Wouldn’t it be easier to sell the gun and shop for one that fits you better?
When I was looking for my upland gun I really wanted a Browning O/U but they just didn’t feel right. I tried a few different guns and eventually bought a Beretta Silver Pigeon. It just comes right up inline and felt perfect for me. Wasn’t my first or second choice but sure glad I got it.
Just making a suggestion. Good luck!
