nitro when you say limited interest,i believe that just because of its size and soon to be ledgendary prowess talked up that the interest will be huge,big boys toys syndrome type of stuff.My mate in Texas has a 454 casull and he tells me that 20 shots is enough with sore wrists and always a headache(muffed up yes) he will probably get one of these 50`s and let me know about it too,cant see why someone hasnt made a 50cal bmg contender type of handgun--now that would be fun stuff i reckon for the big boys.
