Package Includes: 24# Flat-Wire Recoil Spring FAQ 1) Is the flat wire spring compatible with a full length guide rod? Yes-Only with the full length flat wire guide rod (#25GRFW). The inner diameter of the flat wire spring is smaller than a conventional round wire spring requiring a flat wire specific guide rod. 2) Is a Shok Buff required? A Shok-Buff is included but optional on the 5” flatwire guide rod. It is not recommended for use on the 4” kit since it can reduce slide travel. 3) Can I shoot +P ammunition with this kit? Yes-since flat wire springs don’t lose their length over time like round wire springs they cushion your frame more effectively over time. Flat wire springs also compress in a more linear fashion which makes them more tolerant of a wider variety of loads and grips. Payment: We handle all payments through Paypal.
