GLOCK ARMALASER REVIEW
Designed specifically for all 9mm, .40 S&W, .45GAP, and 357SIG Glocks. Will also fit Slimline .45ACPs. Touch Sensor - utilizing human touch conductivity technology. Simply touch metal sensor (basically as soon as finger enters trigger guard) and laser will activate. Windage & elevation adjustable. 635nm 5mW. Made from the same DuPont Zytel engineered polymer that the pistol frame/grip is made from. Price $120. This is from their website.
Armalaser also offer a trade in for different pistols for $29.00
Armalasers make some affordable lasers that get the job done. The down side is that you need a special holster if you want to you it on your EDC handgun. Their lasers are super bright, easy to adjust, hold zero, and are light weight.
Price and function make the Glock Armalaser a GO. I would highly recommend this laser if you have a dedicated home defense handgun. The swap out program Armalaser offers is also a selling point. I have alot of friends who change firearms like underwear, if you fall into this category take a look at Armalaser products. They are good at what they do.
