I was contacted today by Armscor about a new round called the TCM 9R which is set to be released in June. The round is designed to be compatible with non-1911(will work with Armscor 1911) pistols and so it is slightly shorter than the 22 TCM and matches the 9mm Luger/Parabellum in length.  Armscor will be launching the new round with conversion kits for Glock G17 and G22 Gen1, 2 and 3 pistols. From a Glock the round will hit 1900-2000 fps!

The round is also compatible with all 22TCM chambered Rock Island 1911 pistols. The MSRP of the Glock conversion kit will be $429.

The Press Release …

ARMSCOR’S NEW TCM 9R AMMUNITION
DESIGNED FOR 9MM CONVERSION KIT COMPATIBILITY
.22 TCM 9R Ammo Caters to Shooting Enthusiasts of Other Popular Firearm Platforms

February 17, 2015 (Las Vegas, NV) – Armscor and Rock Island Armory, the leading 1911 pistol and high performance ammunition manufacturer, continues to innovate the firearm industry by expanding its growing line of ammunition with the release of the TCM 9R round.

The TCM 9R round does not replace the existing TCM factory ammo, but enhances the company’s offering to consumers. The ammo matches the length of a 9mm round allowing it to feed and function properly as well as function with Armscor’s new TCM / 9mm pistol conversion kits. Given the average velocity of a 9mm round, consumers can expect to almost double their bullet velocity when exchanged with Armscor’s new round (TCM 9R velocity: 1900 – 2000 fps).

Just like the existing TCM ammo, TCM 9R ammo also functions in TCM chambered 1911s from Rock Island Armory.

“This is an exciting expansion to our wildly popular TCM series. Not only can the new TCM 9R be used in any existing TCM platform on the market today, but we will be releasing a series of barrel and slide conversion kits that allow other existing firearms to enjoy the higher velocity of the TCM round” said Armscor President and CEO, Martin Tuason.

Armscor and Rock Island Armory plans to launch other products that will utilize and bring the exciting TCM 9R round to the forefront of the industry.

This product line currently includes the conversion kit for GLOCK generation 1, 2 and 3 in the G17 and G22, scheduled for release in June 2015 at a $429 MSRP. Minor gunsmithing is required for proper installation.

    I had a hard time reading past the first mention of the MSRP. The new cartridge looks pretty cool and sounds impressive, but paying as much money as a used Glock to shoot a round that may or may not catch on is disappointing.

    • If there was useful reloading data, I’d consider it. I have a Glock SBR, and wouldn’t mind giving it a more PDW-esque caliber.

    • Matthew

      429 MSRP. I paid 330 for my gen 2 glock 17. I’d almost rather save 200 more dollars and buy the current 1911 in 9mm/.22TCM and be able to shoot both types of ammunition through them, rather than have to be careful which rounds I can shoot out of the Glock. The Glock is also my carry piece, and is stock as can be, factory refurbished. I want ZERO gunsmithing done on it, because the thing runs perfectly as is, and I want nothing to change about that.

  • Ethan

    I guess I’m still just confused as to what advantage this cartridge offers @ 2000FPS. I’m not bashing it, I’m just legitimately curious/confused.

    • To Whom It May Concern

      Type IIIA
      (.357 SIG; .44 Magnum)New armor protects against 8.1 g (125 gr) .357 SIG FMJ Flat Nose (FN) bullets at a velocity of 448 m/s ± 9.1 m/s (1470 ft/s ± 30 ft/s) and 15.6 g (240 gr) .44 Magnum Semi Jacketed Hollow Point (SJHP) bullets at a velocity of 436 m/s (1430 ft/s ± 30 ft/s). Conditioned armor protects against 8.1 g (125 gr) .357 SIG FMJ Flat Nose (FN) bullets at a velocity of 430 m/s ± 9.1 m/s (1410 ft/s ± 30 ft/s) and 15.6 g (240 gr) .44 Magnum Semi Jacketed Hollow Point(SJHP) bullets at a velocity of 408 m/s ± 9.1 m/s (1340 ft/s ± 30 ft/s). It also provides protection against most handgun threats, as well as the threats mentioned in [Types I, IIA, and II].

      • Ethan

        So it’s going for “Armor piercing from a 9mm size handgun”?
        While that’d be cool, its not going to happen with soft point or flat nosed bullets I’m seeing it offered with currently.

        • Ethan no way it will be armor piercing.

          • Ethan

            That’s what I thought… which leaves the question: What is this round trying to be good at?

          • mig1nc

            They could go for the whole %weight of the jacket argument. I don’t put anything past the ATF.

  • Lovely. A niche variation of a niche round. If they had intended on making this thing universally compatible with 9mm magazines – and that would only make sense – they should have planned for that from the beginning.

    I had a lot of hope for this round, mostly because it amuses the hell out of me, but the handling of it has been… less than encouraging.

    • El Duderino

      Guess you’ll hate the soon-to-be-released .22 TCSSM (Super Short Magnum) that’s compatible with .380ACP guns!

    • Panzercat

      Yeah, it’s tough to get excited when the direction appears a tad scatter brained. I have to buy one type of .223 short for my 1911 and another type of .223 short for my glock, even though both made by the same company and almost-but not quite! -identical?

      Think i’ll pass on both now, thanks.

  • Paul White

    I like RIA, but really? This seems so pointless.

    • Albert Einstein

      Not really. It’s basically the exact same thing as 5.7×28 ballistically, except it’ll fit in a pistol that’s not laughably large.
      The 5.7×28 is slightly longer than a 357magnum. The reason no one has made a 5.7×28 1911, for example, is because the grip would have to be larger than that of a Coonan 357!

