DPM SIG Sauer P226 – P 220 X-Six (Barrel 6"/152mm) Classic Competition Supermatch PCC - 10 Adjustable User Settings
 
This DPM recoil system has 2 spring plugs and 5 external springs and offers full user adjustability. 
 
Included with the system are 5 separate springs. These external springs are different in length (also in power) so the user can fine tune the pistol on the opening and locking positions (slide on the battery) to serve all possible shooting needs. The longer spring (more coils) is stronger and has a heavier pound rating than the shorter springs.
 
The spring plug with the marked groove is offering a heavier buffer effect and the spring plug with flat surface offers a lighter buffer effect (slide full open position).
 
 **As we lead the evolution of recoil reduction technology, products may change versions (new design with different springs, with or without plugs, washers, etc.) without any prior notice.**
