S&W M&P45 Thumb Safety 4” Barrel Recoil Spring Assembly Instructions

The DPM S&W M&P45 Thumb Safety 4” Barrel Recoil Reduction Spring Rod 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.

The DPM S&W M&P45 Thumb Safety 4” 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.

Advantages:

• Faster follow up shots
• Improved firing speed
• Slide and Frame Protection
• Elimination of jams
• Significant recoil reduction
• Better double-tap concentration
• Better control and greater accuracy
• No gunsmith required
• Lightweight Aprox. 18gr - 20gr

The system includes:

1x DPM Recoil Spring Rod
2x External springs.

This recoil springs are a direct replacement for the stock recoil rod and does not change the configuration of the pistol.

The external springs are different in length with the longer offering heavier slide travel and locking than the shorter spring.

*Dimensions of the spring are the same as the original.
