That 3" barrel and short sight radius does tend to take it out of the bullseye class !!. But it should be easier to shot than the DA trigger on that s&w. No stacking of the trigger. With rounds down range you will get better but nothing much sound wrong with your groups now. Hard to complane much when you look at the size of them. Plus P ammo is easy to shot in them too. Pull a piece of 1.75" bike inner tube on the grip to help with control as round count goes up. There free at bike shops if any are near by.
