I got my Glock back from Georgia today. I sent it in because of the dreaded BTF was serious on my G17 gen 4. I haven't had time to take it to the range, and won't until this weekend. But these are the only descriptive words on the paper they sent with it. Do you think "upgraded" means they changed anything on it??? Posted using Outdoor Hub Campfire Wanna kill these ads?
