Gaston Glock has proven to be the greatest gun maker of all time. So what is up with the gen. 4's? Quentin just posted a thread about a recoils spring exchange and I've heard other chatter about this and that. I at this time owning 3 guns, 2 Glocks, I wouldn't buy a Gen. 4 on a dare. They could have just kept the Gen 3's and just modified the frames or what not.
