1-3/4"  OAL Here is my long promised 5-shot, 2mm, pinfire, pepperbox.  I've had the cast frames for over a year,  but have waited to release this model until I figured out how to index the barrel.  After several designs,  I went for the simplest approach and use the screw-on barrel lock to hold the barrel in place. 
The frame, bar hammer and ring trigger are all  nickle plated cast brass.  The barrel, which is removed for loading,  is steel, which I plumb-brown to give it a nice antique look.  So far I've only made this gun with Ironwood grips.  This is a hard wood from the deserts of Arizona, which  has a tight grain and  takes an excellent high polish.  I can also make this gun with any of the other grip materials found on my other guns,  but the ironwood with the plumb-brown barrel contrasts nicely with the nickel frame and makes for a beautiful mini.
