My Uberti (Cimarron) 2nd Model Dragoon would drop the lever half the time with anything above 35 grains or so of FFF. Filed the notch and never had any more problems. Now shoot 40-43 grains (FFF) all the time with a .454 ball and felt wad and haven't had the lever drop since filing nine years ago. The Dragoon did take two trips to the operating table before I got it right. Considered the spring treatment if filing didn't work, but wasn't needed. Bought a Uberti Transition Dragoon a little over a year ago and so far haven't had the lever drop, even using my 40-43 grain load. Probably jinxed myself, the next time I take it out, it'll probably drop!! You'll like your gun, love shootin mine.
