I bought a new XDS. 45 a little over a month ago. So far I have fired around 75 rounds through it. I took it out yesterday to see if how it would handle the FTX ammo. I loaded the 6 round mag with the FTX ammo and the 5 rounder with Blazer fmj rounds. When I inserted the mag and racked the slide, the round jammed against the bottom of the feed ramp, something similar happened before with fmj ammo except the round went half way up the ramp and got lodged in the mag somehow. Anyway, while I was shooting the FTX ammo, I noticed debris flying around like chunks of the slug were tearing off. When I cleaned my gun, I noticed a lot of metal dust. I have fired a variety of fmj ammo and never experienced this. Is this common?
