I have an XD45 4". I was cycling some defense ammo and when I pulled the trigger it went "tink" instead of "boom". I looked at the cartridge and it had a slight dimple on it. It fired first time through my Sig.
I field stripped it, checked for obvious things (not a gunsmith). Did this twice, on the third field strip it started working again. 200 rounds later it's still fine.
Has anyone else had this problem? Was it something I did or didn't do? I've had this thing for over a year now and shoot it regularly. It aways gets cleaned. I'm kind of lost as to what to do. I found a few sites that show me how to detail clean the slide and will complete the cleaning and see what happens.
Overall I'd say this pistol has had at least 3000 rounds (estimate) through it without a problem.
