SecuritySix: Norinco makes a double stack Tok in 9mm, and I'm thinkin' that maybe, jes mebbe, the barrels might be interchageable - would really have to check on that, as that would be your double stack backup.
And yes, I would love a carbine in 7.62x25mm, or at least a bolt gun in that caliber.
I heard somewhere that the makers of the famous "Whisper" calibers has come up with two new ones: the 7.63 and the 7.62 Whisper. One is the 30 Luger with a heavy bullet and the other is the 7.62x25 with a heavy bullet. However, I'm willing to bet you will only find them in Contender or Encore barrels. However, last I heard, MCA Sports in Alaska makes chamber inserts for those cartridges. You could put the 30 Luger (.310 bore) through a 303 Brit or a 7.62x39 bolt gun, and the 7.62x25 through any 30 (308) diameter bore, either 308 Winchester, 06, etc. Might be fun but you would be limited to just one shot at a time.
I would love to see a Destroyer Carbine chambered in 7.62x25 but you rarely see those critters around any more. Maybe we could get one of the 9mm carbine types rebarrelled but I'm thinking a short rifle for small game work might be better. Just my 2 cents worth. Mikey.
