I'm a fan of .22 lr.
If you're looking for 2 gun combos, there are plenty of options.
I have just a few myself:
.45 long Colt = Colt SAA/Winchester Carbine/Uberti Deluxe 1873
9mm =. Marlin Camp 9/any one of my 9mm pistols
.38 spec/.357 mag = Smith revolver/IMI Timberwolf (pump action)/Winchester Carbine
