LaserMax Review G21 & G19...
We installed LaserMax in our G21 and G19, in 11/2005 and 02/2006 respectively. To date, we are very pleased with the operation of both units.
Initial installation takes a few minutes, and close attention to detail is required, but once that's done, removing and reinstalling the LaserMax is about as easy as popping in (or out) the OEM guide rod.
Collimation is unnecessary, as LaserMax units arrive ready to go. On both weapons, POI is just above POA, out to the back of our range. Both our LaserMax units have thousands of rounds on them, and have held zero just fine. Both our LaserMax units still have all original components, including battery caps, springs, and even batteries, for that matter. They have proved to be rugged and reliable.
The only glitch has been that the LaserMax unit in my G21 occasionally turns itself on while firing. It has, however, never failed to activate. I accept this... The unit in Judy's G19 has been flawless.
I don't know that setting windage and elevation is a big advantage on a pistol-mounted laser. These units are used for self-defense, and not sniping. LaserMax is certainly accurate enough for SD/HD purposes.
There are two schools of thought for setting a laser, and both work:
1) Parallel Beam
2) Sweet Spot
1) With the LaserMax's emitter so close to the bore axis, the Parallel Beam approach works just fine, with beam and bullet running parallel out to practical pistol ranges. The offset between the red dot and the round hit is less than 1/4" in both our guns, and I can routinely "core" a target with either pistol.
2) The Sweet Spot approach has the laser intersecting the bullet's path at a distance determined optimal by the shooter. Inside or outside that distance, the beam and bullet grow farther apart; this becomes very apparent in laser/light combos, where the laser may be inches from the bore axis.
The LaserMax's pulsing beam is indeed easy to pick up on a complex background, and while LaserMax is not the brightest laser available, it's plenty bright for indoor use, in all but bright daylight. Attached is a pic of Judy's G19, equipped with Surefire X200B and LaserMax, pinning down a corner in a fully darkened room. Not bad for a pistol that fits in your pocket!
The LaserMax lens does indeed get clouded from muzzle blast. This happens far more quickly (say 100 rounds) with cheaper practice ammos. The premium ammos, with their cleaner burning formulas, cloud the lens far less. Again, these units are designed for self-defense, and it is unlikely any real world situation would result in hundreds of rounds fired.
Cleaning is simple. Just use a Q-tip and lens cleaner (or alcohol), and blast dry with canned air.
Lasers should not replace marksmanship skills. They are an augment to your arsenal, and properly applied, they're deadly accurate. Police departments report drastic increases in shooting scores with laser-equipped guns. Lasers also get the nod from our soldiers in Iraq that employ them.
Lasers offer many advantages, but intelligent use of them (as with tactical lights) must be studied and understood. It is true that the improper use of a laser (or light) could get you shot!
Proper use of lasers (and lights) offer many advantages--such as allowing you to hold zero on a perp, while dialing 911. They are also excellent training tools--Judy straightened out another shooter last range trip, with just four shots from her LaserMax equipped G19. New shooters are usually shocked at how unsteady their hands are!
For practice purposes, only a small percentage of time need be dedicated to laser training. Once you get it, you got it!
Removing LaserMax requires no tools. It's convenient that you can just pop in the OEM guide rod/spring for extended range practice!
The only other product we seriously considered was Crimson Trace.
While I would not hesitate to put Crimson Trace Grips on a 1911, or revolver, I did not like their impact on the ergonomics of the Glock pistols. The features of the Glock models are not common to the rest of their product line...
Conversely, I have read very favorable reviews on the CT grips from other Glock owners. So, I'd suggest trying both set ups before buying.
Overall, I give LaserMax a strong thumbs up, and recommendation.
