Has anyone experienced this? Today was the first time I shot my xdm 3.8 compact and when I was cleaning it at home after putting maybe 80 rounds thru it I found this spot that looks kinda like some finish came off the end of the barrel. Before shooting the first time I made sure everything was lubed as it should be so I'm not sure why this looks as it does... BTW this is my first time posting here. I have read and learned a lot on this great site... Thanks for any and all replies!!
