I thought laser sights were a gimic when they showed up in the 80's, although some of the applications on machine guns made some sense for prison guard application. As they have progressed and become smaller and do not effect the overall dimension of the gun, I started getting more tolerable. When I watched the Crimson Trace episode of SG, that did change my mind, I had not considered the tactical applications of being able to lay in the street with the curb as your only cover and put a pistol across your chest and hit accurately without using the sights. Many more applications were shown that night, and now I have a pair of 205's on my S&W 940. I soon will get another few for my 649, and Glock 17.
