About the Staccato CS 3.5″ Barrel by DPM Systems:
The Staccato CS 3.5″ Barrel by DPM Systems replaces the original factory guide rod/spring system and produces an advanced recoil reduction by absorbing the shock gradually and slowing the slide down before its impact with the frame of the pistol. Because the system is an interior modification of your pistol it will not change the external dimensions of the handgun, therefore there is no for a new holster, sights or any other accessory you own.
New DPM Recoil Reduction kit for Staccato CS 3.5″ Barrel with 4 different adjustable settings.
Will Fit: Staccato CS 3.5″ Barrel
The DPM Staccato CS 3.5″ Barrel recoil spring system works due to its multi spring rod design (three springs) by producing an advanced recoil reduction technique by gradually slowing the slide down before impacting the frame of the pistol using Spring No. 1 (see fig. below) and Spring No. 2. The third spring (Spring No. 3) which is contained within the rod itself controls the movement of the slide so it never rams on the frame.


DPM Mechanical Recoil Reduction System for Staccato CS 3.5″ Barrel
The kit along with the mechanism, includes 1 Bushing and 4 different in length and tension external springs.
The bushing must always be installed when the DPM Recoil Rod and springs are used.
The external springs are different in length and tension, the long spring is heavy and the short is lighter so the shooter can fine tune the pistol on the opening and locking positions (slide on the battery) according to his/hers personal standards.
The active springs are offering additional buffer to the mechanism, this is a new innovation of DPM Systems.
The 2 black coated springs have wire diameter 1.05mm and are softer than the 2 (1x silver) and (1x gold) coated springs with wire diameter 1.15mm.
