I've got around 1500 rounds through a Kimber Ultra Carry that I've carried for about 4 years. The only malfunction I've ever had was one shot, weak hand that I limp wristed. I picked one brand of defensive ammo that worked well and have stuck with it. I've seen lots of people poo-poo the short 1911's, but I've had good luck with mine. I alternate it with an XDS 45 that shoots about the same.
