I have a 20 gauge 1100 that was a birthday present 46 years ago. I took good care of it and it still runs 100%. Stock is still in good shape. The shotgun has a 28" modified choke plain barrel. My wife is a smallish person and is really not up to a 12 gauge 870. My plan is to have the barrel shortened to 18" and have the bead reinstalled. I'm thinking installing a recoil pad for her and shortening length of pull about an inch including the pad will also be helpful. It will be kept full of 2 3/4" # 3 buckshot. I'm not here all the time, we live out in the country. There's about a 1/4 mile lane from the road to our house and vehicles are not seen from the road. We have 7 dogs and they function very well as a motion detector alert system, be it a deer or anyone coming up the driveway I want to have something here she can use. She is a former competitive trap shooter and totally comfortable with firearms. I feel like I owe this to her. Thoughts, comments, suggestions?
