Anybody know if they (KKM) will swap and run correctly with the G4 stock barrel (That would be running a KKM STD G21 Gen3 SS barrel bought for a Gen 3 G21, and now would like to run that barrel in a new Gen 4 G21 model)?


I left KKM a message and did not get a reply. Thanks in advance for the help.

Should function, no problem
