What is the most accurate 9mm pistol?

Answer 1

Out of the box, most of your quality brands (Sig, H&K, S&W, etc.) are going to be on par with each other. H&K claims their USP pistols are the most accurate out of the box, but it's been found debatable. If you're just looking for a basic self defence handgun, the differences will likely be negligible. If you're looking for an actual target pistol, and are going to shoot expensive target loads through it, the Sig P210 is - if not the absolute best choice - among the best choices.
