I give up...

I have been begging {literally, I call...} SIG and Ruger to come out with a auto pistol in 7.62x25 for years, ballistics that hover around what you describe. They staunchly refuse. Grip frame depth issues probably involved.

I carry a Tokarev in that caliber and it is hard to describe just how useful it is around the ranch and in the mountains. 85-86 grain bullets at 1400-1550 fps. Accurate, flat shooting, light recoil, and very lethal on varmints and butcher stock.

I predict the revolver cartridge will struggle and probably not make it, but the superb ballistics can't be denied.

BTW, a 6-inch barrel {for even a smidge more velocity} auto pistol chambered for the 7.62x25 and setup in a modern DA/SA mode pistol with a trim frame like the Tokarev would be the best general use field pistol {big game hunting not included} ever made.

I admit, I like it.

The Tok is a fine pistol, too, except it cannot be carried with a round in the chamber due to the positive firing pin.
