I used to be like this about non OEM parts, but in this case I highly recommend the Vicker's mag release. It is a great product and an easy swap. I have them on my Gen 3 and 4's.I've had some issues releasing from my new Gen 4 G19 but I think it has more to do with my hand than the gun. I loathe gun modifications but I might just change up the release if I can't work it out with practice.
