ISMI Trigger Spring for Sig Sauer P320 Minus 20 Percent



Designed to fit Sig Sauer Models: P320.

 

Tune your trigger with race-grade hardware. The ISMI Minus-20% Trigger Spring for the Sig Sauer P320 reduces the spring force approximately 20% versus the factory unit to deliver a lighter, crisper trigger feel and faster reset while retaining predictable, repeatable function when installed and tested correctly. A precision replacement trigger spring manufactured from aerospace-grade chrome-silicon alloy. Each spring is heat-treated, shot-peened, and stress-relieved to hold tighter tolerances and deliver long, fatigue-resistant service life compared with music-wire alternatives. Get yours at NDZ Performance today!

 

Features:

  • ~20% lighter spring force: Noticeably reduced trigger effort and a snappier feel.
  • Racing-grade durability: Chrome-silicon construction with heat treat and shot-peen for long life and stable rates.
  • Tighter tolerances: More consistent trigger timing and repeatable feel over thousands of cycles.
  • Direct replacement: Drop-in fitment for P320 trigger housings (confirm model compatibility).

    Posted by Mike on Feb 25th 2022

    After install of this spring, my trigger scale registered as low as 3.5lbs on trigger pull. A 2lb reduction!
