Hi JR:

Will a KKM drop in barrel work properly in one of your 6" long slides (w/no cut in slide) for a G21 (.45)? And what kind of velocity increases can i expect to get using factory ammo with longer barrel? This project is intended to be used for Bowling Pin matches.

I hate to say it but I don’t know what KKM barrels are doing for velocity? Your best bet is to shoot it over a crono and verify for sure!
Yes the KKM will drop right into our slide "if" it also fits a Glock factory slide.
