That is correct...Roger Hunziker sometimes drove down from Huntsville to my gun store in Conroe (Shooter's Station) to try to convince me to stock his creation...An employee of his was also a regular customer and still a friend, who showed me how the gun worked...I never bought any because I just didn't think the market existed for them...I did however transfer several of them to his customers, and each was shot on my range using various calibers...All were successful in function, although accuracy was questionable from caliber to caliber...The weak point of the design in my opinion was the little 90 degree "fingers" that held the rimless calibers. Fired rounds could sometimes stick in the cylinder and if you forced them out you could break the "fingers" (ask me how I know this).
My 20+ year memory is as hazy as my pre-cataract surgery vision was, but I do recall Roger mentioning that .380 reliability was an ongoing concern from one brand to another...I don't remember any mention of .38 S&W, but I doubt that it would have chambered at all because of case diameter...I have no contact information for Roger, but I do occasionally see a former associate of his, and I will ask about his current whereabouts and welfare next time I run up on him...I got to shoot one just as in BB's photo, with different kinds of ammo. It worked pretty much as advertised, just misfiring sometimes with the .380 cartridge.
