What sort of sight package you looking for? Tritium night sights? Such as a Novak style?
Some of the cuts in the SA slides are different from model to model. Also, the cut in your TRP made to accommodate the low profile fully adjustable BoMar style sight is further forward than, say, the cut made to accommodate a shrouded Novak ALM03 tritium night site.
My recommendation is to check out BoMar and Novak to see if they have something that fits your TRP with the fully adjustable sight package.
