The XD40 I had was not marked on the barrel for +P's so I called Springfield and asked them if I could shoot +P+ out of it and they said yes.
A gun that is not marked +P is NOT designed for overpressure rounds and is NOT safe to fire +P rounds.
Same with the Sigs. They state in the manual that +P ammo is acceptable for use in their pistols (aka doesn't void warranty), but +P+ is not. My guess is that as stated eariler +P+ isn't a standard so much as a marketing device. +P is a defined objective standard.gudel said:I don't see any +P marking anywhere on all my HK's, but it is written so in the manual that it's okay to use +P in my USP9, USP45.

I had thoughts in that direction, then today while looking at a 38 the fella behind the counter said "+P refers to the 'partition' in the hollowpoint," meaning that little post in the middle of the hollow point tip.
