Just picked up my newest Glock, a G23 Gen 4, test fired January 10, 2012. I think I got a decent deal on it. $525 for the gun (couple boxes of ammo through it, perfect condition) and everything it came with new, a cheap cloth holster, and 218 rounds of ammo (50 rounds of Federal Champion, 82 rounds of Blazer, and 86 rounds of hollow point ammo marked R P 40 S&W--no idea what this last one is. Reloads?). It is my first Gen 4, and I'm very excited to see how it fires! It looks like people on this forum are generally happy with the 4th gen G23s. I have a 3rd Gen Glock 22, and I love the feel and the kick (almost a snappy feeling?). My Glock collection now consists of a 19, 21sf, 22, 23, and a 30sf. I'm very excited but already thinking about what's next on the list. I wish Glock would come out with a gen 4 20 soon!
