I think the biggest advantage in CTC laser grips is for "dry firing" to see if you are flinching or something. As far as self defense, IMO, why would you want to give your position away with a laser beam shining off you weapon? CTC's look cool, but I wouldn't buy them again if I had the choice. Yes, I have them on my Beretta M9 because I thought it would be neat to have for certain reasons, but I hardly use them. Sorry I didn't brag them up, but, that's how I feel.
