I recently jumped on the CZ bandwagon with a CZ Shadow 2 and its quickly becoming my favorite. My suppressed MP5 clone (PTR 9c) goes with me almost every trip too.
Never shot a 1911 until 4 years ago and never understood what all the fascination was about them? Wow, was I pleasantly surprised by my ignorance! Those 586's are hard to find, been looking for a nice 4" for quite awhile! Hang on to yours...
pistol is definitely M&P22c with a gemtech can on the end. I can hit pretty much whatever I want without concentrating on aiming at this point, at normal pistol distances.
rifle is still mini 30. big round really rings the steel, and is accurate enough out to 200 yds to consistently hit targets.
both I can afford to shoot all day too.
honorable mention is the 10/22. with the tac sol barrel I can shoot 1 inch at 50 yards.
My police trade-in Smith M64. Best-shooting gun I have. Smooooth DA trigger. She ain't the purtiest girl at the dance, but she's the one you want to marry.
My two favorite. These may be controversial to some:
Rock Island Armory Ultra Tac 9mm.
This pistol is a chunk. All metal, and heavy. Shooting 9mm out of this makes the recoil feel like shooting a .22. I'm a terrible pistols hooter, but this pistol makes me accurate!
A K38 swiss straight pull is a really nice bolt gun. On the more different side.
Other than that shorty 10 in SBR/pistol AR's are fun.
Mostly it would have to be situation dependant wouldn't it?
Edit: Unless it's a trick question. Then the answer is obviously any High Point!
