ISMI Sig Sauer P365 10 Round Magazine Spring Plus 5%
Get consistent, reliable, feeding to your Sig P365 pistol where it matters most. The ISMI +5% magazine spring available at NDZ Performance increases upward force just enough to improve presentation on worn mags or when running mild extensions; without over-stressing the system. Find the best components to repair or upgrade your Sig P365 at NDZ Performance.
Features:
- +5% extra power: Compensates for follower travel changes and worn springs while avoiding excessive muzzle-dip.
- Aerospace chrome-silicon: Higher yield strength than music-wire; holds tolerances and spring force far longer.
- Motorsport-grade processing: Heat treated, shot-peened, and stress relieved for minimal relaxation and long service life.
- Cleaner, more consistent feeding: Designed to reduce misfeeds and stovepipes in extended or high-use setups.
