I haven't seen any posts about these guns. I have tried a standard search of this web site and have, pardon the pun, come up dry. They were introduced by EMF a number of years ago through the influence, from what I learned, of John Bianchi. They are considered by the ATF as a non gun. I thought they were a great idea: dry fire with a dummy gun for practice. Practice your spinning with a DG and don't worry about dropping it. If I'm not mistaken, these were only available for a few years. They are exact replicas of the steel SAA's that pietta makes. I two: a 5 1/2" blue CH, and a 4 3/4" blue CH model. My son has a 7 1/2" nickel model.
Are any other members familiar with this variation?
