Tunable! Includes 3 Strengths of BHSS-Recoil Buffering Springs

And users’ choice of Buffering Spring does NOT require a change of recoil spring strength!

Lifetime Part with replaceable internal springs

Note: ALL “Factory” (OEM) Hi-Power Recoil Spring Guide Rods are a limited life part

All contain a non-replaceable / compressed spring that weakens over time

Universal Compatibility w/ ALL Full-Size Hi-Power Pistols from All Manufacturers:

FN/Browning (Belgium), FM (Argentina), Kareen (Israel), FEG (Hungary), Arcus (Bulgaria), Tisas/Regent BR9 (Turkey), and Others

Hard Part Components Manufactured by EFK Fire Dragon, Inc. in U.S.A.

Spring Components Manufactured by BHPerformance LLC in Bulgaria

Final Component Assembly, Quality Control & Packaging by BHSpringSolutions LLC in USA

When firing a semi-automatic pistol, the slide recoils rearward at great speed, and then comes to an immediate stop (collision) against the frame at full recoil. This force and impact to the frame is constantly weakening the slide and vibrating the internal parts, potentially compromising or wearing parts prematurely, and and excessive recoil results in turning movements in the shooters wrist. This sudden “collision” causes a violent muzzle jump which temporarily pulls the pistol off target and upwards, causing a need for dual-action buffers.

The BHSpringSolutions/EFK Fire Dragon Dual-Stage Buffering Recoil Spring Guide rod offers these advantages:

Impact: The reduction of slide velocity just before impact with the frame preserves the structural integrity of the firearm - and your rather significant investment!

Muzzle Control: By changing the final backward movement of the slide from a sudden stop to a progressive stop, muzzle jump is greatly decreased by up to 40% giving you more control.

Function: No interference with feeding ammunition or extracting empty shell casings.  The slide pull the empty shell casing into the Ejector prior to the slide reaching full recoil – the Dual-Stage Buffering Recoil Spring Guide Rod’s INFLUENCE Starts after the slide’s rearward velocity has achieved the Extraction Sequence.

Progressive: This is a system designed to reduce the backward velocity of the slide in progressive stages after the gun is shot. The effect of this system is that the recoil is reduced by 40% making your follow up shots much easier to shoot. This is a VERY effective system.

Stability: Better stability for your barrel. Stainless steel guide rod replaces guide rods for superior barrel support and function.

Better Accuracy: Progressively slows down your slide from heavy impact against the frame. Works just like a car shock absorber, reducing the slide impact. Lower impact means less recoil, accurate recovery of the weapon for on-target accuracy is better achieved, shot after shot. Even expert shooters can benefit from lower recoil.

Lower Frame Shock: The slide is one of the heaviest components in a semi-automatic pistol. Upon firing, the slide slams back with great energy against the frame.  The Dual-Stage Buffering Recoil Spring Guide Rod can lower this slide impact dramatically, preventing excessive wear.

Why 3 strengths of Buffering Springs?  Some shooters of “light reloads” and competitive shooters using very light reloads may find the Light Buffering Spring preferable for function and control of already reduced recoil.  Some shooters with weak hands might find slide racking against the Heavy Buffering Spring to be a little much, and may prefer the Medium Buffering Spring.  And a myriad of other possible scenarios can make the user’s choice of strengths in the Buffering Springs, an advantage.

Universal Drop In Fit: Direct replacement for your factory Hi-Power recoil spring guide rod assembly.   No modifications required.

Tag for curiosity, anything which might extend the life of my Browning 9mm Hi-Power has my attention.

Interesting.  I do not find the HiPower to have much recoil as is, but I've shot guns with less felt recoil.  Like an all steal 1911, 9mm.

Would be cool if it works.

not needed at all.

This. It seems to me to be a solution looking for a problem. The BHP is, to me, a mild shooter already.

Has anyone out there actually installed and tried one of these?

Mr. BHP himself (the late Stephen Camp) said he used a shock buff.
