What do you want from your laser? Is it to help with fast, close in shooting? The Crimson Trace laser grip for my beretta came zeroed at 50 feet, but I found that it didn't help much at that range. I put the laser grips on my 92FS for one reason, to help me shoot the gun in the dark, since it doesn't have night sights. Since my main concern is from my bed to the door, or from the door down the hall, the longest shot I have to worry about is roughly 30 feet.
I zeroed the laser at 21 feet. Inside of the 21 feet, POI is up and to the left, but not by more than an inch and a half. Out past 21 feet POI moves down and to the right, but not enough for me to worry at the distance I intend to shoot it.
