Beautiful collection. I wondered whether you purchased the blued GP100 or the stainless -now I know! Love the square-backed trigger guard on the Blackhawk. Mine has the rounded one but the square is very distinctive. Mine also has a fluted cylinder -yours is more like the traditional B.H.. Sweet pearlized grips too.
If I were you, I'd keep the Texan. Some guns are just fun to own and this one might be missed if you part ways too soon. Just a thought.
Somebody -is this Blackhawk a coveted older three-screw model?
