My buddy has an AK, I never wanted one until I shot one in real life. If I got a pistol it would be something similar to a Glock .40. A .22 pistol is very inaccurate and doesn't have much power at all, I think of them as glorified BB guns. lol. but for a good all around gun get a shotgun like a mossberg or remington pump, there are tuns of custom parts for them like stocks and pumps, and you have different choices in shells, Birdshot, Buckshot, Slugs(my favorite).
An AR-15 would be a nice gun too though it is the new trend in hunting rifles
Remington R-15
