My coworker is interested in a shotgun for home defense. Ideally he's looking for a ~ 20" barreled pump (auto is 2nd choice) that can be converted from 12 gauge to 20 gauge. Does such a thing exist?
This is beyond my area of expertise, so I hope someone can provide some guidance. 15 min with Google yielded nothing.
Edit: Just noticed that this is my first post despite 2 years of registered lurking...
I guess I shouldn't worry so much about repeating other folks.
