M&H guns are fairly common and not that expensive IF you are willing to take the smaller caliber ones, rather than the big military model. I am still hoping to obtain one of the latter at a price I can afford, but meantime, managed to acquire several in .32 and .38 caliber. They work the same way and I was able to realize why they were not that popular. That loading system is a good example of a feature that sounded good when a salesman said it fast. But the gun is complex, plus it is not that much faster to load than the Colt and a lot slower than an S&W.
