Have an XDm .45, 5.25. It shoots like a dream, is very accurate, and fits me ergonomically well. However, I have run into a recurring problem in 2 of the last 3 range sessions. Using Federal 230 gr FMJs purchased @ Wally, I have had numerous failure to fires. Sometimes every other round, rarely consecutive rounds. I have lubricated thoroughly, and clean it after every use without fail. I took it to my local gunnie, explained the problem, and brought along 10 FTF rounds for him to try. The rounds showed a light primer strike. Wouldn't you know it, all 10 fired consecutively into his can! I have no ideas, except for the ammo. I ran a box of WWB thru w/ no miscues. Any ideas out there? I'd greatly appreciate any input. THX!
