Galaxy black is a superb color to pair with the existing smoke grey grips. Fitment onto the lowered rail is very solid and has zero lateral play. However, the very end of the angled cut in the rear of the piece to fit onto the body sculpting was printed too far out and resulted in too much material to slide the rail all the way back to get the locking nut to seat between the picatinny teeth. After stripping the nut in the plastic threading, I chiseled the tail of the print down a few millimeters and managed to get the screw to fit snug again with some Teflon tape. Overall, I would expect a slightly higher quality dimensioned print but the end result after some TLC looks fantastic and provides a level sight plane down the barrel.
