NPG, Don't be sorry, it is very common and that is part of what makes me cringe.
I hope you let us know if a new Mag fixes the problem.
The main reason I mentioned it had nothing to do with you. I have 3 younger brothers, and we shoot quite often. However each one of them says clip every time they refer to a mag. Now to me that is little different than calling the trigger a toaster, so I usually respond when they, say, ask for me to hand them a "Clip" is to respond with, here is the "Maaaaagaaaaaziiiiine"(whispered pointedly). On Christmas Eve at the range this happened 2 or 3 times.
Finally My brother Cameron asked for me to hand him one of my Glock "CLIPS and I said (Whispered) It's not a clip,... It's a MAGAZINE!(not whispered). His response?
"Shut up and hand me the clip, Mr dictionary" LOL
