I bought this new for 3 gun shoots and have probably 3000 rounds through it. I've heard the slide cracks. Should I look for anything else?
The 3 gun shoots a long time ago had an unlimited class. To the point and answering the question, it's a .40 caliber.
And I don't think you'll see cylinder timing problems on an XD.I doubt the slide on that revolver will ever crack.
