Well, I can't force people to be right but, IMO ...“Best handgun” is just an opinion.
Glock 19,17,20,21,22,34,35, maybe 30,26,27 (if under a 10 round limit)
Maybe a 1911 (beavertail grip safety and decent sights are non-negotiable)
Maybe a Sig 365 or Hellcat (especially if under a 10 round limit)
Snub revolver? As a "back-up" okay. As a primary? No*
*If one is uncomfortable with loaded chamber on a pistol or operation of a pistol, then Yes.
