It's basically an FN Browning 1910 with a lengthened barrel and slide and some foofaraw added to make it lawful to sell after the 1968 GCA, specifically "target" (taller front, adjustable rear) sights, "target" thumbrest grips, and a pinky rest on the magazine to increase the overall height of the pistol.
The 1910/1922 family are very robust, simple, reliable, and FUN pistols. Triggers are reasonably short and crisp but may be a smidge stiff from the factory. Spare mags are relatively easy to find compared to other old European automatics.
Drawbacks? No last-shot slide-lock feature. A reputation for fair-to-middling accuracy due to necessarily loose barrel-to-frame fit; they use Colt Pocket Hammerless type frame-to-barrel lugs rather than a rigidly fixed barrel. They have a grip safety, a thumb safety,
and a magazine disconnect, although the latter is fairly easy to remove. Not the easiest pistol to field-strip due to the odd and typically tightly-fitted barrel bushing. Trigger span is very short and grip safety
must be depressed
firmly in order for pistol to function; this yields an awkward firing grip for those with large hands, because the grip safety naturally falls in the hollow of the palm.
Although my list of drawbacks seems long, don't get me wrong, I really like them.
p.s. Have an original black leather Browning-logo gun rug I'll sell you if you buy the pistol.
