Previous reviews are about the spring with +P ammo. How about lighter loads? I wish to use downloaded ammo and need a lighter spring to stop stovepipe Manufacturer Answer

Works Great. by HellKnightHicks, Verified Owner, August 21, 2022
Bough this because another reviewer said he runs 45 Super with his suppressor. Its crazy how it tames the gun down running regular loads or even +P or 45 Super. I've looked into the 460 Rowland conversion. I really like the round. But I don't like...

I installed this in my FNX45 tactical with a suppressor and Deltapoint pro. I load .45 super for this pistol and this guiderod spring assembly is the ticket to 50 yard hits on feral pigs with this combination. Well worth the price of admission.

Smooth operator by Rick, January 18, 2020
This helps to slow slide velocity when running fast stepping +P ammo and running a suppressor. The recoil impulse is reduced to a push instead of the usual snap. This product is easy to install and does not alter the original pistol.

Undecided for now by Chknlivers, Verified Owner, June 23, 2025
Seemed to slightly affect accuracy with heavy spring. May have something to do with lock time. I.E. my fault. Barely noticeable difference in recoil, but i bought my fnx used, so i dont know if it's all original or not. Lighter spring seems about the...

Product Info for DPM FN Herstal FNP 4.5in/Tactical 5.3in Barrel .45 ACP Mechanical Recoil Reduction System

The Mechanical Recoil Rod Reducer System is a direct replacement for the stock recoil rod that does not change the configuration of the gun. Able to fit a variety of calibers and models, this recoil rod reducer system from DPM features three different external springs that accompany it. The third spring contained within the intricate rod controls the movement of the slide that never rams against the frame. Also two separate external springs accompany the DPM Mechanical Recoil Rod Reducer 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. This DPM Recoil Rod Reducer System is made from high quality metals and will last for thousands of rounds. An amazing feature of this recoil rod reducer system is that it is designed to fit a variety of guns. Included with the DPM Recoil Rod Reducer System for FN Herstal are two different springs. The longer spring is accompanied by a thin piece of plastic that ensures the springs do not slip within the recoil rod.image
