Why a gun recoils at the moment of the gunshot?

For every action there is a reaction. When a primer is hit and a bullet is discharged the energy of the bullet moving forward causes a rearward reaction of energy. Therefore you get recoil in your weapon.

What is the Magnetomechanical system?

This system is utilizes a magnet incorporated into a plastic base which in cooperation with the mechanic system of multiple springs, control the acceleration and the deceleration of the slide that is caused from the gun's bullet firing. The momentary delay that is caused in the slide, from the presence of the magnet, harnesses the maximization of escape of gases from the barrel's muzzle. The mechanical system of multiple springs absorbs the remaining kinetic energy in the slide. Consequently the slide is moving back more gently transmitting less kinetic energy to the frame and slide, and reduces recoil for the user.

What is the 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.

What materials are used?

1. All metal elements: stainless steel W.-Nr./Grade1.4301(AISI 304)-made in a factory compliant to ISO 9000.

2. All Springs are made of steel of 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).

3. Magnetic Base: hard plastic with glass content of 10%.

Recoil Rod Assembly Instructions

1. Disassemble the gun. 2. Replace the standard spring with the DPM multi springs system (metallic guide) as shown below (fig.1, fig.2, fig.3, fig.4).

3. Ensure that the DPM system is placed in the correct way as shown below (fig.5).

4. Reassemble the gun. 5. Before loading the magazine, rack the slide several times to ensure that the DPM System functions unrestricted.

IMPORTANT NOTES

1. Always use the proposed system of DPM multi springs for every type and model of gun, in the way that it is described on the packaging. The use of the system on another model of gun may cause damage to the system (metallic guide and base) and possibly to the gun as well.

2. Always keep your gun and the system (metallic guide) clean using the necessary greasing.

3. Do not try to disassemble the system (metallic guide and base) because it will be destroyed.

4. Always use the recommended spares, accessories, and springs of DPM.

5. USE IN ORIGINAL STOCK FIREARMS ONLY! DPM Systems Technologies and distributors are not responsible for damage or malfunction if products are used in a modified gun.

Our products do not invalidate the existing guidelines concerning the safe and correct way to use your gun. More specifically, DPM Systems Technologies Ltd is not responsible for any damage or injury that may happen due to the incorrect placing or use of its products.
