2. Recoil reduction systems for SIG SAUER pistols P320 AXG LEGION AND NEW P320 M.O.D. offer several performance, control, durability benefits, especially for sport shooters, professionals, and anyone seeking enhanced firearm handling.

The DPM Mechanical Recoil Reduction System is a U.S. patented, precision-engineered upgrade designed to replace the factory recoil spring and guide rod assembly in SIG Sauer P320 series pistols. Installation is simple and requires no permanent modifications to the firearm—just drop in the DPM assembly and you're ready to shoot.

At the heart of the system lies a multi-spring internal mechanism, combined with external springs and interchangeable spring plugs. This advanced configuration offers 8 to 9 user-defined spring plug/spring combinations, allowing shooters to fine-tune recoil dynamics based on ammunition barrel length, compensator setup, and personal shooting

Performance parameters:

• Slide-in-battery spring force: approx. 8.1 lb to 9.4 lb (depending on plug)
• Maximum slide-open resistance: approx. 18 lb to 24 lb

 Key Benefits & Intended Use

Backed by U.S. patents and decades of innovation, DPM Systems offer several performance-enhancing advantages:

• Substantial reduction in felt recoil
• Smoother slide cycling and shorter muzzle dip
• Improved control during rapid fire and double taps
• Faster and more accurate follow-up shots
• Extended service life of frame and internal parts
• Enhanced with reduced risk of stovepipes or malfunctions

 User Feedback & Community Reviews

In practical testing and online communities such as Reddit and SIGTalk, users consistently report significant improvements in recoil control and One user on r/P320 noted:

“Recoil is noticeably reduced, and follow-up shots feel much easier to control—especially under rapid strings of fire. I’ve run about 300 rounds with the 9 lb spring and haven’t experienced a single malfunction.”

Comparisons to other aftermarket kits (e.g., Armory Craft 13 lb) often highlight DPM's superior quality, adjustability, and quiet operation (no spring rattle or squeak). While slightly more expensive (~$80–$110), users consider it a premium-level upgrade with tangible benefits.

 Compatibility Across SIG Sauer P320 Variants

DPM offers model-specific kits to ensure optimal fit and performance across the SIG P320 lineup:

 Recommended Applications

• With compensators or ported slides (e.g., X‑Carry Legion, Spectre Comp): the standard or “soft” DPM version improves slide timing, reduces muzzle flip, and ensures cycling.
• For heavy or +P ammunition (e.g., P320 XTEN 10mm): the heavy-duty kit offers reinforced spring tension for smooth operation under demanding loads.
• Stock pistols: even without modifications, the DPM system enhances shooting comfort, accuracy, and longevity.

 Installation & Tuning Tips

1. Remove the factory recoil rod and spring.
2. Install the DPM recoil rod assembly in the same manner.
3. Choose spring plugs and external springs based on your ammo and setup. Start with the mid-strength configuration.
4. Test-fire in batches of 25–50 rounds to ensure function.
5. Adjust spring strength as needed:

Use a heavier spring if the slide is overtraveling.

Use a lighter spring if the slide fails to return to battery.

 Summary

The DPM Mechanical Recoil Reduction System, protected by multiple U.S. patents, is an advanced, modular upgrade for SIG Sauer P320 pistols. Engineered for precision and durability, it provides shooters with:

• Tailored recoil control
