Detailed Description


This high quality SIG P320/WCP320 guide rod is precision machined from hardened stainless steel with a bead blasted finish. This rod is profiled to use a full-size 1911 recoil spring so you can easily tune your gun with commonly available springs, to the recoil impulse of your ammunition. 

We recommend a 14# spring for standard velocity/target loads and a 15# spring for standard/+P.

  • Machined from solid stainless steel with a bead blast finish
  • Fits full size 320 models and variants like the WCP320 (Not compatible with X5 models or Carry, Compact or Subcompact models)
  • Uses common 5”, full-size 1911 recoil springs-recommended springs listed below

Great adishon
Easy install dropped right in. Feels much smoother with the Wilson 14 pound spring the the factory spring and guide rod
Works 👍Great
Installed this WC FS SS Guide Rod on my Sig Sauer 320 Full Size 4.7” Pro Cut Slide Assembly with a WC 5” Chrome Silicon 15 lb. Recoil Spring, which I use an EFK Fire Dragon Threaded Barrel in Black Nitrite Barrel with a Legion Precision Compensator. Additionally I use the WC Carry Grip Module, which is Outstanding 👍 Plz. Note: You might have to file just a very small area on the front of the guide rod, to properly dissemble from the slide. EZ to do. Highly Recommend all WC parts.
