Jake-
As you probably know, there was an article in DGJ back in 00 or 01, which covered the development of the Caprinus and subseqently the Flodman gun. While the article is an excellent starting point, it left me with as about as many questions as I started out with...All that being said, I own a caprinus, 27 3/4" barrels, black chromed stainless barrels, weight about 8 lbs.
It is a very well made gun, with a very interesting design- all stainless steel construction, strikers are inline much like a rifles firing pin and uses coil springs, and the gun cocks by the opening of the lever versus the normal way by opening of the action. The gun has selective ejectors that somehow bleed off gas from the chamber to function. There is a very small removable plug in each chamber which when removed, allows gas into the ejector area-I am still not exactly sure how this works and it is not covered in the original owners manual that came with the gun. So if anyone else knows can explain this I would greatly appreciate it!
I hope this helped out! If you find out more info, please post it here as there is very little information out there on these guns!

Most here don't want shallow- actioned O/U SS gun with direct strikers (lock time 2/1000 of a second!). They want pieces well past "best if used by date" capable of digesting 5-6KPSI loads.
