Enhance your shooting precision with the Walther Tungsten Guide Rod RSA 50N. This tungsten-weighted recoil spring assembly, tipping the scales at over four times the weight of the factory polymer rod, delivers faster target re-alignment and improved follow-up shot accuracy. Designed as a direct replacement for 4” and 5” PPQ and PDP models (9mm and .40 cal), it’s built to reduce muzzle flip and boost control. Weighing in at 2.2 oz., this 50 Newton RSA is a robust upgrade for shooters seeking performance—note it’s not compatible with PPQ 45, PPQ SC, or PDP F-Series 3.5” models
