Ultra compact green laser aqptlmg - NcStar Ultra Compact Pistol Green Laser Sight

First, the negative: You can't put this laser on a Buck Mark Contour because the front sight blocks one end of the rail and the rear sight blocks the other end; one end of the mounting rail must be unencumbered because this laser slides on (can't be "dropped on" over the middle of the rails).

On the plus side, it's the smallest, shortest, and brightest laser I found, and the price is quite acceptable. With a rail that's open on one end, the quick release feature allows easy, fast, one-handed mounting and removal.
Pros: light weight, short case, quick release
Cons: must slide on from end of rail (not the middle)
