Another vote for the Crimson Trace. Have the laser grips in my Kimber Ultra, and one on my Ruger LCP. Both are effective in less than bright sun light, easy to sight in, and hold their sight settings. About a year and a half, 1500 rounds on the Kimber, and the same with maybe 300 rounds in the Ruger with no issues, and still the original batteries. I have not seen a laser yet that is truly effective outdoors in bright sun light. With the Lasermax, the guide rod model is not adjustable to your sights, and the model that attaches to the Picatinny mount under your barrel requires a special holster. The Crimson Trace model snaps onto the backstrap of your grip, allowing you to use most normal holsters, and is activated instinctively with your fingers when you squeeze the grip.
