A sweet little laser sight with mounting problems - TruGlo Micro-Tac Micro-Tac Tactical Green Laser

This product is a good idea looking for slight changes to make it even better. It is compact and puts out a bright beam which is adjustable vertically and horizontally.

However, the head of the mounting screw which secures the laser to my Glock's rail, and the Allen wrenches used to secure it and adjust it, are all so small that I found it difficult to attach and detach quickly. The design is such that if you don't set the wrench to the screw head exactly right, you'll probably drop the wrench. At least, that's what happened to me. Once mounted and sighted in to match your 3-dot sights, it functions just fine. But installation is awkward.
