Tate uses Poli actions not Siace. Poli had some issues with the internals being a bit soft but according to Tate, he re-hardens and polishes them. A friend recently purchased one in 28 and we shot it a few weeks ago. It was a very nice gun, but one of the hammers was much stiffer then the other and kept piercing the primer so he had to send it back and Tate adjusted it. I think the gun cost around $14-15k, so they are a bit pricey. Very nice guns though.
