Okay, let me say that the last thing I need is another shotgun. I have plenty of guns and one to do everything. I just want one. I want to set up a little 20 gauge for turkey hunting only. It will never be used for anything else. I have a Win 101 20g that I dove hunt with (and have been using for over 35 years). I am partial to pump guns and O/U because that is what I have always shot. My turkey gun is an 870 Express 12 gauge, 26". I have a good load figured for it and know it will kill birds - all of mine have been taken with it.
I have a youth 870 that I have recently set up for my daughter and have found a very forgiving 30 yard pattern with a factory full and Fed HW #7, but I bought a Trulock for it to get a better pattern if and when she is more experienced and confident in not missing a close bird. It is an absolute blast to shoot.
I have kind of narrowed it down a little. I am thinking a synthetic stock youth 870 - cheap, tough, already have a choke, very comfortable with the 870. Also very interested in a Mossberg Inter SA-20. Another one that has me intrigued is the Weatherby SA-459 Turkey model-the ghost ring sights are a negative-can those be replace with a conventional rear sight? I don't care at all about pretty (I have those guns) and price is an issue since this will be a one use gun (that I really don't need). I like low maintenance.
I definitely want ultra short and ultra light. For no real reason other than to kill a gobbler with a pop-gun when everyone else is carrying a Howitzer. The youth 870 I have for my daughter has me itching for a 20 now. I could just carry hers when she is not with me, but worried the POA will be different with 2 different chokes and I just kinda want my own gun to keep (I am sure her youth will end up with a grandkid one day).
Sorry for the ramble, but this place is so full of smart folks with good advice.
