RECOIL SPRING KMR 4,5″ SOFT (11)

KMR Recoil Spring – 4.5″ Soft (11 lbs)

The KMR 11 lb “Soft” Recoil Spring is a precision-tuned performance component designed for shooters who want to fine-tune the cycling dynamics of their 4.5-inch KMR pistols. By reducing the spring tension, this component allows for a smoother recoil impulse and faster slide transitions.

Performance Tuning for Competition

Standard factory springs are often “over-sprung” to ensure reliability with a wide variety of high-pressure ammunition. For the competitive shooter using specific loads, the KMR 11 lb spring provides a significant advantage. It allows the slide to travel more freely, reducing the harshness of the recoil and, more importantly, preventing the muzzle from “dipping” downward as the slide slams back into battery.

Technical Specifications:

• 11 lb Tension Rating: Classified as “Soft,” this weight is ideal for light-recoil competition loads (Minor Power Factor).
• High-Grade Spring Steel: Manufactured from premium music wire/alloy steel to maintain consistent tension over thousands of cycles without taking a “set.”
• Optimized for 4.5″ Slides: The length and coil count are specifically engineered for the internal geometry of KMR 4.5″ models (such as the L-02 and W-02 series).
• Consistent Force Curve: Designed to provide a linear increase in resistance, ensuring smooth unlocking and reliable feeding.

Key Benefits:

• Flatter Shooting: Minimizes muzzle movement, allowing for faster follow-up shots and easier sight tracking.
• Reduced Fatigue: The softer recoil impulse makes high-volume shooting sessions more comfortable and less taxing on the hands and wrists.
• Custom Cycle Speed: Perfect for shooters looking to achieve a “snappier” slide feel without the heavy impact of a standard spring.
• Reliable Ejection: Helps ensure full slide travel and positive ejection when using lower-velocity ammunition.

Note: When using a lighter recoil spring, it is recommended to monitor your recoil buffer and ensure your ammunition provides enough energy to cycle the action reliably.
