DPM Systems -1911-2011 5" - Bull Barrel only - Edward Rivera Special Edition  - MS-1911/ A1-5ER

DPM Mechanical Recoil Reduction System for 1911-2011 5" Bull Barrel - 9 Adjustable User Settings.  

• The World's Only Progressive Triple Spring Recoil System is a revolutionary, patented innovation designed to optimize firearm performance.
• As a direct drop-in replacement for your firearm’s stock recoil rod, it requires no modifications, making it for both professionals and enthusiasts seeking enhanced control and reliability.
• This advanced system utilizes a proprietary multi-spring mechanism, featuring three nested springs of varying tension, all compactly housed within a durable precision-machined metal guide rod.
• The progressive spring architecture ensures that resistance increases as the slide moves rearward, offering a controlled deceleration that reduces wear and improves overall function.
• At the core of the system lies the third internal spring, which uniquely engages during the final phase of slide travel.
• This final-stage damping prevents the violent impact of the slide against the frame, thereby protecting critical internal components from excessive stress and prolonging the service life of the firearm.
• Some systems also include additional external springs and, in some cases, various adapter sleeves, allowing you to adapt the weapon to your personal needs depending on the ammunition used. This is particularly interesting for reloaders.

Advantages: 

• Significantly Reduces Felt Recoil: Enhances shooter comfort and minimizes muzzle rise.
• Faster Target Reacquisition: Allows for quicker follow-up shots and improved accuracy.
• Increased: Minimizes frame battering and reduces the risk of malfunctions, even under high round counts.
• Drop-In Installation: No gunsmithing required—fits seamlessly into compatible firearm models.
• Durability and Longevity: Built from high-quality steel alloys to withstand extreme conditions and thousands of firing cycles.
• Custom-Tuned for Specific Firearms
• This system is especially beneficial in competitive shooting, tactical operations, and high-volume training environments, where firearm longevity, shooter endurance, and consistent performance are paramount.

The Kit includes:

• 1 Multi-spring Rod
• 3 spacers (each a different length)
• 1 spring plug
• 1 red pressure plate tool
• 1 metallic cup screw tool
• 3 different external springs
• The longer spacer gives you a stronger buffer effect, while the shorter spacers reduce that effect for a lighter feel
• The washers only affect how much resistance the slide has when fully open, and the external springs only affect how the slide closes (when it’s in battery).
• The external springs also come in different lengths—the longer spring is stiffer, and the shorter one is softer. This lets you fine-tune how the slide opens and closes to match your personal shooting preferences.
