Crimson Trace Green Lasers For Rails, Glock 42

Crimson Trace was awash in new products at the 2015 SHOT Show. Laserguards for the M&P Shield, Compact, and an integral laser for the Bodyguard and other firearms meant there was a lot to cover. However, two products caught the most attention: The green Rail Master laser, and the Laserguard for the Glock 42.


The new Rail Master green laser. This comes with adapters for most common handgun rails.


Green lasers are easier to see in the daytime, but suffer from worse battery life:



Like optics on rifles, the cost of a quality laser for your handgun will be a significant percentage of the cost of the firearm itself:


The Glock 42 laser makes for a very small and tidy package, able to be carried most anywhere, in any type of outfit:



The Glock 42 laser, like all Laserguard models, does change the outline of the handguard:

    I paid about the same amount for the CMR-205 Rail Master with a red laser. It’s an awesome laser/light combo, but I think I’d like the green laser even better, despite only getting half the battery life. I’ll be buying more Crimson Trace Rail Masters for other firearms, because it’s just such a nice compact lightweight high quality laser and light combo. I’ll probably get one in green next time.
