Ran into what I think is a SA Loaded stainless model at my LGS. It has the rear full adjustable sight, skeletonized hammer, extended beavertail, trigger with holes, flush mags, ambidextrious safety and wood checkered grips. It is rollmarked in US. I know its not a mil-spec or RO. Pretty sure it is a loaded model and it is preowned but never fired. All of the original packaging is included. Price my gun guy has on it is $750 but I'll do a bit better than that on it. I would trade off my RIA and pay the balance in cash. Is the $750 fair?
