I have been talking to some of my old and experienced custom pistol makers. They all seem concerned about extra hot ammo and the lack of good primers, First they seem to think that some of the extra hot ammo is doing damage to pistols especially those being shot a lot, and the hardness of foreign primers. The American primer situation seem to be falling behind in production...Any body heard about these problems and what have you heard. Personally I would hate to ruin a custom gun by using ammo with to much pressure or pressure at the wrong time. I do know for a fact that our local department had trouble with frame cracking in Glocks shooting 357 Sig ammo. Traded their weapons back to Glock and went 9mm.. Any info appreciated.....Thanks
