Pictures of these are scarce, and I didn't take nearly as many as I probably should have. Perhaps later I'll do a good comparison photo study of these next to Ubertis. But the replacement firing pin extension I ordered from Pioneer Gun Works arrived just yesterday, so I snapped some closeups while I replaced the extension.
First, the barrel markings...


Tang...

Carrier markings...

And just some closeup pics of some of the rest of it....



Now here's what I don't understand. The links are a very good fit in the frame and bolt abuttments, but the fit at the center appears to have been deliberately designed to have all the force taken up by the pins alone. Perhaps Miroku is counting on superior metallurgy here, but it is a departure from the original design and is puzzling...

Compare these links....


To the ones from my Uberti....

In other ways, Miroku has made some definite improvements. I checked the front of the carrier lifter, because this area was very rough on my Uberti as received, and I had to polish that one as part of my fluff and buff and to keep the lifter from grinding material off of the hole in the carrier. Moroku's lifter is very round and much smoother. It could probably do with some polishing, but that may come later....

The ramp on the carrier could be smoothed up some as well, but I've left it alone for now...

Here is the other obvious modification Miroku makes--the carrier is slightly relieved on the top left, supposedly to create an angle eject...

This just had to go...

So there you have it; my initial impressions are very positive. The action is smoother than my Uberti was when I first got it. Overall quality is better, but from the pics of originals I've perused, Uberti still makes a closer copy visually. I'll post a range report whenever I'm able to make that happen.
