I received these in trade. Glocks are not really my thing, and I don't need these sitting around. First up is a KKM Match Glock 19 with compensator in the desirable black nitride finish, $295 new. The "Roland Special Barrel Package" Barely used - one range session. Sold for $200! Next up S3F Solutions Drop In Match Grade Barrel for the Glock 19, fluted with TiN coating, very minty. Sold on a different forum - it's gone.
