Not familiar with ASM doubles (In fact was only dimly aware that they MADE doubles...). But not all their productions are mediocre; for a while they were making the best of the SAA clones. I had an ASM .38-40 SAA clone that was more accurate than any Colt SAA I ever fired (including my "New Frontier") and would interchange all but the hand-fitted parts with any genyoowine Colt First or Second Generation SAA. Handsome devil, too.
