I think my 9mm Walter M1 as far a handgun and my Remington 308 for a rifle. I use to like my AR but not so much anymore. All of my weapons has a fuction and they perform them well.
My Colt Double Eagle, er my Garand's or Colt 44 mag or LR-308 or whichever one I am shooting at the time. Son and I collect firearms - which is YOUR favorite child?
Love all my CZ's, there's just no reason not to. But I have to say I'm still very fond of my EDC, which is an SR9C I picked up 4 months ago. With the sights adjusted to my liking, it's an inexpensive bull's-eye machine with a fantastic trigger that hasn't had a single hiccup, and I won't sweat it if it gets marked up a bit from being carried.
My favorite handguns to shoot are full sized service pistols, but I am warming up to a SIG P224. For a rifle other than a Garand, I like a Tikka M595 Sporter. For a shotgun, a Winchester Model 12 Riot.
My favorite weapon is my icy cold stare. If that doesn't work, I try squinting a little and gritting my teeth. If both of those fail, I call for my wife.
