Not to be a party pooper, but I did run into a problem with a retaining pin for the firing pin assembly on my XDm 3.8 Compact 9mm. Gunsmith says they are having problems with the retaining pin. I had about 1000 rounds through it plus about 2000 to 3000 dry fires. Dry fires didn't seem to affect the gun at all. Gun jammed (on a dummy round, not factory loaded). Clearing the jam appears to have broken the retaining pin.
That said, I love my XDm and plan to get either an XD or XDm 45 full frame soon. Maybe one of those 5.25" barrels (drools heavily). Just need to decide whether I want to stay with XDm or drop back to XD which does not appear to have had the retaining pin issues. But XD doesn't have 5.25" barrel
