Streamlight tlr-4 one year review - Streamlight TLR-4 Rail Mounted Laser Sight and Flashlight

Okay, I've now owned my TLR-4 Streamlight light/laser for a year. In the past year I've shot 1000+ rounds out of my Glock 34 gen4 MOS with not one issue. The laser was pretty well sighted in right out of the box and stayed sighted in for this entire year, never having to re-sight, even once! I'm using my G34 9mm for home defense, as I've found the 125 lumen output of the TLR-4 more than adequate as a stand alone flashlight. I use it as a flashlight and laser at the same time for my nightstand security, though it can be used as a flashlight alone, laser alone, or both together. The power switch is in the perfect location, right in front of the trigger. The selecter switch is below the power switch. It's not in a convenient location which is a good thing, as it won't be easily knocked into, changing your light/laser choice in an adrenaline charged emergency situation. The light/laser selection you used last, stays the same, the next time it's turned on again. Installation was a breeze on my Glock, but comes with different mounts for different gun brands. Glock has a below barrel "rail". I also have installed on my Glock the Small, small Vortex Viper red dot sight. That sight stays on the gun all the time. The TLR-4 comes off easy enough when I shoot at the range, and goes on again easy enough, when I get home, while maintaining it's "zero".
