A great help - Crimson Trace G-Series Full Size Glock Laser Grip

It works great indoors. Outdoors it is still very good except in direct, very bright sunlight and on certain materials where the laser dot does not show well. As this is my first laser sight, I guess this is to expected. All in all I am very happy with the sight. I use a Glock 17 and am getting to be very accurate out to 20-30 yards. It is also allowing me to work on my steadiness of hand, breathing, etc. so that the sight stays on target. This is a boon to all of my shooting including with other open sights. Because of the way it mounts, I can use all of my old holsters as well.
Pros: It really helps keep me on tagrget
Cons: Adjustments are very sensitive
