I had been wanting to add a 1911 in 9mm to my fleet. I have also been intrigued by Armscor's 22TCM cartridge. So I killed 2 birds with 1 stone and purchased this RIA Rock Ultra FS 1911 22TCM/9mm Combo.

The pistol is full-size 5". The rear sight is an LPA brand, fully click-adjustable for windage and elevation, 2 white dots. The front sight is orange fiber-optic. The package comes with a 9mm accessory barrel and dedicated recoil spring. Only one magazine is included. I purchased 2 additional magazines from Armscor. The magazines are designed to accept the 22TCM cartridge and 9mm. It's my understanding that the 22TCM will not work in standard 9mm 1911 magazines, but standard 9mm 1911 magazines will work in this gun when using 9mm. Here is a link to the specs and description:

The following link goes into better detail on the 22TCM cartridge itself:

The gun is very well-made. Tolerances are tight; the slide-to-frame fit is every bit as good as other 1911's costing 2-3 times as much. The trigger is outstanding! it has a clean, crisp, light break. The gun just has a quality feel to it. The parkerized finish is OK, durable and functional, but by no means aesthetically pleasing. The standard VZ grips are very nice, offering the right amount of grip, but not so aggressive that it hurts.

I took it to the range and fired 100 rounds of 22TCM through it. There were 2 or 3 FTE's, but I'm sure that's just part of the normal break-in. The gun functioned fine otherwise. Armscor recommends a 500-round break-in period. my other RIA 1911 .45 has run 100% with no malfunctions in over 1000 rounds. The 22TCM is an interesting concept. It is basically a 40 grain .22 cal JHP bullet in a necked-down 9mm casing. It fires at a high-velocity 2000 fps. There is virtually no recoil, but it is very loud and produces a bright muzzle flash. Accuracy was dead-nuts. I will be trying out the 9mm barrel at the range tomorrow. What I am anxious to find out is whether I will have to re-adjust the sights each time I switch from 22TCM to 9mm. I will find out tomorrow.

One could say that the 22TCM is an answer to a question that nobody asked, and I would be hard-pressed to argue otherwise. It is a novelty, for sure. However, I bought the gun basically because I wanted a 1911 in 9mm. The 22TCM is just a bonus. I am pleased with this purchase.

My 22TCM has been flawless... when I've shot it. When I let my neighbor try it out he was getting a FTE every other shot, sometimes every shot.
I'm not going to say you are limp wristing, but I will say that IMO you really need a firm extension to help that low recoil round along in getting the slide back all the way. Assuming they have the right recoil spring in it.
It's a fun gun.

Don't know much about the defensive characteristics of the .22 TCM, but I know there's substantial...Shock & Awe effect! (Flash & Loud) :gah:

Nice looking 1911! :congrats:

IMO, The failure to extract fired brass from chamber problem is caused by the necked cartage and very high pressure in the chamber.

Once some burnt power residue is built up in chamber and the fired casing expands under the pressure of firing the casing will then stick in chamber and will be a real problem. (note: may have to use a cleaning rod or something similar to get the brass out of chamber)

To clean the 22TCM chamber you may try brake cleaner ( not the best idea but it will cut the burnt power reside)or a 223 chamber brush and a slow speed drill or Hoppes #9 solvent but I don't know if it will get the residue out or not.

The 9mm will probably run just fine, but I believe there are still some kinks in the 22TCM round and barrel that needs to be worked out.

As for shooting it for defense purposes, if the chamber is mirror shinnied it should work just fine for a few mags? of ammo.

(OP) That's what I had to do when I had the 2 FTE's. I clean the barrel by using a .357 brass brush in the 9mm part of the chamber and then a .22 brass brush in the forward part of the chamber, much like cleaning an AR star chamber. I only had the 2 FTE's in 100 rounds, so we'll see what happens as the gun breaks in. I'll be shooting 9mm mostly, anyway.

This gun is strictly a range toy and will not be used for defensive purposes at all.
