In terms of subguns, Ive never really liked the full size Uzi, its controls are awkward and the blocky open bolt design makes if far less ergonomic than other open bolt guns like the MP40 or Sterling. I prefer closed bolts like the MP5, or quite frankly, in a purely tactical sense as an armed civilian, you are better off with a basic 14 inch M4 or even, if you live in the country, a shorty FAL, semi auto is fine.
