Have not seen one....don't care if I ever do. I am always amazed and put off by the ever present "need" to re-invent the wheel. Innovation is good, by definition - keep blowing out the cobwebs, so to speak. However, this is not real innovation at all. In terms of cartridges and guns, there really is very little in the way of true innovation - mostly just re-hashing that which was already done a long time ago. A .380 revolver.....let alone a 9 x 19 one ? Another 15 oz. pistol (of any type)? Not interested. I'll stick with my good 'ole .38 Special, thank you very much.
