Why isn't there no “why” in the real world?Nobody is going to make one. There is no "why" in the real world, but 95% of all talk on guns could be reduced to get a Glock, a 30-06, and a few other things. Oddly, there seems to be a small fetish out there for creating doubles that are impractical. Ever see the 1911 .45 double? Would it have a tactical purpose, sure, the idea I mentioned of two immediate shots and the most rapid reloads one can have short of an automated system is a useful thing. But then, is it a step forward to give hunters a better gun? If so, a local shop seems to have cornered the market of 9.3x62 barrels for the Garand.
