Need Hammer for Springfield 511 SxS shotgun

we found out that we have a broken hammer on the right side of our Springfield 511 12GA SxS shotgun. It is broken acrossed the piviot shaft hole. the crack look like the material may have, some kind of cast in the steel. it does not appear to be solid steel. on the forward side of the piviot hole it looked older crack and on the rear side it looked more fresh, but very close in color of the two cracks..

any way we need a hammer for the right side of the shotgun.. Where can we find this part? Does savage still have them?? What else fits?? Is 20Ga 511 the same also.

Should we replace both sides..

we was out of time last night and found only one place that handle, i think an aftermarket hammer but was out of stock for the right side hammer but had the left..

Does someone make a better material hammer to replace?

Any advise would be helpful thank you stano

I should add that the shotgun appears to be used very little and was real clean under the stock.. but not any oil or lub on the parts..
