Minimal difference - DPM SIG P320 Full Size Barrel Mechanical Recoil Reduction System

Tested today against standard recoil spring and steel guide rod that takes 1911 springs. Minimal difference between the stock recoil spring, even less compared to a 12 lb. 1911 spring. Maybe 10% less recoil and better follow up compared to stock, 5% better compared to 12 or 13 lb 1911 recoil spring. For the price I don't think it's worth the very modest gain. I'd recommend a steel guide rod w 12 or 13lb 1911 spring at a 3rd the price.
