22 TCM Barrel Swap into 1911?




Question is: could a 22 TCM barrel be swapped into a full-size single stack RIA 9mm 1911?
I'm guess in the magazine would be the same.
If it could work, I wonder if Armscor would sell just the barrel?

From what I've read the magazine for the .22 TCM isn't dimensionally the same as a standard P-18 mag and one forum member mentioned having to make certain that 9mm rounds were seated far enough back to ensure proper feeding. I could be mistaken, perhaps a modification might be in order. I just don't know since it's such a new cartridge.

That is a interesting thought. Watched some guys over the weekend try to tweak their 22TCM pistol to handle the 38super in adding a third barrel option to setup. Main issue was getting the new/2nd extractor to work.

I thought the Micro Mag pistol had a staggered magazine for both the .22TCM and 9mm rounds? Therefore, a fatter grip. Or am I mistaken?

Mag is a 38 super hicap.

I would expect no problems fitting 22TCM barrel to a single stack frame set up for an unramped 9mm barrel.

I've only got 200 rounds 9mm through my 22TCM, but the installed extractor (22TCM) worked flawlessly with the 9mm.

the 22 tcm round has a cartridge OAL that is 1.265 inch
a 9mm round is COAL of 1.150

The tcm round will only feed and function in the P18 38 super mag and it (the p18 mag)will also conveniently hold the 9mm in the tcm with 9mm barrel.

so to answer the OP's question ,No the 22 tcm barrel will not work on a single stack 9mm the rounds won't fit in the mag

the frame of the tcm is a A2 hi capacity .
the pistol comes with a light weight recoil spring for the 22 barrel and a heavier spring for the 9mm barrel
and the current production tcm pistols only come with 1 extractorr that works for both the 22tcm and 9mm as the rims are almost the same
a 22 tcm rim is .375 diameter and a 9mm rim is .390

the 22 tcm case is new brass from armscor , but originally it was a wildcat cartridge made from a .223 remington case that was cut down and renecked

Information is appreciated. I've been wondering if the mag was proprietary to the round or if it used a like mag with another cartridge. Guess that answers my question. I knew the COAL is too long for standard 9mm mags.

I've read about the genesis of the .22 TCM, fascinating little round (to me) and the man behind designing it, a Mr. Fred Craig. Pretty damn interesting (once again, if you're me) read. I also like the .22 Mig rifle he makes-in theory-and that Armscor manufactures as well. Pretty cool to see a guys innovations take shape and then hit the market. If you look at his website you can see he's had a bit o' influence at RIA as well http://atomitronx.com/products.html

No, per Ivan, the TCM barrel will not work in a single stack. I wanted to do the same thing.

The frame is different,look at the rear, looks something like a Para HI CAP. frame, but different also.
check out the Fred Craig web site. he talks about it some.

OK, so a 9mm is out. What about a RIA 38 Super? I happen to have one of each in my gunroom right now. I'll post an answer to that one in a bit...

Well, the 22TCM ammo seems to fit perfectly in my 38 Super mag.

Looking the two guns over I see another problem with swapping. It looks like you'd have to swap the slides as well as the barrels.

Gimme a minute...

Figured it'd be related to the slide dimensions.

The slide starts to fit but the ejector is slightly different. From the side it's the same shape but looking lengthwise it's wider and doesn't clear the channel in the slide. It looks like the 22TCM ejector would work for the 38Super which would allow the swap but I'm not going to be trying it anytime soon. I took some pictures but you really can't tell much from them. If I can get better ones later I will try to post them. Sorry for stringing together 3 posts for this, I probably should have waited and made a single post.

If you get the Atomotronx Micro Mag, Fred Craig states that you can use a Para double-stack 9mm, modified, for the TCM .22.

38Super uses the same Extractor as the 9mm so, there shouldn't be a problem.

looking at the barrel, i don't see why you couldn't throw the complete slide onto a 9mm single stack frame that isn't cut for a ramped barrel.

Look forward to the answer. I have a 38 super colt that the tcm would be great in.

Thanks for your help.

Just a quick query. What's the build quality like overall? Interesting piece, almost want one just to have it. Though my budget won't allow for it for at least another year or two and there are other guns I want more, so you'd best make it two to three years. I would like to get into the IDPA/ISPC scene eventually even it'll be a bit of a drive after school. Be a good platform if it could be easily turned into a .38 Super.

Also, getting into gunsmithing it'd be fun to make one in a Commander length, though to be honest my imagination has always run a little wild and I keep thinking a CCO sized 10mm would be a wild little beast to cook up as well...maybe a carry comp style, you get the idea, big dreams from an itty-bitty mind. I even had the question of a .38 Super conversion for the .22 TCM the minute I read about it, just glad to see I'm not the only one. It's why I'm so in love with the 1911. I can look at one and see a dozen-dozen possibilities before me instead of just another mass produced, cookie-cutter designed firearm.

I ordered a RIA 38 super today. As soon as I get it I will updated every one. I hope it works but if it don't I guess I will have another 1911.

I have pics posted of some of the internal workings of the TCM22 in another thread under New RIA TCM22 if anyone is interested.

My mistake, after more magnification the 9mm.barrel is not ramped. I was going by what Globetrotter said.
