Sure Fire X400 ultra 500 Lu./ Green Laser Designator
July 18, 2014
High Price, Yes. High Quality, You bet. Does everything it advertises, Yes. The only problem was a previously purchased D.G. Switch for a specific H.K. Pistol. The S.F. X400 does not mount as far back on the rail as a S.F. X300. I will have to contact Sure Fire to obtain a solution. I have every confidence in S.F.'s Customer Service to come up with the answer, from previous contacts. Would I recommend this product to a friend? Absolutely!
