.22TCM9R in a .22TCM?

Those of you who were at SHOT, did the RIA folks say anything about being able to shoot the .22TCM9R in the standard .22TCM guns? I would think a slightly shorter round shouldn't be a problem in the .22TCM unless it is significantly shorter.

Just wonder what will happen to the standard TCM if the 9R takes off with the conversions.

The 22TCM9R case is a 22TCM shortened to the length of a 9mm Luger case.
The gap on the case shoulder in a 22TCM chamber would create problems I would think.

This would be a question for an RIA engineer.

If you go to this link, you will see that there is a significant case length difference between the 22TCM case and the 9mm case.

With 22TCM ammunition just fairly recently becoming readily available, and the Glock conversion not even being released to the public, it will be a good while before this new cartridge will be easily available.
So, RIA will have to come out with an official position on this subject of shooting the new cartridge though a firearm chambered in standard 22TCM before a bunch of guns start showing up at the factory for repairs due to using the new cartridge in them.

Just listened to Fred Craig talk about the TCM 9R versus The 22 TCM, what he said is that the case is the same, powder charge is the same but the bullet is shaped a little different to shorten it enough to fit into a 9MM magazine. Bullet weight is the same. With that information my guess is that it would work in the 22TCM. I don't have an answer back to say for sure. You can see the video on Armscor's face book page.

Now I will have to find the article again that I got my information from.
So much for having to be the truth because it is on the Internet......

Watched this earlier today. Now I feel pretty good about what I posted a couple of weeks ago on the INGO forum:

"Looks like the TCM brass, but a shorter, round nose bullet. Only need about 0.1 inch pinched off the standard TCM to reach 9mm COAL. "

It all depends on where on the internet you look.

The photo below comparing a 9R round to a standard TCM round was posted some time back in the 22 TCM KREW group on Facebook by Ian Mcfarland with Modern Weapon Systems:

I was told at the SHOT Show last week in the ARMSCOR booth that the new TCM round with the shorter bullet would shoot fine in my 1911 TCM, as well as my TCM rifle. I did not realize the new round had a different caliber designation, though.

The new round was the one on the left above, but I did not have one of the original TCM rounds to compare it to at the time.

I also recall from SHOT Show 2014 from my discussion with Martin that even way back then, they were talking about the new 22TCM round with the new hallow-point bullet and that I should be able to get it later in the year (2014).

I believe this was done so they could release the 22tcm conversion for a glock 19(?) which will be a conversion slide to fit a stock lower and mag

It's actually a Glock 17 conversion. I handled their sample at the show. It consists of a whole barrel/slide assembly and will cost $400. They also said it should work on my Glock 22, which is the same frame as the 17, but is .40S&W. $400 is more than I paid for my used Glock 22 Gen 3, but I'll probably still get one. (That is, unless it only works with Gen 4 or later, which I'm hoping is not the case, or I'll have to get another Glock.)

Well with a TCM FS, MS, and rifle, I doubt that I will have to worry about using the 9R, but good to know that it will work. Guess if I ever needed to I could lop off the nose of the 22 TCM to make it shorter. :-)

Ummm....no. The OAL of the 9R round (bullet+cartridge) is approximately the same as a 9mm round, meaning that the new round will fit in 9mm magazines.

The 'R' stands for the revolution that this makes possible: Converting 9mm handguns to TCM.

Man, that is one stubby bullet ! Good thing the case is a bottleneck design, I can't imagine that sawed off bullet would feed very well otherwise.

The new ammo WILL work in the 1911 TCMs, but Will NOT work in the TCM Rifle. At least according to the news release on the Armscor site.

Not a cheap conversion, but what the heck, if you are a Glocker you might want to spice things up a bit.

I just happened to visit their site last night and saw that. I'd wager that the round WILL fire when chambered but WON'T feed reliably, but that's just my uneducated opinion

.22TCM and .22TCMr ammo interchangeability.

I would suggest, instead of listening to the keyboard kowboys on the
web that you email Shawn Fairbairn at [email protected] and
take his advice. He is the head gunsmith there.

Interestingly, the 22TCM9R bullets are only one grain less than the 22TCM bullets, but are seated more deeply into the cartridge. I pulled the bullets from both rounds to compare. See the photo (with my Glock 17/22TCM9R conversion in the background).

This photo is from my thread that I posted on my Glock conversion, which can be found here: https://forums.1911forum.com/showthread.php?t=480171 .
