DPM MS-SI/1 SIG SAUER P 220 NITRON FULL SIZE Cano 4.4" .45ACP

This system works due to the multi spring intricate rod (three springs) and controls the functionality of the gun. The third spring which is contained within the rod controls the movement of the slide so it never rams on the frame. Also accompanying this system are two separate springs so the owner can fine-tune the weapon for his/her personal standards.

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 for specific compression, housed in a metal tube. The mission of the system is the control of the backward motion of the slide at the moment of the bullet's firing. The initial pressure, that the total of the system exhibits, is almost the same with the standards of the factorial springs. But at the final phase of the system's coiling the difference of pressure that is exerted on the slide is in the order of 80% - 100% more. Consequently, the slide never rams against the frame and jams are eliminated.

Materials
All metal elements: stainless steel W.-Nr./Grade 1.4301 (AISI 304) - made in a factory compliant to 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).
