To me the better ergo's (better grip and mag release) of the Gen4 make it worth it. The Gen3 never fit my hand well which is why I drifted away from Glock, now that I have a Gen4 that fits great I'll never get rid of this one. Doesn't look much different but it is a HUGE difference for me.
Put some Ameriglo I-DOT Pro's on there and I'm good to go. This is my "go to gun" now.
