I have the Boomer in black nitride. I replaced the black rubber grips, which are excellent for managing recoil, but are IMO too large for CCW. With the Barami style smooth grips and a BK grip adapter, I can easily carry the gun in my waistband or in a holster. With the nitride finish, I don't have to worry about moisture (sweat) ruining the finish.
I've shot well over 100 rounds and close to 1000 dry fires and the action has smoothed out considerably. When I first got the gun, the action was rough enough that I could stage the trigger prior to let off. Now, it's too smooth to stage, a firm trigger pull results in the hammer dropping with no creep.
I'm carrying the Federal 200 grain LSWCHP.
