Gen 3 for me thanks.....the Glock is a tool, nothing more, nothing less (by any means). Offering armchair commando options on the Glock won't sell me, but hey, get what you think will make you happy. Autoloading handguns are a last resort or extreme close quarters option for me, reliability above all else....hence the beauty of a Glock 17 to me. Nothing has stopped mine in thousands of rounds, not underpowered Winchester white box or sub gun ammo. Get it, shoot it, get proficient with it out to 25m, and be happy.
