The decision to use a striker vs. that of an internal hammer like on the
Walther Model 8 was to reduce overall size of the gun, but sacrificed reliability. If the striker spring is compressed for extended periods of time it can weaken and not have enough force to ignite the primer causing a misfire. This can be avoided by not keeping the pistol cocked when not in use. It has a six-round detachable box magazine. The Model 9 is similar in size and function to the
Baby Browning pistol which is only slightly larger. The Browning is also chambered in the .25 ACP cartridge. During
World War II, thousands of the Model 9 pistols were delivered to the
Wehrmacht. == References ==
