Friends...want to get an 870 in 20 gauge that will serve as the wife's HD shotty. She is 4'10" so you can tell I will need a smurffy stock! I was preferring a barrel that could use choke tubes in the event she did want to possibly use it to cross over into hunting. What version of the 870 would be a good palce to start and would allow upgrades over time? Thanks. Wanna kill these ads? We can help!
