Urban Rifle
My sister's husband came to me with this exact same question, thinking about a 30-06 Rem 7400, but at the same time concerned about penetration.
Since he doesn't deer hunt, And insisted it must be a rifle even after repeated attempts to talk him into an 870:banghead: he did agree to a pistol-caliber carbine. He ended up buying a Marlin Camp Carbine in 9mm, and he loves it. He had no experience with guns before this; Well , Air Force basic
, but no real experience. My sister grew up shooting, so she took to it easy. Their 11 year old can shoot it quite well, (gets it from his mom!
) , I liked it so much I bought a Kel-Tec in 9mm, my 10 year old likes to shoot it, and does quite well, as has everyone I know who has shot one. I believe the Kel-Tec would fill the bill for you quite nicely. Compact, (foldable for storage), you can pick which pistol mags to use, (Glock, S&W, Berretta), Shoots most anything (don't use Blazers, though, they tend to jam) , just a fun little gun that is very useful, too. A new shooter friend of mine, after trying one, said, " Why doesn't the Army use these?!" He had never shot a rifle before this, and was hitting a 6" steel gong at 50 yds. consitently within 20 rounds!
The Kel-Tec has become my "go to" gun, from woodchucks to "bugging out" this one stays with me! Now to get a S&W 5906 to go with it.....
