Crimson trace light guard, glock 17, 23 or others - Crimson Trace Light Guard, All Compact and Full Size, Fits Glocks

Bought this light for a Glock 23 concealed carry. It will also fit my Glock 17 and many other Glock models. The fit is PERFECT and the switch is in the ideal position. I haven't used the light at night yet but it seems VERY bright. If you look into it (before you install on pistol!) and tap the button to turn it on you will be seeing spots for a few minutes. This alone makes it good for defense. Crimson Trace is advertising free batteries for life on their website but that offer is not valid on this battery size. Now I'm searching for the perfect IWB holster. BTW, I replaced the front sight with a Dawson Precision fiber optic sight. Nice.
