A few years back I walked in with three Glocks and about a dozen magazines, including the aforementioned non drop free ones, and several 10 rounders bought during the Clinton "Assault Weapon Ban" years. I wanted one pistol checked out (since I was there) and two sets of night sights installed on the other two.Sorry to hear it, but it ended well. I've heard they have excellent customer service. I'll find out one of these days
I walked out with all new full capacity magazines, one pistol had all new parts except the slide, barrel, and frame, internals replaced in the other two, and two sets of night sights installed.
I was charged for two sets of night sights.
