It all seems to boil down to semantics. But, regardless of the "realities" of either word, it seems generally accepted that there is a true distinction between "revolvers" and "pistols". If I went into a gun shop and asked to see their selection of "pistols", I doubt they would break out the revolvers. If, on the other hand, I asked to see their "revolvers", they probably would not break out the 1911's, Sigs, Glocks, XD's, etc., etc. Now, if I asked to see their selection of "handguns", they would probably ask me whether or not I was looking for a revolver or a pistol. You get the idea...
So, I will base my poll response on current distinctions, whether mis-guided or not.....
