My ccw is a Glock 19 in a leather Bianchi IWB holster. When the holster is out the gun comes out all right (still being broken in) but when the combo is actually in my waistband, it's very sticky drawing the gun. Instead of the gun coming out cleanly, the holster wants to pull out or pull up my belt/pants, I guess because of the pressure on the outside of the holster. Do any of you guys have any good methods for getting the inside of the holster more slippery? The kind of rough texture on the Glock slide doesnt seem to help either. Thanks!
