autos, and pumps have an additional 6 ins in length as far as the sighting plane when they are quoted as having a 28 in barrel. So your used to that extra length not there in O/U
So a 28 in O/U is pretty short. Best choice unless a lot of target then longer
Athena (SKB) if you can find one.
Beretta always good
Citori bigger action not as slim , but good gun.
