To each his own, I guess. I've owned all of the first three gens and played around with the 4th. Given my druthers, I'd take a tried and true 3rd Gen anytime. 4th Gens are nice, but there's nothing there that calls me. I've never had any problems with the mag releases on any of them. Seems my thumb meets them right there where it should. They accomplished all I was looking for in the 3rd Gens and you seldom hear anything bad about them from anyone who has half a clue. However, if the 4th Gens felt better in my hand, I'd probably feel differently. I'm sure they're just as good or better than any of them. Fortunately, I've never had a problem with that blocky feel from any of the generations. But, I do sweat profusely when it's hot and I appreciate the extra harsh grip texture the 3rd Gen RTFs offer. First and second gens seemed to slip around a lot, but I tend to like those big sharp bumps and finger grooves on the RTFs that fit my hand nicely. I don't think a person can go wrong with any of them, so the only thing left to worry about is which one feels and operates the best.Xd357 said:If I was to buy a new glock it would be a gen4. I like the mag release as it's easier to reach than the old one.
