A few months ago I scored an older 1100 at the local pawn shop.
I got it home, disassembled it and gave it a good cleaning. The recoil spring and tube was REALLY crudded up and probably would have caused the gun to malfunction it was so bad.
I took it out shooting and like it's legacy, its a soft shooter.
I also replaced the plastic butt plate with a rubber recoil pad to reduce sliding on the shoulder and comfort of shooting.
