Used my Glock 19 for the first time since I installed the Lasermax guide rod laser. WOW! Pretty awesome. I wasn't used to shooting without aiming with the sights, so at first that was a little weird. Very accurate. They did turn off a few times on their own, but I just turned them back. I had to wipe the front of the laser a few times because they tend to get dirty quickly. They are great for rapid fire shooting and wrist on hip shooting. The targets were 25 yards away and the laser was pretty easy to see, but it was raining so I don't think they would be that visible on a sunny day from that distance. All in all, I have to say they are pretty effin cool. I'm glad I got them and would recommend.
