This Advanced Unique Adjustable Recoil Reduction System offers 8 adjustable settings to the user, by using the 2 Different Self Lock Spring Plugs, and the 4 different in power external springs.

The system works due to the multi spring intricate recoil rod (3 different energetic springs), controls the functionality of the pistol and replaces the stock recoil rod without requiring any modification.*

The kit includes 4 different in length and strength external springs and 2 self-lock spring plugs, for the 2 gold coated springs their wire diameter is 1.15mm and are lighter during the slide travel than the 2 silver coated springs with wire diameter 1.2mm.
