My favorite revolver, and, by far, my favorite handgun overall: Freedom Arms model 83 Premier Grade:
[My recently-retired engineer/scientist father tried to politely change the subject when I explained to him on the phone about a year ago that, unlike any other revolver I had ever held, my then-new Model 83 Premier Grade F.A. in .454 Casull had zero play in the cylinder-none. He obviously didn't believe me, but did not want to argue about it, so he started casually talking about other things. When he came to visit a few months later, he sat on the couch for almost an hour in silence looking it over in amazment and almost disbelief. It truly is a work of art and engineering. It's the closest firearm to a Swiss watch I have ever shot or even held. After firing a couple of hundred full-bore 454 loads through it, there is still zero play in the cylinder--nada.]
Favorite full-sized auto: Glock G20
Favorite compact auto: Sig 232
Favorite really compact auto: Kel-Tec 380 (cheap but is barely bigger than a set of keys [and flatter]; has a 2.7" barrel; has gone boom everytime I have pulled the trigger over the last 8 years; won't hit the side of a barn out past 15 yds, but it's a close-in convenience gun).
