Top performing laser sight for any rail mount pistol - Crimson Trace CMR-201 Rail Master Red Laser Sight w/ Universal Mount

I have two of these now. The first one went on my M&P-9 and the second on my M&P-9c. They are easy to install and require little adjustment to zero. They are a great aid to aging eyes in varying light conditions. I know you are not supposed to become dependent on such tech-gadgets but you will find it hard to resist such great aids to quick and accurate shooting. In the world of laser sights Crimson Trace leads the pack. You can't make a better choice.

I may need more of these for my Springfield XD-45 pistols.
