I was choosing a handgun over the summer, was seriously considering the glock, usp, and sig p226 .45 cal. After shooting all three quite a bit, I decided to go with the sig. It was easier to use, maintain, and shoot than the other guns. And it was by far more accurate, to me, than any of the other guns.
Actually, the gun I thought I would like the most, I liked the least, and that was the glock. Its not an inherently inaccurate gun, but it seemed to be more difficult to shoot due to the safety being right on the trigger. Far stiffer trigger pull than the other 2. The usp was bad ass, but I was looking for something with a little more power. So I ended up getting a sig. Its very fun to shoot, and I use it all the time right before finals at the shooting range.
