I have the chance to pick up a Gen 3 Glock 23, 2 (10 rd.) mags, and about 50 rds of ammo (some FMJs and some HPs) for $435.00. The gun is in as-new condition. Almost never fired. It belongs to a good friend who is utterly meticulous about how he cares for his guns. What do you think? Good deal or pass?
