I enjoy weekly informal tactical matches at our local range. There was a noticeable improvement in my shooting, when I switched from iron sights to a Crimson Trace Lasergrip sight. I was already using one on my Glock 26 and added one to my Ruger MK III. It is bright, dependable. Optics Planet.com sells it for less than I could buy it elsewhere.
Pros: Easy to get on target quickly
Cons: Not for bullseye shooting
