The Tungsten weighted guide rod recoil spring assembly is more than 4 times heavier than the factory polymer RSA coming in at 2.2oz . This will lead to quicker target re-alignment and more accurate follow-up shots! This 50 Newton RSA is a direct replacement for all PDP, PDP F-Series 4″ and PPQ models. *Will not work with PDP F-Series 3.5″, PPQ 45 or PPQ SC
