Thumb Over Bore With a Pistol?

So there are tons of methods to shooting a handgun. And lots of debate about what to do with your support hand. Isosceles, Weaver, cup and saucer, grabbing your wrist, thumbs high, thumbs forward etc. The list goes on and on. However this is a first. If you subscribe to the c-clamp/thumb over bore AR style of support hand grip, then I suppose there could be justification for putting your support thumb on top of the slide. But I don’t think putting your thumb on top of the slide is a good idea. A whole new meaning to slide bite.

    What? Why is this a thing?

    • Nicks87

      It’s not. Just some confused old man thats too stubborn to take some classes or ask someone to show him a propper grip.

      • plinkster68

        There is no PROPER grip. The only Proper grip is the one that you are comfortable with and the one that works for you.

        • Nicks87

          I said “A” proper grip. There is more than one and personal preference does factor into it. However the grip that was depicted in the photo was not a proper one and most firearms instructors teach pretty much the same one. Nice try, plinkster but you better stick to plinking.

            Reminds me of how some people tried to bat cow-handed.

  • Steve Truffer

    I see jammed gun and busted thumb.

    • sianmink

      There isn’t enough energy there to bust your thumb. I’ve fired a 9mm glock with my thumb pressed right against the back face of the slide with no ill effects for a close quarters malfunction drill (Except obviously the action doesn’t cycle)
      That said, there’s no good reason for this.

      • patrickiv

        If he’s not squeezing it tight then the slide could get up to speed and the front sight could cut him pretty good.

        • Steve Truffer

          That’s what I was thinking.

      • Mael99

        You lost all credibility at “glock”.

        • Joe

          Wow, sounds like an HK nosebleed there. In case you didn’t know, it is a trained technique with modern pistols (i.e. striker fired) that don’t have needless external hammers. You can use your firing hand thumb to stop the slide from cycling. It is normally used to keep the weapon in battery when shooting with the muzzle pressed against the target because of your proximity to the threat. One round to wound your adversary is better than none

  • david

    Yeah, also works great to put your support hand thumb over your dominant hand right behind the slide.

  • 1leggeddog

    Stupid and almost dangerous.

    You risk impeding the functioning of the firearm itself!

  • JumpIf NotZero

    You found a picture of an old guy not knowing what he’s doing… I’m sure there is a Tumbler for that.

    • DoctorTran37

      Maybe even a Thumbler….

    Nicholas C is the king of bad, useless posts

  • 1911a145acp

    Reminds me of a Police Academy recruit that walked into my shop one day with a Charter Arms Undercover .38 snubbie in an Uncle Mike’s nylon holster, LOADED with the hammer cocked. I say- “Hey partner- your hammers back there- that is not safe” He says- “Oh- I carry mine cocked and locked”. A little knowledge… is a very dangerous thing…..

  • 1911a145acp

    Some body please help Grandpa out here with some gentle instruction….

  • dan citizen

    Posts showing poor gun handling should be a weekly thing….. Said no one, ever.

    • William DeWeese

      Actually, they could be great teaching tools, particularly if the results are posted also.

    Reminds me of my buddy’s insistence to use his middle finger as his trigger finger. (He was a pretty damn fine shot.) He had some excuse about having a hinky index finger, he looked like a dork, but not as much as his foray into an auto loading shotgun! First shot, instant “hinky” index finger for sure! Dork.

    • Cymond

      I once saw a website promoting the ‘super secret special shooting technique’ of shooting with the middle finger, and the index finger was placed along the side of the frame, so that aiming was like “pointing your finger”. The website claimed that 1911 pistols were inherently unsafe, because the index finger could bump the takedown pin/slide stop and cause the gun to stop functioning.

      example of this viewpoint:

      • hkryan

        Good thing to practice in case you lose your index finger like Tom Berenger.

        Just kidding…

  • GunRacer

    See, if there was a pistol that had a stationary forward section, you could actually do this. I imagine it’d manage recoil really well.

    • S O

      “If there was”?

      I think most if not all pistols with an exposed forward barrel (such as Parabellum) have this (or almost static). Their sights may even be high enough to make the thumb unproblematic.

  • damien

    I can imagine a pistol without a slide, or one with a static shroud around the moving slide, that would allow this grip. If the pistol had an underbarrel picatinny rail, the shroud could attach to that.

    • hkryan

      Ruger .22…

  • Laserbait

    That will change as soon as he takes his first shot with a revolver!

    • mechamaster

      Uh-huh.. the hot gas bursting from cylinder gap will burn his hand…

  • mechamaster

    Maybe he has a habit to shoot single-shot pistol and do it unconsciously.

  • bill45colt

    reporter needs some training also…thumb is not over bore, its over chamber,,,over bore–one shot–will remedy that problem, over chamber–who cares if he doesn’t block his sights

  • Anthony

    Some friends and I were joking about this at a new years party. Epic lolz

  • rocketman21

    Fools rush in. where angels fear to tread.

  • Hank Seiter

    Absolutely stupid and no reason to do so. I hold my 1911s and XD .45s in such a way that both thumbs lightly parallel the frame right below the slide. I can make center-of-mass hits out to 120 meters using this basic technique.
    Why is someone always trying to reinvent the wheel by using inferior design theory and sub-standard materials because it’s “never been done before”?

  • Art Nickel

    Not to mention that if you squeeze you are apt to incur a malfunction at perhaps the worst time, like when its a matter of life and death…

  • Pete Sheppard

    Reminds me of the time a let an (apparent) revolver shooter fire my Colt Commander. I presume he shot revolvers because he used a thumb over hand grip…then I saw blood flying–he had a nice set of cuts at the base of his thumb from the slide…

  • Hyok Kim

    Why not just put ass over the slide?
