The 4.6-inch steel barrel is threaded 1/2x28 for common 9mm suppressors and features polygonal rifling for consistent bullet seal and easy cleaning. A protector cap is installed to shield the threads when a muzzle device is not in use.
Walther’s Quick Defense trigger gives a crisp 5.6-pound break with a 0.1-inch reset, enabling rapid follow-up shots. The striker-fired action delivers a consistent pull on every round without external safeties beyond the integrated trigger safety.
The slide is milled for optic plates and carries a high-visibility red fiber-optic front sight paired with a fully adjustable black rear sight. Deep front and rear serrations provide solid purchase when manipulating the slide, even with gloved hands.
A reversible push-button magazine release suits both right- and left-handed shooters, while the integral MIL-STD-1913 rail accepts lights or lasers. German CIP “N” nitro proof and Ulm “BI” 2018 marks confirm original German manufacture before import by Walther Arms in Fort Smith, Arkansas.
