DPM for Staccato P 4.4″ Bull Barrel

About the Staccato P 4.4″ Bull Barrel by DPM Systems:

The Staccato P 4.4″ Bull Barrel – 6 Adustable user settings 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.

This Mechanical Recoil Reduction System is a direct replacement for the stock recoil rod and does not change the configuration of the pistol. As always, DPM products are designed and developed with user’s safety as a priority. Exceptional manufacturing and engineering using high-end materials.

*B.O.S.S: Black Oxide Stainless Steel  its an innovative coating technology applied usualy on the visible parts of the recoil system.

Staccato P 4.4″ Bull Barrel

The DPM Staccato P 4.4″ Bull 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.

The spring plug must always be installed when the DPM Recoil Rod and springs are used.

This DPM Mechanical system works due to the multi-spring intricate rod (three springs) and controls the functionality of the pistol. The third spring which is contained within the rod controls the movement of the slide so it never rams on the frame.

The system includes 1 Bushing, 1 Washer and 3 different in length and strength external springs.

The Bushing must always be installed when the DPM Recoil Rod and springs are used.

The external springs are different in length, the long spring is heavy and the short is light 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 metallic washer is not mandatory to be used, it is designed to offer additional optional recoil reduction choices.
