Chambered in 9mm and designed to fit PDP 4.5\" frame models, this 5.1-inch threaded barrel extends sight radius and enhances suppressor compatibility right out of the box. The barrel features polygonal rifling for superior bore engagement, consistent accuracy, and improved durability compared to traditional land-and-groove rifling. Standard 1\/2\"-28 TPI muzzle threads allow the use of a wide range of suppressors, compensators, and muzzle devices. The complete kit includes the threaded barrel, recoil spring, and thread protector, providing everything needed for a straightforward, drop-in installation with no additional components required.\u003c\/p\u003e\n\n\u003ch2\u003eProduct Highlights\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eFits Walther PDP 4.5\" frame models, offering a 5.1-inch barrel length for an extended sight radius and improved downrange performance\u003c\/li\u003e\n  \u003cli\u003ePolygonal rifling delivers consistent accuracy, tight bore engagement, and enhanced barrel longevity across extended range sessions\u003c\/li\u003e\n  \u003cli\u003e1\/2\"-28 TPI muzzle threads provide immediate suppressor-ready versatility for tactical, competition, or personal defense configurations\u003c\/li\u003e\n  \u003cli\u003eComplete kit includes the threaded barrel, recoil spring, and thread protector for a true plug-and-play installation experience\u003c\/li\u003e\n  \u003cli\u003eManufactured by Walther Arms to OEM specifications, ensuring reliable fit, function, and durability within the PDP platform\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eSpecs\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Walther Arms\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCaliber:\u003c\/strong\u003e 9mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBarrel Length:\u003c\/strong\u003e 5.1\"\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRifling Type:\u003c\/strong\u003e Polygonal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Pitch:\u003c\/strong\u003e 1\/2\"-28 TPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Models:\u003c\/strong\u003e Walther PDP 4.5\"\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eKit Includes:\u003c\/strong\u003e Threaded Barrel, Recoil Spring, Thread Protector\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMPN:\u003c\/strong\u003e 2871998\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 723364228469\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cem\u003eDisclaimer: We strive to provide accurate and up-to-date product descriptions, specifications, and images; however, errors or omissions may occasionally occur.
