I've had my XDm 9mm 4.5" for about 2 months now and not a hiccup. Just put another 50 rounds through it this morning, brings the total up to just under 200. I've shot Hornady Critical Defense, Federal Classic JHP, Remington UMC FMJ, and Blazer FMJ (this morning). I was somewhat worried about the Blazer, but it performed like a champ as always.
