I was at the local range Wed night for a handgun training class. There were 11 attendees there shooting mostly 9mm - a couple were there with .45s. I have my trusty G23 with me, along with 2 mags - have not used more than 2 mags in these classes up to this point. Instructor asks if we all brought 3 mags to class...oops. I mention that I only brought 2. He asks what I'm shooting. I reply a G23 and suggest maybe I could borrow a mag from the guys at the rental desk. And he says... "Nope... they don't have any .40 Glocks in rental... no one shoots .40 anymore". What!? Really? When did that happen?
