thanks much for the information Pete and Robert. Robert, I am interested in your comments on the late Husky's. What I am looking for is a 3" chamber for waterfowling. Mainly looking for 3" right now since I have so many shells. Might look at getting a 2 3/4" bored out if enough metal in the barrels. 28"-30" barrel length, straight or pistol greip, double trigger, 12 gauge. Also, how to tell an early model 310E? Thanks for the help, as always the good folks here come thru
