I carry my LC9 daily and just added LaserLyte's side mounted laser. Installation was a snap 5-10 minutes and a rough sight in yesterday so today I took it out back and at a measured 12 yds. this is what happened! The first two shots were off a bit the red dot was hard to see against the red bull. But once I settled down the next five were in the red Needless to say I was pretty happy with the results and the performance of this very light laser sight. I have since fired about 100 rounds and it is still dead on!
