The trigger guard would have to be replaced along with the buttstock for certain. And, the long tang on the straight grip is so pretty I'd likely have second thoughts about getting rid of it.
Actually, I can shoot a straight-hand stocked .410 just fine. But, when I get into the larger bores where recoil becomes significant I just can't manage the recoil as well as I can with a pistol grip. I've got a beautiful, re-stocked, 32" barreled Phila. Fox A grade that has a straight grip and I just never shoot it. Tried using it one year at the NSCA GA State Championship, in the Main Event, and it was a disaster. Even with 1 1/8 oz. loads I can't manage the recoil as well. I don't know how Mistah Nash did it with 1 3/8 - 1 5/8 oz. loads in Bo Whoop. I just have to say he was a better man than me.
