Constant red laser beam is the highest power output laser commercially available. The built-in extra rail lets you keep all your rail space. It’s as small as a matchbox, requiring only 1.75" of rail space so it’s perfect for use on medium and full-size pistols, carbines, rifles, shotguns and more. So rugged, it will survive multiple drops on concrete. LaserMax even baked it to 350ºF and it still worked. Adjustable windage and elevation setting for precise alignment. Maintains alignment through battery changes. Uses two 357 batteries.
Ok I was hesitant on buying this for awhile but when I did I have to say it not bad at all after I sighted it in and shot with the laser on it stayed locked in place and did not have to re sight the laser at all. I shot about 150 rounds and had no problems. The only thing I have a problem with is the size of the tool to use to sight the laser. It's so thin and small I almost lost it twice since I got it a day ago. Also its a little hard to adjust the laser in with the tool because I'm afraid ill break it. Other then that its a good laser for the price
Easy to install on my Beretta PX4 Storm 45 ACP, and it worked first time. It is easy to change lithium battery and the laser is VERY bright. I could see it at 50 yards at high noon, bright sun light. I will be buying another one for my S&W MP 15 as well.
I purchased the Laser Max for my Glock 17, it fits like it was made for this gun. The laser works as described and after 1000 rounds it still functions as if I had just bought it. I have not had to adjust it since initial sight in. They recommend you clean the lens with a Q-Tip soaked in rubbing alcohol. If you clean it (only takes a few seconds) after 5-6 magazines it functions fine.
