Really nice! I own two at this time, one 4" blue and a 4" stainless---both with the older barrel profile---in my opinion, your version is the best of the Security Sixs---just my two cents...
Thy came out with the 4" HB for the texas rangers, Thy ordered 500 guns. Then thy make them for US. I Got one way back then. It is A real shooter.My SN. is 158-17xxx
