Was your range session inside or out? I got rid of my Crimson Trace grips because I do most of my shooting outside and the dot was worthless outside. I also recommend plugging or covering the laser opening when you are not using the dot. Mine got dirty pretty easily and the dot wasn't a fine little dot for long. The laser's lenz was pretty hard to clean really well and my dot was never as fine as the first few times I used it. Keep posting, I want to see if you run into any of this or if it was just me.
