Restore crisp, reliable trigger engagement with this replacement trigger bar spring for the SIG Sauer P320 platform. Manufactured from heat-treated spring steel and finished for corrosion resistance, this part replaces worn or damaged springs in the trigger bar assembly to help return trigger and sear components to proper positions and preserve consistent trigger feel. Precision-formed to match factory geometry, it installs directly into P320 fire-control groups and compatible X-Series variants without modification.
Recommended for armorers, gunsmiths, and owners performing maintenance or parts refreshes. Always perform a function and safety check after installation and consult a qualified gunsmith if you are unsure — improper installation can cause malfunctions or unsafe conditions. Not a drop-in replacement for other, non-P320 models unless explicitly specified.
