I have a Model 3904 (TET53xx), stainless topside/aluminum frame. This particular pistol is Gwinnett (GA) P.D. surplus, with night sights. Lotta anodizing wear on the edge of the tang from the holster thumbstrap, otherwise in fine condition.

Most of the 3904s I see advertised on various lists (e.g Gunbroker, etc) are blue models. Does anyone on this list have any idea what the production breakdown was of stainless v blue 3904s?
