Makes a good ccp even better - Lasermax Guide Rod Red Laser Sight for Glock42

Installation was very easy, as is activation. The auto shutoff feature is especially welcome considering this pistol is pocket carried most of the time. I also have a Lasermax weapon light on my G42, and the two together make for a versital if small concealed carry pistol. The recoil spring is a bit heavier than the original, but I got used to it in no time. It may seem like an expensive upgrade, especially when paired with the weapon light, but it is definitely worth it.
