Frequently Asked Questions

What is the difference between a Walther HP and a P38?

The Walther HP was the original designation for Walther's military service pistol, known as the Army Pistol (Heerespistole). The German military adopted it in 1939 and designated it the P38. Walther continued to produce the HP for the civilian market, which was essentially the same firearm as the P38 but with a different designation.

Why are Walther HP and P38 pistols in 7.65mm Parabellum rare?

Walther HP and P38 pistols chambered in 7.65mm Parabellum are exceptionally rare because only about 225 were ever produced. This small number was due to the German military's adoption of the 9mm Parabellum as the standard service caliber, making the 7.65mm variants a niche custom order.

What are the advantages of the 7.65mm Parabellum cartridge over 9mm Parabellum?

The 7.65mm Parabellum cartridge offers lighter recoil and a softer shooting experience compared to the 9mm Parabellum. It may also provide slightly better feeding reliability due to its smaller bullet diameter, allowing for a more effective taper into the chamber.

How can you identify a rare 7.65mm Walther HP or P38?

Rare 7.65mm Walther HP and P38 pistols often lack a caliber marking on the roll stamp, as Walther did not have a specific stamp for this rare caliber. Instead, '7.65 mm' was typically hand-engraved. They also feature commercial proof marks like the 'Eagle N' and may have unique features like a large unlocking pin head.
