It absolutely will not damage it. It is a good quality firearm, only thing that may happen if you shoot a LOT of them (doubtful that one would do such a thing) it will wear the recoil spring out earlier. Maybe. Just an aside (and completely an opinion so take it or dismiss it for what its worth) based off years of 1911 (especially Kimber) shooting, CCW, and some research I dont use +Ps in a 45. They really arent needed and make the second shot much more challenging than with standard loads. Plenty of power as she is. Again, take it for what its worth. Good luck, hope this helps.
