Hey guys just looking for some opinions here. Ive been considering the g21 gen4 for awhile now and think I'm fixing to make my move. I have a gen 3 g19 and enjoy it but I want to make the jump to .45 auto for the main reason that I feel more confident in it being my SD round. I've shot the gen3 g21 and loved it but like the feel of the gen4 better. I shoot very well with .45 and the g21. I guess my questions are has anyone else made this transition? And are u regretting it or happy with it? And how are the gen4 21's treating you?
