I took a trip to the range today, and discovered something I had not figured out before. I noticed that the first couple groups were way off, and figured out that I was leaning back when firing. I never noticed this before. As soon as I got a better stance and stood strait, my groups improved alot. I also rented a G17, and it was the first pistol I have ever shot besides my Sig .22. I put 50 rounds through the glock, and about 300 through the sig. Below are my groups with the glock and my best groups with the sig. I think I did just as well if not better with the glock than the sig. Groups at 7 yards.
