Thanks everyone for your replies. I believe I have enough references to get this gun fitted right. LOP needs to be shortened, and as long as I am doing that, I might as well have it fully fitted to me. I should say, I am not a green beginner. I have been shooting a semi Benelli several times a month for a year, but I am new to O/U world. I can play around with the Benelli to get it to fit right, but the Browning O/U is a different animal, and needs a professional.
Again, Thanks everyone.
