We've got lasers for all three of our Glock pistols:
G17: LaserMax UNI-GREEN Rail-Mounted Laser
G19: LaserMax Guide Rod Laser
G21: LaserMax Guide Rod Laser
The Crimson Trace product is excellent, but I don't like it for Glock pistols...
I liked the first LaserMax (in my G21) so much, that I ordered one for Judy's G19! Both have proved excellent--rugged and accurate!
I was given the UNI-GREEN, green-beamed rail-mounted laser as a gift in June, and I'm very pleased with it! Its bright green dot is visible in broad daylight!
As for the pulsing beams, they have been proven to draw the eye more quickly, stand out better on a complex background, better intimidate a perp, and greatly extend battery life. There really is no downside...
The comments about lasers fast tracking trigger control and shooting skills are absolutely true!
The comments that lasers need not become crutches and replace conventional marksmanship are also true! That's like saying learning how to kick replaces knowing how to punch! Nonsense! Apply either as needed!
Laser aiming skills are quickly acquired, and after putting the LaserMax guide rod units through a couple a thousand rounds each, we normally pop in the OEM guide rods for range practice. It turns out, traditional marksmanship is where the fun's at!
Still, with proper trigger control, lasers are deadly accurate. Center mass hits at speed are easy, since the laser ostensibly projects the front sight onto the target. With a little care, you can routinely produce one ragged hole within the ten ring, per magazine, target after target. Yes, it really works!
Some additional thoughts about weapon mounted lasers...
Weapon-mounted lasers require practice and discretion for optimal use.
Walking around your home in a potential intruder situation, with laser blazing, is probably a bad idea...
Since a laser designator ostensibly projects your gun's front sight onto the target--in this case an intruder--you need not sight down the barrel! Better to keep your peripheral vision available for scanning your surroundings. Again, learn to see quickly!
A weapon mounted laser can allow you to hold zero on a perp using one hand. The other hand is free to open doors, loose the dog, call 911, or if you're very cool under pressure, finish your sandwich!
Extensive testing has shown that weapon-mounted lasers are proven assets on weapons platforms, when coupled with proper training and skilled application.
I've also seen the Crimson Trace video,
Shots In The Dark, and it is an excellent tutorial, well worth a look-see!
