Is there a way to ensure that you put the laser grips back on in the exact same place after removing them to ensure theyre still be zeroed in? Ive had two pair of CTLGs and think theyre great in many ways. My first pair was on a S&W Bodyguard and my latest pair is on a Ruger LCR. Both times that I went out and shot them for the first time I had to zero them in. After shooting them I went home and cleaned them (too good like I always do) and went out again and found the sights to be off zero. I figure this is because I took the grips off the guns to clean them. So I zeroed them again and cleaned them without removing the grips and went a third time and they were right on zero. I guess I can mark the revolver where a part of the grip is on the frame after zeroing but wonder if you scholars can tell me a better way. Thanks!
