Ive been playing with a Armscor 1911 chambered in 22TCM and also 9MM, The 22TCM can be formed using cut-down .556/.223 brass and has the same maximum case length as the 38Super and even uses a slightly modified 38super double stack magazine. To change calibers one only needs to change out the recoil spring and barrel assy. Which got me thinking about the Tokarev, The Tokarev Brass can also be made from cut-down .556 brass, and is only about .050" longer than the 9x23 (38super) and the 22TCM , why can't I simply seat the bullet slightly deeper, matching the TCMs maximum OAL add A 30cal barrel chambered in 7.62x25 and have a double stack Tokarev 1911? Anyway I found/ordered a 1911 barrel chambered in 7.62X25 and have made up some ammo with the revised OAL and was able to get a full 17rounds in the TCM's Magazine. Should be a fun gun! Top picture has the shortened 7.62 on the left next to the 22TCM and on the far right is a 9MM  Next shows a 17round TCM magazine fully loaded with 7.62 ammo.  |

The 7.62 x 25 is a hot little bugger.

Have you confirmed it Won't function with standard length ammo? That set up sounds more appealing and better thought out than the TCM!

Yes it is a hot round, seems pretty much match the 327ffederal with heavy bullets and beats it with light ones.
Yes, at first I thought it would work but when i got about 5 in the magazine it jammed, and because its a bottle neck the overall length needed to be slightly shorter tthen I first thought so it would not jam when pushing down on the neck to load the next round.
Can't wait to try this out.

I'm also very interested... only concern would be high pressures from seating more deeply, however if loaded lighter to allow for that, it shouldn't be a problem...
I'm not all that "up" on the 1911 platform, is there a way to add a buffer or is that done with higher rate springs, as the 7.62 is likely to batter the action more than the TCM... but maybe not much more than the 38 Super...
also I have a CZ-52 & hand load for the 7.62 X 25... the grip is much deeper to allow for the longer cartridge than I remember the 1911 platform having, unless that is just perceived as such???

Buffers were all the rage back in the 80s, I don't think they do much of anything other then giving the gun a point to fail, good springs and the right spring rate along with oiled metal is all that is needed.
The 22TCM uses a lighter spring rate(7LB) then the 9mm(12LB), and the 9MM uses a lighter spring rate than the 45ACP(16LB).
I suspect the tokarev will end up happy with a 12 to 16lb spring and will be as easy or easier on the gun than the 45ACP or at least easier on the gun than the 9x23 loaded to 55,000PSI.

Update,
My 7.62 "drop in barrel" showed up yesterday and came with a recoil spring, needed some fitting but everything was tight which is a good thing, first the locking lugs on the barrel were a few .001s tight for my slide, spent a few hours fitting it, same for the barrel to bushing, went slow, and only removed metal from the barrel so the factory 22TCM and 9mm barrels would still work, the 7.62 barrel ended up fitting the gun much better then the factory barrels.
ran a few magazines full of the 7.62 by racking the slide without any jams, next step is test firing.
On a side note, the chamber is pretty tight, looks like its supporting the whole case.
Can't wait to try some coated Hardcast bullets I have for my 327Fed.
P.S. got a message that 22TCM reloading dies were in stock from ammosupplywarehouse.com but they sold out in less than 2 hours and I was alittle slow to get mine, o well the Tok might be better anyway!

I have that barrel and I am going to use it in a "multi-caliber" 1911 project. I'm against deep seating the cartridge. Instead, I'm considering modifying the magazine to relieve the portion rubbing up against the bullet's nose. I intend to remove the front part of the magazine such that the nose protrudes through the opening into the magazine well. This may seem drastic, but there are enough 9mm magazines to use that it won't matter. FWIW. DW41F.

Several years ago, J&G Sales put up a video showing such a conversion. I don't know if any modifications had been performed on the pistol, but my guess it wasn't extensively performed on the 1911. That video showed the user firing off a full magazine of the Tok rounds out of the 1911. I'm working to mate a 1911 9mm slide to a Caspian frame so it will initially shoot 9mm Lugar. I also have the 1911 Tokarev barrel. My suspicions are that the NVA/Viet Cong conversion provided the modification to use a modified magazine. I'll provide more of my build as time goes on. DW41F.

Just a note. The legendary Swenson installed buffers in his custom 1911s. He was the man when it came to 1911s.

Why not ditch the buffers and use a flat bottom FP stop? Been using one in my Range Officer for the 260gr SWC loads and it has worked well. Shot a steel plate match last weekend using my heavy loads (260gr SWC's at 877fps) and the pistol ran without a hiccup. Matter of fact, I've ran close to 800 rounds through it without a single failure.
