Took my boy to the range today. Had a lot of fun. However, when loading a mag in my Kimber UCII .45, I ran into this issue. It happened to be the first round in the mag, and it jammed on the ramp, preventing it from feeding. I cleared the jam, and looked close at the round. It was missing the ejector flange at the back side if the casing. I have never seen anything like it. Neither had the range master. It was really strange. Glad it happened at the range and not when I was counting on a bang when I needed it. Kusdos to my boy for noticing something was wrong even before he tried to pull the trigger!
