This version of an underhammer approaches a sidelock in total parts.
Off the top of my pre-coffee head, there are 12 parts total in the ignition system, including the nipple and various pins, excluding the trigger guard.
In traditional under hammer actions, the trigger guard is the spring, and the parts number is even less.
But it is direct ignition.
Other than that, the big reason it came up is I needed an option for a lefty.
The action itself is fairly new design, (hit "gun works" late last year, IIRC), I haven't seen another gun built on it yet on the web.
