Well,
I have found that for most people it is more of a preference as to wether or not you will like the lasermax. I bought one and installed it in my glock 27. I found that I was concentrating more on the silly little dot than I was on the target. For me, the dot became more of a distraction while shooting than a help. If you use a point shooting method when engaging targets under 20 yards then you probably won't like the device. The laser will go quite a ways but you lose accuracy over distance. I found that when I bench rested my 27, the laser was close to point of impact but not exact. Good luck with what you choose!
