I have a newly built pistol built by an Army Armorer over ten years ago, but fired only two mags since. The frame is an Essex, the rest is USGI and is hand fit as tight as Fort Knoxx. He used all NOS USGI parts, new barrel, Colt slide, and all GI small parts. Is this pistol OK to fire +P .45 HP through? I shot two mags of Hornady Tap 230 gr. +P and placed all 16 shots in a hole the size of a solver dollar at 7 yards freehand using USGI sights. I did take my time somewhat, and got hammer bite twice. Just wondering if I am going to batter my gun to death using +P ammo.
