Was over at Tri County this afternoon and had a jam in my XD 9 Tactical. Fired three rounds from the mag and then the fourth bunged up the system and I could not open the slide. So, I bagged the gun and brought it home (somewhat nervously as I could do nothing at the range). I managed to 'pop' the ejector and free the slide from the round and then levered(carefully) the round from the chamber. Looks like when I dropped a round during loading (and I am fairly sure it was this one) it must have tilted the bullet in the casing. The round was all askance and there was a distinct bulge at the base of the bullet that caused it to jam in the chamber! So, a lesson there is "handle your rounds a little more carefully, especially when there is concrete beneath you!
