I'm with Ned-- why take a good, handy, sturdy pistol, and make it ungainly, over-specialized, hard to draw easily or carry easily, and about 189 times more fragile?
I've always hunted my pistols iron-sighted. And, as a matter of fact, I've passed up a BUNCH of shots I could have made, had my pistols had 'scopes on them. Part of the game. My pistols are, however, very handy, very servicible, and, in a high-ride holster, are darned serviceable carry guns.
Will you, too, be one who stands in the gap?
