I also had an Air Force S&W Model 15 which became inoperable when the ejector rod backed out.
An AMT Hardballer Government Model that I had was effectively a single shot. The first round would fire (using manufacturer suggested Winchester Silvertips), the case would be extracted half way but then stick so tightly it required putting the gun in the vise, putting a dowel down the barrel, and whacking it out with a mallet. Did it every time.
Sent it back to the factory, they sent it back to me "fixed". First round fired, it did the same thing. Got rid of it.
