American National Firearms recoil spring for Sig Sauer P250C 9mm. This is a high quality standard strength recoil spring for the guide rod in your Sig Sauer P250C (Compact) 9mm. If your P250C 9mm has the spring that slides on and off the original guide rod, this spring is an exact, drop-in equivalent for your original. If you have the plastic guide rod with ""captured"" spring (the spring does not slide on and off), you can now enhance your gun using this spring and one of our solid stainless steel guide. This recoil spring is for the Sig P250C in 9mm only. It will not fit the P250C chambered in .45, the P250 Sub-Compact or the P250F (Full Size) in any caliber. **Note: There are two types of guide rods found in this model firearm. One is the traditional style where the spring will slide on and off the rod, and the other is the ""captured spring"" type where the spring does not slide off. Sometimes, one end can break off of the plastic ""captured spring"" guide rod, and the rod will look like a traditional rod with a spring that now slides on and off. Please check to see which guide rod you have before purchase of this spring.
