DPM MS-SI/21 Sig Sauer P220 Swiss Army Special Edition 9mm

Enhanced Recoil System for Sig Sauer P220 Swiss Army Edition

Recoil Road Base: 10.5mm

This system operates using a multi-spring intricate rod (3 springs) to control the gun's functionality. The third spring, contained within the rod, manages the slide's movement, preventing it from ramming the frame. The system also includes two separate external springs, allowing the shooter to fine-tune the weapon to personal standards. The longer spring, with more coils, is stronger and has a heavier pound rating than the shorter spring.

The system includes two different spring plugs. The spring plug with the marked groove offers a heavier buffer effect, while the spring plug with a flat surface provides a lighter buffer effect (slide full open position).

Overall Advantages:

• Faster follow-up shots
• Improved firing speed
• Slide and frame protection
• Elimination of jams
• Significant recoil reduction
• Better double-tap concentration
• Better control and greater accuracy

System of Multiple Springs:

Three or more springs of different sizes are used for specific compression, housed in a metal tube. The system's mission is to control the backward motion of the slide at the moment of the bullet's firing. The initial pressure exhibited by the system is almost the same as the standard factory springs. However, at the final phase of the system's coiling, the pressure difference exerted on the slide is 80% - 100% more. Consequently, the slide never rams against the frame, and jams are eliminated.

Materials:

All metal elements are made of stainless steel W.-Nr./Grade 1.4301 (AISI 304) in a factory compliant with ISO9000. All springs are made of steel or high carbon steel with a cadmium (Cd) finish. The cadmium finish, which adds considerable cost to the manufacturing process, makes the spring impervious to the elements, including salt water.
