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.
