View Full Version : Gen4 reciever compatible with gen 3 slide.
I have a friend who has a Gen 4 Glock 22 that he is thinking of swapping a Glock 17 slide on. Will this work. I know you can swap the glock 22 top half with the glock 17, but are there unique issues with mating gen 3 and 4?
Nope, wont work. Yes the slide will go onto the frame but it looks nasty!
The Gen4 has a dual recoil spring. The Gen3 has a single recoil spring. There may also be an issue with the trigger bar engagement with the striker. The Gen4 pistols use a unique TB.
