The Colt 1903/1908 pocket pistols have serious disadvantages for carry guns, aside from the fact that they are single action. The worst are the small safety, easily missed in a crisis, and the tiny sights, almost useless anywhere but a well lighted range. They are also an awkward size; too big to be easily concealed or slipped into a pocket, too small to have really effective power.
Some time back, a poster showed the M1908 he had built for himself, with many changes in sights, safeties, slide serrations, and so on. Nice ideas, but it was NOT an M1908 any more.
But I still like them.
