ISMI 15lb Recoil Spring for Glock Compact ONLY

Designed to fit Glock Models: G19, G23, G25, G32, 38 - Compact ONLY

Tune your compact Glock pistol for consistent cycling and long-term durability with an ISMI recoil spring from NDZ Performance. This 15 lb. recoil spring is a premium, competition-grade, replacement built from motorsport-level materials and engineered for repeatable performance in compact Glock slides. ISMI uses the highest level metallurgy and processes (the same engineering principles used in high-performance racing valve springs) to control modulus, wire/mean diameter, coil count, and relaxation characteristics. The result: a recoil spring that keeps consistent force through thousands of cycles. Upgrade your Glock with the best parts and accessories from NDZ Performance.

Features:

• Consistent feeding & ejection: Optimized spring force for compact slides where proper slide velocity matters.
• Longevity: Chrome-silicon alloy delivers far greater fatigue life and dimensional stability than standard music-wire springs.
• Race-grade manufacturing: Heat-treated, shot-peened, and stress-relieved after winding for predictable compression & cycle life.
• Performance: Holds force and geometry over many cycles, less spring relaxation than music-wire replacements.
