Mauser Model 1914, a vintage WW1 era semi-automatic handgun used by the German Empire. It's chambered in the 7.65 mm Browning Short (or .32 ACP) cartridge.
I made this in about 5 days, completely smashing it out during the weekend. Proportions may not be 100%, since I only have 2D reference images to model from.
