Only the best - Crimson Trace Glock Gen3 Green Laser Grip

Crimson Trace is the leader & most sought after laser type in the handgun category, not just for its free cleaning swabs, free batteries for life and free cleaning/servicing of any problems.

Brightest light, be it red or green when compared shoulder to shoulder in all lighting conditions.
Lasts longer - changing batteries 1/2 or less as often as other brands.
Stays on zero longer than competition
Best fit to gun, still easy on-off as needed
LOVE the finger button best - able to go stealth then instant on to obtain a target looking for you

Tips:
the GRIP styles like this one will stay cleaner & on zero longer than (obviously) the GUARDS closer to muzzle blast & flip
of the GRIPS, finger buttons are easiler to manage on-off than rear buttons stay mostly on unless you relax your grip enough to be not solidly attached

The ONLY reason one would return this item would be hand size to gun grip b/c the reach of trigger finger to trigger does increase almost imperceptively (duh as photo suggests). Ergo, some may have a perfect grip to hand fit and might not adjust to this extra reach this laser introduces. Other may wish to have a bit more reach and this could be teh perfect answer ... since Gen3 comes with no fancy backstraps to tailor fit.

Try one in a gun store then buy from the best - Optics Planet, always puts a smile on your face!
