The Walther PPQ 45 is another variant in an already versatile PPQ family. Compared to its root model, the PPQ 45 is enlarged to accommodate a 45 ACP cartridge. Unlike the 9mm & 40 S&W chambered models, the PPQ 45 features polygonal rifling. It has a 4.25" long barrel, an overall length of 7.4", and weighs roughly 28 oz. Although a bit heavier and enlarged compared to the rest of the family, the PPQ 45 provides an excellent feel while shooting, retaining accuracy and reliability, which is what the whole PPQ series is renowned for.
