What a useful piece of hardware to hang off your pistol. I'm Mr. Shakes-a-lot, so the dot hops around the target like a mexican jumping bean on a hot skillet, but I found it's not a show-stopper. I'm learning to squeeze the trigger as the dot is crossing the intended POI. I learned that trick bowhunting and figured I'd give it a try with the CT on the M&P. I had several bullseye's at 15 yds and generally kept all my rounds in a paper plate size target. I have to say I'm much more confident after 200rds worth of practice. Now I move out to 25yds and work on that distance. This is getting to be way too much fun...
