Greetings NWFAers, I bought this at my LGS about a month ago, noticed the USA on the slide and went "huh, that's cool". Haven't thought much about it until today, when I decided to look a little bit deeper into these new markings. I was surprised how little Info I was able to dig up... I guess I'm just wondering if anyone else has seen any of these locally? As far as I knew, US made glocks were for export only. So what's changed? Is it a different finish on the US Gen4 slide than the Austrian marked Gen4's? Thanks in advance everyone.
