As I train with pistol I am noticing I am getting sloppy, especially beyond 10 yards, groups opening and pulling shots low and left. I don't recall having this much trouble; but then, it's probably been an incrementally slippery slope. This time of year being what it is I don't have the greenbacks for a class, so I am thinking about getting a laser (I think it is a trigger control issue, not a sight picture issue, but I don't know). Would this be helpful, and what type of laser/trainer to get?
