We've had two of the 9MM ported XD's as rentals. Both of them broke in the same way. The thin strip in the front of the slide that is between the barrel ports cracked at the front and the strip of metal bent upwards. Both times the shooters came out and said, suddenly, I couldn't see the front sight. When we sent the second one back, we asked for a non-ported replacement and SA sent one. No problems other than that.
