Heckler & Koch VP-40 & SFP-40 *B.O.S.S

DPM Mechanical Recoil Rεduction System for H&K VP-40 & SFP-40

This system works due to the multi spring intricate rod (3 springs) and controls the functionality of the gun. The third spring, which is contained within the rod, controls the movement of the slide so it never rams on the frame. Also, 2 separate external springs are included with the system. The springs are different in length with the longest being heaviest when the slide is on the battery, so the shooter can fine-tune the weapon for his/her personal standards.

Overall Advantages

• Faster follow up shots
• Improved firing speed
• Slide and frame protection
• Elimination of jams
