Easy to install, easy to activate, easy to see - Crimson Trace Laserguard Green Laser Sight for Glock 42 & Glock 43

The Crimson Trace Laserguard LG-443G green laser is easy to install on a Glock 42 - just snap it on the triggerguard and tighten the tiny Allen screws with the tiny Allen wrench provided in the kit. It is also simple and easy to activate - just take a normal firm grip on the Glock and it comes on automatically. (With a little practice, you can loosen your grip on the activation button just slightly to avoid activating the laser if you want to.) It does not materially alter the "feel" of the grip, IMO. The green dot is also really easy to see, even in daylight (at least out to 25 yards, which is as far as I tested it.) It is much easier to see that red laser dots in all light conditions, and (for me, at least) it makes it easier to shoot accurately when practicing weapon retention drills in which the pistol is tucked in closer to the body instead of extended as it would be in a more normal shooting stance. It's a handy little gadget!
