I have a WWII Russian PPSh-41 submachine gun. The original caliber is 7.62x25. First I had a 9x19 barrel made so I could shoot 9x19 and conserve my stash of Norinco 7.62x25. I wanted to convert it to a cartridge like the 9mm Mauser Export, which was said to be one of the best subgun cartridges, but after WWI, 9x19 was adapted by most European countries. I learned of the 9x23 when I was discussing this with an IPSC shooter. Almost the same dimensions as the 9mm Mauser Export! And the thicker web appealed to me since, with the PPSh, I needed a hotter load than normal. The 9x23 really rocks in my PPSh! A 71 round drum in 9x23 in full auto is quite an experience. :grin: Shooting 124 gr TCJ with 8.2 grs VihtaVuori 3N37 at 1551 fps and a cyclic rate of 1118 rpm. What a hard hitting round! Hotter than a .357 Mag. It really takes the steel down with authority! I have experimented with different powders and bullets (95 gr, 124 XTP and 147 gr).
Have a Star Model A that has a custom made piston type recoil rod that I shoot 9x23 through. Usually download the rounds for this pistol as a safety measure.

That PPSh-41 in 9x23mm sounds fantastic! I imagine the newly imported Czech Model 24 kits could also be easily built up into 9x23--- but as post sample guns only! In semi-auto land you could probably modify a .45 Marlin Camp Carbine but the rebarreling costs would be expensive.

Similar to your Star, I've got a Star Model B Super in 9mm Largo that deserves some customizing...maybe to include rebarreling into 9x23mm? Who did your work? Is this feasible/desireable/safe?

Firar,
I thought a Star Model B was a 9mm P and the Largo was a Model A. Otherwise the same.
Anyhow, a 9mm Largo IS a 9x23 (by case dimensions, NOT by load) and I would not be surprised if a 9x23 Winchester went right in. If it did not, it would probably take only a touch with a reamer. Now you could load the gun to approximately DOUBLE its design pressure. And they say Spanish steel is a little soft. Load 9x23 Win down? Now you are back to Largo. Why bother? Separate ammo for pistol and subgun/carbine? "Let's see, now, did I put the pistol ammo in the blue box and the rifle ammo in the green? Or was it the other way around?"

Is this feasible/desireable/safe?

Largo runs in the low 30K CUP and 9x23 Win runs in the HIGH 40K CUP.

SAFE?

NOT A CHANCE! This is a very bad idea to run 9x23 Win in any of the older guns or any of the new guns not designed for it specifically.

Yes, both make valid points, but I'm a guy who put a Kawasaki engine on a hangglider, skydive and blown up a 40 S&W Glock and a .357SIG Glock. I'm used to living on the edge. As I said in my post, I download the 9x23 for the Star, so basically I'm shooting a 9mm Largo round. And I don't mind having a different round for my carry weapon than for my subgun, though I can see the benefit of having a standardized round for both weapons. If it came to a "Notlage" I probably would put my PPSh in 9x19 and carry my Glock 17 as a sidearm.
Pistolsmith is a great forum!
