I'm sure its ok, but I've gotten away from +P even in a larger 9mm weapon. My feeling is it handles differently from practice/range ammo, its a little harder get back on target, a little more wear and tear on the gun, and not enough benefit to outweigh that. I assume those negatives are even more true in a small 45 though I don't own one myself.
