ISMI Trigger Spring for Sig Sauer P320 Plus 10 Percent

Fits Sig Sauer Models: P320.

Tighten your Sig P320’s trigger reset and improve follow-up shot speed with a precision +10% ISMI trigger spring available at NDZ Performance. Built from aerospace-grade chrome-silicon and finished with motorsport-level processing, this spring increases rearward reset force for a crisper, more positive, reset and longer service life versus stock music-wire springs. Find the best components to upgrade or repair your Sig Sauer pistol at NDZ Performance.

Features:

• Cleaner, more positive reset: +10% force reduces mush and gives a faster, more consistent reset for better follow-ups.
• Stable, long-life performance: Chrome-silicon construction resists relaxation and holds tolerances far longer than music-wire springs.
• Precision manufacturing: Heat-treated, shot-peened, and stress-relieved after winding for predictable compression and longevity.
• Ideal use cases: Range, competition, or precision builds where quicker, crisper reset is desired.
