It's going to be a curiousity item. It will not be the new wave of technology. I give production another 5-10 years. I am glad you enjoy the firearm but it will IMHO always just have a bit of a cult following and never make it as a mainstream option. I would like to actually shoot one (have only handled them at LGS) because I think it's a cool novelty.
It's is almost scary when people form firm opinions without factual basis...
YOU HAVE NOT YET FIRED THE GUN...!!! (It was Mikey in the Commercial that said "Try it... you'll like it...")
This design is all about the physics that takes place when you touch off a cartridge... You HAVE to actually shoot the gun...
People that totally lacked first hand experiences said the same thing about the telephone, light bulb, airplane, cell phone, automobile, rubber tire and even the home refrigerator... just to name a few major innovations... Even the first repeating rifles were considered a fad (except by those that used them)...
You really have to take a traditional Snubbie and a Rhino, load them with the same 357 ammo and then shoot them one after the other... From a "weapon effectiveness" standpoint it is like comparing a "club" to a "crossbow"... (and I'm sure the first crossbow had it's naysayers too)...
Every person that has expressed the opinion that you have, has done a complete 180 after firing a box through my Rhino... and shooting their first five shot quarter sized group from a snubbie...