  • nobody

    Just when I thought this couldn’t get any more stupid. What are the bullet options for this cartridge going to be? Something tells me that there aren’t going to be many. What they should have done is shortened the case accordingly so they could have at least used the same length bullets as the regular .22 TCM.

    • Adam C

      Give the tcm a try, you might like it. Which may lead to you buying it, then buying reloading dies for it. Could be fun.

    • Albert Einstein

      I dig it. I LOVE the 5.7×28(I wish they had a good rifle or pistol in 4.6×30), but 5.7×28 is just too damn long to fit in a normal pistol. 5.7×28 is longer than 357mag.

      5.7×28 should have the same basic lethality as 9mm, while having far lower recoil, making for a pretty fantastic pistol… which is where shortened 22tcm comes in, so you can actually have a normal sized pistol.

  • Vitsaus

    I can’t wait for 6 months from now when some new proprietary round comes out and everyone is like “TCM who? Is that like, what the P90 shoots?”

  • DG13

    I have been searching for the max pressure of the TCM round for a while, and can’t find it anywhere. Since it now will go in a glock conversion, perhaps it is the same as 9mm? or perhaps since it is basically a short .223rem round it shares the pressure of the .223?…..anyone know for sure?

    • Albert Einstein

      I do not know for sure, but guessing isn’t so bad. If it’s pushing the same velocities and same weights as 5.7×28, it’s safe to assume it’s got same max psi of 5.7×28.

  • Yes but nobody wears level II vest anymore. I tried it on a non-expired level 3 and there was no penetration.
    I always wore my steel plate in my level 3 just as extra protection.

    • Marc

      Of course it won’t penetrate level III body armor which is rated for 7.62×51 NATO. It will go through all soft body armor though, including IIIa.

      • To Whom It May Concern

        I searched for any 22TCM test on type IIIA, but the expired type II was what I came across, instead. The advertised velocity does exceed what type IIIA is rated for… I’d be satisfied with the results of 3 chronographed tests on unissued IIIA, in multiple bullet styles.

    • Albert Einstein

      Level III is rifle plates. Level IIIA you said, and you would have had some credibility.

  • Christian Hedegaard-Schou

    This is going to die so fast and so hard as people buy conversion kits and then buy up tons of regular .22TCM ammo, only to realize that it doesn’t fit, doesn’t function, and doesn’t fire and they can’t return their ammo.

    Oh well.. For those of us who want to give the round a shot, I bet there will be TONS of secondary-market .22tcm ammo to pick up on the cheap on gunbroker as people try to at least recoup some of the cost of their mistake.

    And for those of us with 9mm 1911’s, sounds like both rounds will be compatible (same cartridge, different bullet seating depths) if we eventually want to pick up a .22tcm barrel on the cheap for fun.

    • Panzercat

      That’s a sad prognosis, but i can easily see it happening.

  • noob

    why didn’t they make it 9mm conversion capable in the first iteration?

    • herf

      it is was just not for glock mags when i put 22tcm a round in glock mags it a couple thousands too long the 1911 mags are longer because of 38 super

      • noob

        ah! I get it now. the 22 TCM 9R isn’t a whole new round, it’s just got a shortened OAL, with the chamber pressures being the same.

        a shame they didn’t test it with glock mags from the get-go but I guess when you invent something you make it work with what you have on hand at first. RIA were 1911 guys, so they invented it for the 1911.

        • herf

          well i would be curious to see if a .40 S&w mag would work do to it having a longer overall case length and still use a standard 22 tcm rounds

          • Marc

            .40 S&W has a shorter OAL than 9 mm Luger.

  • Giolli Joker

    What I don’t get is the fact that this conversion kit includes a new (lighter) slide to cycle these rounds… therefore I don’t really see the point:
    if you have compatibility with 9mm Luger, a relatively inexpensive conversion that requires only to swap barrel and recoil spring would be interesting… if you need to replace the slide as well, let’s just forget about designing a new round, just make conversions in 22TCM aimed to the 45ACP framed Glock models.

  • gunsandrockets

    So, reinvention of the .30 Luger?

    With the proliferation of quality expanding bullets, .30 Luger would have a lot going for it.

  • Andrew Hobby

    Dear Armscor,

    Just Stop Already.

    Whats next? The .223 TCM, which is a 22TCM necked down to 9mm and then necked back up to .223, and finally reamed to 5.56?

    SERIOUSLY. JUST STOP ALREADY.

    • Albert Einstein

      I bet you are fun at parties.

      • Andrew Hobby

        “You know that the cake you’re eating is LOADED with calories? Right? RIGHT?

        Why is everyone walking away?”

  • Pedro Marcos

    I wonder what the .7.62 Tokarev case could do to with a 5.56 bullet. Or 6.5mm.

    • the ammo addict

      Check out the .22 Reed Express, designed as a drop-in barrel conversion for CZ-52 pistols.

      • boris

        actually 7.62×25 was and is the daddy of all these – small fast modern kevlar drillers. it kicks uckin as$ but people like modern stuff.
        when and if russians come to their senses and modernize this bullet, all the new fad will just become quiet and never talked about again.

  • dan citizen

    .357 sig, or Tokarev if you’re broke.

    Either of these will provide an indistinguishable wound path from this new round, avoid the fruit-fly-lifespan of a new cartridge, and save you a bunch of money.

  • richard scalzo

    Put that right up there with the 356TSW and the 327 Magnum.
