LOL Now you have the picture. True confessions come next, complete with big, bad fed waiting for his own stiches

:foot:
One Detroit copper, a really good guy and local folk hero, Buddah by name decided what he really needed for raids was a double barrel pistol in 12 guage. Serious surgery was done to said 12 guage, the result being about 20? (to 26") long. On the first shot it rang his chimes with gusto...Thereafter he learned to put his left hand over the barrel and lock his elbow for control. I can still see my friend loading it, shrugging his shoulders a couple times, and rolling his neck around just before kicking in the first door. As luck would have it, we did have a firefight complete with two thunderous booms. While the shooting continued unabated, Buddah stood there momentarily, realizing that the only thing between him and the bad guys was an empty gun. Azzholes an' elbows over the couch......and a few days later it was sold.
How could our Hero have gotten it wrong? Surely there was a good concept waiting to be refined?......Off to a local gun show, where a high dollar Browning S-S with some dings became MY test bed. First, shorten the barrels but not the stock (the whole thing came in 3 1/2" shorter than a 30/30, and right at 5 pounds). Second, quick reloading would be accomplished using a small leather skeet pouch. Several boxes of skeet loads were grabbed, and off to the club, where the NEW "Roadwarrior Special" proved astoundingly effectice on clay pigeons. Chest swelled, big grin, let's go kick some doper butt.
After pulling on the bulletproof vest, I rummaged around and came up with 3" Magnum Buckshot. (You see where this is going don't you?) Once inside, a guy pops a shot at me, and jumps back around the corner into the kitchen. I quickly aimed at a spot about 3' from the edge of the doorway and let loose with BOTH BARRELS. Shit, how'd I do that?...It was a single trigger gun! Two holes in the wall, one over the other! Blood running down my forehead, I quickly reloaded...at least that was easy! I figured to fire one more to flush the guy who was not listening to the screams for him to give it up. BA-BLAM! Another double discharge and now my head really hurt!! The defendant gave it up, the kitchen refrigerator was VERY dead, and yours truly began the wait for medical attention.
Post Mortem: The Brownings single selective trigger was recoil activated to prepare the second barrel to fire. Cut a third of the weight out of the gun, make it really whippy, add the 3" Magnum shells....et voila! A gun guaranteed to fire twice on each single pull of the trigger. A dentist bought the gun to use with light skeet loads. When, on this forum, I say something like "i'm pretty sure that won't work".....I try not to mislead you all.
