For me, in rifles, that's an 1898 Lee-Enfield RIC carbine. In shotguns, it's a Winchester Model 1200 w/ 22" slug barrel. In handguns, it's a 5" Smith Model 27. But if you're looking at your first firearm, once again, I would recommend taking a look at a Ruger 10/22 Magnum (something I'm looking for, for myself, right now ;>)...
My wife had never shot a handgun until I started training her on the HK4 (with .380 barrel installed) for her Texas CHL. When it lost its (oil-damaged Delrin) recoil buffer, I handed her my P7M8.
To make a long story short, she shot within 10 points of perfect with it on the CHL test. Then she nearly gave me a heart attack when she called my son that night and told him she really liked the P7... (Have you priced one of those things lately?) '-)

Yep, the 10/22 mag would be nice -- but my trusty old (1967 model) 22LR 10/22 still does a fine job -- even after my son converted it to a folding-stock "assault weapon" with all sorts of aftermarket stuff...
