I recently purchased a XDM40. Wanted to shoot it with my father, and the flat nose, and hollow points I have to shoot kept jamming on the ramp into the chamber. Or I think it was the ramps issue. The slide would not fully seat with a round from the magazine, sticking out just a 1/8" or so. I can put a single round into the chamber and it slams forward as should. but feeding from the mag is no go. My son mentioned other XDM users have this issue. The ramp looks steep to me, but who am I to judge. Any suggestions??? Pull the barrel out and polish it, will that help or interfere.
