The threaded barrel is 16 mm (0.6â€) longer than the standard barrel, i.e. the barrel is 118 mm (4.6â€) long. The resulting overall length of PPQ with threaded barrel is 196 mm (7.7â€) and 198 mm (7.8â€) with thread protector. The WALTHER PPQ Navy can be used for submerged firing and for surface use by special ops teams who operate in and around water. The unique features found on the PPQ Navy relate to the firing mechanism. They are not included on any commercial PPQ model.
