I was digging through an old stash of stuff and came across 2 boxes of 9mm 115 grain JHP factory +P+, one Federal, one from an LEA Winchester restricted issue. I had been doing some LEA-related instructing over 10 years ago and was often told to take any left over ammo with me because the agencies hated to do the paperwork to put stuff back into inventory. My question is, what pistol can this stuff be fired in safely? If I recall there was/is no real standard definition of what +P+ pressure actually is. I was thinking perhaps the 9mm cylinder in a Ruger .357/9mm convertible might be safe. What say you folks? GF
