Comparing John Moses Browning's two most successful .32 caliber pocket pistol designs is like night and day.
The Colt 1903, save for its simpler blowback method of operation, is very like a scaled down version of one of his larger, short recoil-operated pistols. It has a familiar arrangement of hammer, sear, and disconnector, operated by a sliding trigger, all of them, along with the grip safety, tensioned by a three-fingered spring.
The FN 1910, on the other hand, is a scaled-up FN 1906 Vest Pocket .25, all the way down to its pivoting trigger and coil-spring-powered striker. Despite having handled and fired numerous 1910's before, I had never really noticed that, probably because at the time I didn't have a lot of hands-on experience with the smaller .25's.
The strange part is that the Colt Pocket Hammerless, despite being the physically larger of the two, feels a lot smaller in the hand. The grip feels much slimmer, and the whole gun has a rounded, "bar-of-soap" feeling that makes it so amenable to being slipped into a topcoat pocket. The FN 1910, meanwhile, actually feels bigger than it is; the squared-off grip has a chunky, hand-filling feeling that reminds one that this gun was far more likely to end up in official flap holsters than in civilian coat pockets.
On the other hand, holding a 1910, you now know the answer to "What gun for Archdukes?"
I need to get them side-by-side on the range...
