I no longer keep an exact count but I've been putting hundreds of rounds through my XDsc almost every weekend. My count is just over 4000 or so and I've had zero gun related issues. I had one light strike not too long ago with a WWB but I've chalked that up to ammo, not the weapon. That particular bullet fired the second time through. I've fired all types of ammo, including some reloads from a friend but most were WWB, Federal, Blazer, Hornady, CorBon and Speer Gold Dots. A few weeks ago I replaced the recoil spring though I doubt I need too and I'm replacing the striker retainer pin with a PRP product though I'm thinking I don't need to...just for insurance and upkeep. A fantastic gun IMO that I trust with my life. Not my primary CCW carry but I use it for auto defense and occasional CCW. Might carry it more when I get my IWB Kingtuck.
