As further followup: Left my sunglasses at the range. We had to go get them, so we shot both days this weekend. That's about 500 rounds through the MkIII over the two days without doing an initial cleaning. At the end of the second day we were getting failures to feed with exactly the same ammo we started with. So, I brought the MkIII home, disassembled it, cleaned it, and reassembled it for the very first time.
With the right tools, disassembly is easy. It's a clever design and the only thing tough was how tight the initial pin is to get out. A rubber mallet really helped.
Reassembly is definitely tricky. Getting the hammer positioned just right on the final step was not clear to me from the manufacturer video. In the end, this video was the one that really helped me with reassembly:
Fun gun. Not a serious business kind of thing, but I can say that alternating between this and other guns is making me a better shooter. When all the shots from the Ruger go into the center of the target, and the shots from the smith are going down and left; it's pretty clear that how I pull the trigger on the smith is moving the gun.
