Sig Sauer P228 P229 Locking Block Insert Phosphated, 1202381-R

Description

Restore rock-solid barrel lockup and slide timing in your Sig P228 & P229 with the Sig Sauer OEM Locking Block Insert (Part# 1202381-R) from NDZ Performance. This factory replacement insert is phosphate-coated for corrosion resistance and engineered to Sig tolerances so your pistol returns to original fit, function, and service life. The locking block insert controls how the barrel cams and locks into the slide. A worn, gouged, or corroded insert leads to poor lockup, inconsistent headspace, increased wear on mating parts, and reduced reliability. Replace worn components with the correct OEM insert to preserve safe, repeatable operation. Get yours at NDZ Performance today!
