I may just call CSMC for some technical help. If they have a curved version of the Silvers in stock I will go with that.
Thanks to all for your input. The project is moving along and I'm having a great time working on this shotgun. I'm glad I am starting now since I may use it on the dove opener at the end of the summer.

Thanks again for all of the great input - Kyle

Kyle:
For the butt pad there is one other alternative. Buy a repro Parker plate of the correct size from NC Ordnance. Fit this plate to your gun. Then sand the back of the repro plate flat on a sander. Epoxy the Glalzan pad to this curved "base", shape and finish the pad as others have described, and your set. No need to bend the Galazan pad as the repro pad is already curved. The original plate can always be re-installed.

Best, Kensal

Kensal -

Thanks, that's a good idea. So I guess you mount this plate first, then epoxy the pad onto it? I'm trying to think through how the screw holes in the pad would work.

Thanks again - Kyle
