My USA Made Gen4 G27 Review
I would like to hear from some Glock 27 Gen 4 owners that have a perfectly functioning handgun where the recoil spring is NOT in any way damaging or gouging the inside of the polymer frame.
Mine's been flawless with no gouging. I know Glock updated the Gen4 G27 spring number since it's been released due to it getting hung up on some of the earlier ones. Just something to be aware of.
The only guns I've seen with this issue have been people that use aftermarket barrels; it's (the gouging) not normal if running it stock. It is normal for the spring to come off the barrel during reassembly though.
