I recently picked up a used 2nd gereration glock 19. A friend gave me a few boxes of 9mm ammo that he no longer had a need for, he's a LEO and they have switched to .40's. One box is made by Winchester with the word 'ranger' printed across the 'W' logo, and says 'For Law Enforcement Use Only'. They are 115gn JHP and marked 9mm+P+, that's the part that my question concerns. Can one safely shoot +P+ in a Glock, as it doesn't have anything stamped on the gun, as I thought all +P rated guns were. He says he's shot 'thousands' through his old 17 that he used to carry. Just wondered what you guys thought on this, thanks in advance. JR
