Bernhard Müller designed this locked-breech pistol in 1902, seemingly a hybrid of the Luger and P38 (of course, the P38 did not exist at that time). It appears to use a modified Luger magazine and is chambered for the 7.65mm Luger cartridge. The grip is very much Luger-like, in part because the use of a Luger magazine requires using the same grip angle as the Luger. The pistol is a short recoil action with a pivoting locking block much like what the P38 would later use. It is a very comfortable gun in the hand, but was rejected in Swiss pistol trials.
