Ejsxs and GregSy, yes, the 16 gauge barrels on my 1/2 frame DHE fit very well, including pin strike and barrel breech area. Tony and Simmons Gun Specialties should take this into account when advertising their replacement barrels. If interesting combinations of #1 frame barrels are advertised by either gunmaker, the barrels should be suitable for #1/2 frame guns as well as #1 frame guns.
