Interesting.I have been shooting low, like 12" at 50' with 115gr. It is me and this gun. (there has been another thread on shooting low with it, and SW sent the guy lower sights). however, this gun is correct, I have had 3 different people try and they have no problem. I am fairly new, but I am pretty sure I have the fundamentals correct, my sig 22 I have about a 5" group at 50'. I am wondering if I went to heavier bullet if this would change my accuracy?
