Lots of good advice on here about off hand shooting. Foot forward and dont grip the gun to tightly, very good advice. The other little trick I use is I dont try to hold the crosshairs directly on the target for very long. I hold them slightly below and creep the crosshairs up to the target and squeeze the trigger when they get to where I want to shoot. This might not work for you, but it does for me. My great uncle taught me that when I was a young boy. He was one of the finest offhand shooters I have ever seen. Dont forget practice practice and more practice. I am not anywhere near as good as I use to be because I dont practice like I should. I always try to get a rest first.
