I don't know too much about glocks...but, just today, my brother and i were talking about today's handguns. Apparently, Oakland PD just recalled all their Gen4 Glocks back in May...maybe for the spring issue?? Whatever the case, i think that Glocks are fine guns. Their trigger is too light for conceal carry IMO, but that is just me. If you like Glocks, then have you tried Glock 26 which is smaller and thus easier to carry. And since there is no Gen4 Glock 26 (Note: i am outdated w/ Glocks), then i would trust G26 over the newer Gen4 Glocks. Otherwise, if you are sure that Gen4 has no other issues, then go for it. Glock customer service have a good reputation...at least when i had my G26 several years ago.
