Description
Upgrade your Sig P365 Standard 3.1″ recoil system with the Curated Arms Guide Rod Kit. Each kit includes a precision machined guide rod, a collar for secure fitment, and three flat wire springs sized as part of your chosen spring family. Choose between black coated or stainless finishes to match your pistol. We offer two spring families for fine tuning.
Standard springs come in 14.5, 17, and 18.5 pounds, and follow similar recommendations, with 14.5lb for competition, 17lb for EDC, and 18.5lb for +P.
Function testing is essential after any recoil system change. Reduced spring rates can alter slide velocity and felt recoil, and may require ammo testing for reliable feeding. Kits are intended for range and competition use. As with ANY aftermarket components, if daily carry reliability is a priority, consult a gunsmith and test the combination with your preferred ammunition.
