guess.

It’s not going anywhere, in fact it’s so popular we can’t make .22 TCM ammo and guns fast enough. Moreover, all of our .22TCM 1911s come with a 9mm barrel and recoil spring, giving you the best of both worlds.

It must be noted that the .22 TCM is not a SAAMI (Sporting Arms and Ammunition Institute) approved cartridge. This does not mean it is unsafe. Initially, all new wildcat cartridges are unapproved by SAAMI. What it means is that as of right now, SAAMI has not established manufacturing specifications or tolerances for the .22 TCM. So, don’t expect to see ammunition or handloading data available from American-based companies; though .22TCM powder and reloading dies are available from Hornady.

Try shooting a 22 Hornet out of a 10" Contender without hearing protection.
Bet you don't do it twice.

I have an RIA 22TCM/9mm. One fun gun! Really gets attention at indoor ranges when a 1911 sounds like a short barreled 357 mag going off.

Ok, I'll ask.... WHY?
What does this round offer and what's its purpose?

Why?
Why not?

It offers a 40 grain bullet that travels at 2000fps, something the .22 Remington Jet never quite achieved and it makes a lot of noise, it makes a big fire ball, and it's a blast to shoot.

It’s purpose is the same as all ammo, it pokes holes in things, it just gets to the target way faster than other handgun rounds.

I had the RIA 22TCM/9MM, 1911 Commander version. It was reliable and accurate in either caliber. The 22TCM clocked thru my chronograph at 1915 fps for a 10 shot average. My KelTek PMR#30 clocked around 1500fps. I did experiment with reloading the TCM, but without solid info I was never able to match the factory ammo. A shooting friend has the full size 1911 and the rifle. I consider the rifle a waste of money and ammo. A rifle in .223 is less expensive to shoot and with better accuracy.
I sold my pistol because no other manufacturer of firearms or AMMO stepped up to the plate with guns or ammo. As far as what's it good for, tons of fun at the range. Very low recoil and lots of muzzel flash.

I got a 1911 commander in a trade about a year and s half ago and shot it quite a bit. Very entertaining gun to shoot and really accurate. I ended up trading it for something I wanted more (K38 Masterpiece), but I’ve been looking for another here and there. I wish RIA would make a .22WMRF/.22TCM combo now that they are putting out the .22 mag in a 1911 platform, but there are probably some technical issues that would make it too expensive to produce.

I can not recall how many years I have had my .22 Tuason Craig Micromagnum pistol
I got it before 22TCM loading dies were readily available. I was on a waiting list with Hornady for several months before they arrived. It gave me time to gather up projectiles from various manufacturers to start load development with.

The cartridge is a hoot to shoot. It is very accurate and very flat shooting and as already mentioned it is an attention-getter in the muzzle blast department. Fred Craig did a good job with this one.

My TCM has never had the 9MM barrel installed, but then I already own other 9MM double-stacks.

I wish that RIA had come out with a 6" long slide variation. When I spoke to RIA's CEO Martin Tuason out at SHOT a few years ago he told me a long slide was not in the near future for the auto loaders.

I think that the factory load would do well with a little extra barrel

Hand loading components are readily available and reasonably priced.

One of the misconceptions about the 22TCM cartridge is that the 9MM Parabellum is the parent casing and can be used for case forming. While these two cartridges do share a case head, the 22TCM was actually created from the 556 NATO case. As you can see here there is no way that the 22TCM could be formed from a 9MM Parabellum.
The 22TCM provides ballistics similar to the FN 5.7x28 round in a package that can function in a 1911

For me it is also the enjoyment of load development

As well as being a lot cheaper to shoot and (supposedly) easier to reload. AND the 1911 platform is way better looking than that striker fired plastic gun.

I have found the 22 TCM to blast to reload for. Lil Gun, H110 and LongShot all provide plenty of uumfff to easily get to factory velocity with handloads. And Speer and Hornady 45 gr bullets feed well and produce great accuracy.

The only difference between men and boys is the price of their toys.
