Still searching.
After all one gun for the tropics and another for blacktie or winter wear eh? A gentlemen chooses his apparel with attention to detail, panache and a certain reflection of his character and mood. Thusly, an ill tempered thug may oafishly stuff a chromed "nine" into his oversized trousers, only to find himself fishing in his pocket for a cocked and locked "gat" which is now pointing at his wedding tackle. Whereas a gentleman, with a selection of weapon and properly fitted holster may easily dispatach his foes with outmost haste. Alas, as a gentleman one should never opt for brown leather after 6pm, however oxblood or similar "cordovan" may pass in all but the highest of social circles.
Let us face the fact that breaking bread with Alaskans in a rural setting one may wish to carry more than his customary PPK, say a well worn heavy magnum revolver or meat axe. Whereas such rustic charms are wasted on high society where discretion is the better part of valour, a Seecamp nestled under the cumberbun will suffice.
As to the droll fad the average working man must suffer (casual friday), I would suggest that this does NOT mean showing up at the office in your bath robe with the grip of a Colt SAA sticking out of a terrycloth pocket. Nay, while chinos are frowned upon by this writer outside the tropics, they do allow a certain amount of pocket room where one may stash his weapon du jour.
In essence, a man's taste in firearms may vary as does his taste in shoes or neckties. Staying fashionably "strapped" a gentleman stays ahead of his game, and prepared for any necessity.
