I would suspect that due to the intensity of the cartridge it is hard on the guns. Does anyone know if the service life/rounds fired for the 357 Sig is shorter/lower than for other pistol rounds???
I honestly believe this is it. I was told that the New Mexico State Police were having trouble with their Glock 31's chambered for the Sig cartridge. Seems the frames were cracking across the holes for the locking block pins.
I looked over a Smith & Wesson M&P yesterday that was chambered for .357 Sig. I was bringing home another purchase, or I'd have put it in layaway. 16 rounds of evil like that will keep the boarders at bay.
