American National Firearms solid black stainless steel guide rod and springs for the Sig Sauer P220, P226 and P227 series pistols with standard length barrel. When using a solid rod, there is greater mass at the front of the gun to resist a change of motion when shooting (inertia), which helps to tame recoil and get your sights back on target quickly. With this decrease in muzzle flip, follow up shots can be placed swiftly and with more accuracy, while the moderation of felt recoil translates to a reduction in shooter fatigue. In short, the competitor will shoot more quickly, more accurately and for a longer duration before fatigue and shaking begin to interfere with performance. Tough MIL-SPEC stainless steel ensures long term durability; the guide rod will not chip or break. Part includes one 15lb. and one 20lb. Spring to accommodate all calibers. This guide rod fits the Sig Sauer P220, P226 and P227 pistols with the standard 4.4 inch barrel. It does not fit the X5/X6, Carry models, P320, models with the 3.9"" barrel or models with the 22lr conversion.
