Handgun?
I Carry a Ruger LC9 and 2 spare magazines. It doesn't show under normal clothing. I started with a full size CZ-75 though because the weight soaks up the recoil and If I ever have to use my daily carry pistol I won't be too sad about turning an inexpensive little pocket rocket to the police and have a spare.

"Rifle"?
The two I am most comfortable with are my 10.5 in AR "pistol" build and a Keltec RDB
