Have the conversion. Kirst is good company to deal with. when I got it and installed it I noted that it appeared 2 of the chambers did not line up. Spoke with Walt directly, and he had me mail it to him. it was actually how it is designed, as the firing pins are on either side of the latch, so they are off set a touch, but chambers are in line. Fits great in my Navy and one of my Army pistols. my oldest Army is being finicky, so I will play with it. I hope to hit a range in a few weeks. I had hoped it would work in my Dance as well. no such luck there, as the cylinder was in transit I measured and the Dance cylinder is shorter than the Army and Navy cylinders. Either way, the cylinder is currently in my Army with a 3 inch barrel. A lot of weight for a 22, ha.
