    interesting but...

    Greek company DPM Systems Technologies makes a very unique device called Magnetomechanical recoil reduction system. It attaches to the host pistol via the accessory rail and replaces the recoil spring assembly. The new spring except returning the moving parts to their initial position, also has a built-in recoil reduction system. And as the name implies, it is composed of not only mechanical recoil reduction means (springs) but also features a magnet assisting the process. The magnet attracts the slide and pulls it closed tighter.

    According to the company, this system locks the slide with double the power and delays the initial opening of the action. They claim that it helps to prevent gasses from escaping through the breech and makes the slide motion more gentle thus reducing the felt recoil.

    Other features of this system are the glass breaker tip made of tungsten carbide and an accessory rail under it. Also, the forward protruding portion should help to prevent the slide from unlocking and going out of battery when the gun is pushed against something. This device is made of 6061 T6 aluminum (black anodized). It is available in the USA (for Glock pistols) through DPM Systems USA website at MSRP of $55.

    Everything sounds good, except it raises many questions. If the magnet forces the slide to close tighter, won’t it cause short stroking malfunctions with certain loads? Won’t it be much harder to rack the slide with increased lockup strength? And obviously, the disassembly is made much more complicated. Nevertheless, usage of magnets in firearms is something not very often seen. In that sense, it is interesting to see where magnets can be employed in the firearms’ design.

    I think magnets can be used in the opposite manner for the recoil reduction. Imagine a magnet in the portion of the gun where the recoiling parts hit the stationary part (say the very bottom of an AR-15 buffer tube) and another magnet mounted on the moving parts (e.g. on AR-15 buffer). The magnets are situated so that they face each other with the same pole and at the very end of the rearward motion of the moving parts (right before they hit each other), magnets will repel each other and soften or even eliminate the impact of the moving parts. These are just my thoughts with no scientific backing or calculations. It would be great to hear our readers’ opinions on this subject in the comments.

    I can see this being problematic in areas with high iron content sand/dirt. Yeah, I want my firearm being magnetic and attracting grit to gum up the works.

    If there is a problem with recoil, put in different springs, get a heavier firearm, put a stock on it, get a different firearm. I just see this as eventually causing more issues than things it solves.

    Curious device. Has anyone seen an independent evaluation yet?

    Watch the video.

    I imagine the load you are shooting will have to match the setup you run, but once you figure that out...Bob's your Uncle?

    DPM also offers purely mechanical recoil reduction systems for various weapon platforms; they appear to be more sound than the magnetic stuff. I haven't been able to locate a reliable source for testing on the magnetic system. Personally, right out of the gate I don't like it because it adds more crap to your sidearm. The in-line mechanical system would be something I would try out if I were a Glock enthusiast, however.

    My pistol is strictly for shooting. I've got a glass breaker pommel on my Swiss Army knife along with a glass saw, and seatbelt cutter. For several years, now, I've seen these products both praised and cursed on various internet gun forums. Suffice it to say that I prefer to use Wolff Gunsprings and solid steel guide rods inside my Glocks; and I don't see myself running out to buy one of these gizmos anytime soon.

    S'funny that the vid does NOT show busting the car windows muzzle leading. Not a glockie, but if I was, I'd think at least twice --

    Any thing you add to the function of any thing,
    say a muti tool,, the wear factor is added as well to all movable parts, unrelated to the task at hand.
    Multi tools I use regularly, need tightening regularly, even to part I am not using .
    To an LEO the might be a boon to their work and drawing a gun is not out of place .
    HOWEVER,
    Being a civilian ,observing/intervening in an event, the victim is trapped in a burring car ,should I draw a gun to break glass, it may compound problems, both of observers and the victim.
    So what looks like is happening Old Miner Arleigh and Friend. , is not actually what happened .
    And a gun is not a hammer.

    Would affect the timing in a 1911 pistol, so scratch on that. I reload, so I can tailor my loads to reduce recoil if I want that effect,

    I do like OldDude49's idea about opposite poles being in play at the rearward stroke of the slide which could speed up cycle time. Might really be useful in open bolt machine guns, and could probably be set up for adjustment for various rates of fire.

    I was thinking about what effects the new neodymium magnets would have on a bullet traveling down a bore, they are so strong that they have interaction with copper, which might increase a bullet's bore time and up pressure with a slow burn rate powder creating a faster bullet without negative effects from over pressure. Did some research before starting experiments and found that this has been tried and what they got was a magnetic wave emanating from the gun barrel that was strong enough to cause a heart attack in humans nearby. Glad I didn't follow through on my curiosity.

    Curiosity killed the cat and will probably take me out at some point.
