Got my Gen 4 G23 little over a week ago. I have put over 500 rounds through it. Zero failures. My first Glock. Will not be my last. Nothing but 180s in mine. Tim
The malfunctions only occur in the 9mm Glocks. They used the new .40 recoil springs in the 9mm frames and the spring is much different from Gen 1-3, so it can not simply be swapped out. If you have a .40 (Which I always swore that I would never carry anything BUT a .40), you're good to go. I never should have switched to the 9mm. Grrrrrrrr.
