Trapezoid Grip Slide Lock for the Glock

Brass Stacker Trapezoid Grip Slide Lock

Brass Stacker is selling something called a Trapezoid Grip that claims to make field stripping Glock pistols easier.  The Trapezoid Grip replaces the factory slide lock and provides more surface area for fingers to engage, yet does not extend beyond the frame profile of the handgun.  The grips are made of milled steel and retail for $12.

    Cause, you know, its SOOO hard to field strip a Glock currently.. I mean it takes, like, EIGHT seconds at least, AND the hand strength of a 9 year old.

    • MrSatyre

      So anything that makes something easier is automatically bad, huh?

      • Vhyrus

        Anything that solves a problem which doesn’t exist is useless. But, hey, its your twelve bucks. If you want to void your Glock’s warranty, who am I to judge?

        • 2wheels

          While I wouldn’t buy one of these if I owned a Glock, the last thing I’d be worried about is it voiding my warranty…

        • The Glock is so simple I wouldn’t be concerned about my warranty.

          I don’t know about others but I’ve only sent one gun in for warranty repair. It was worth it to just fix the few others and not be without the gun for a month or more.

        • MrSatyre

          I forgot, the universe revolves around you. My apologies.

    • Patrick Henry,The2nd

      I find it quiet annoying to field strip my Glock. Its damn annoying to pull those stupid things down at the same time and move the slide right.

      So yeah, this is a great idea.

  • Jesse Welling

    If you need this to field strip your Glock you probably clean it more than you shoot it.

    • DaveP.

      Or you’re a woman or a disabled man and don’t have a lot of 2-finger grip strength. Or you sweat a lot and it makes your grip slippery. Or you spend a lot of time in the outdoors and might have to clean your gun when it’s wet/muddy or when you’ve got gloves on. Or you’re an older type with arthritis.
      Or you just want to make the job a little easier, even if you don’t do it frequently.

  • RickH

    Good idea! Doesn’t interfere with anything and is unobtrusive. I’m surprised Glock hasn’t modified this in all these years. I’ve never had a problem with the stock unit, but what’s wrong with making it easier?

    • gunslinger

      why not just have glock factory install?

      • Aaron E

        This is not a Glock part. Glock will not install any non-Glock parts, and yes adding or removing Glock parts may void a warranty (something that most manufacturers have in writing to protect themselves from liability).

        • gunslinger

          I meant why doesnt glock have a part like this? If it is such a need, why isnt it standard?

  • Christina Leah

    Not sure why anyone has anything negative to say about this. No one is forcing you to use or buy this part. If you like the stock part, you lose nothing.

  • William Highfield

    One thing about this part is that it WILL scratch up your IWB holster. Personally, I don’t care because, well, it’s a IWB holster and nobody sees it, but I thought I’d put it out there. And yeah, I got it because it does make it significantly faster and easier to field strip my Glock, and if I’m trying to do it in 100 degree Florida sun, I’m usually sweating my ass off, LOL.

  • Ken

    Nothing new here. I’ve got several G’s with this same type of device from another (don’t recall who) manufacturer for years

  • HKGuns

    Is there even a single part on a gLocK that is good to go from the factory? I certainly wonder, with everyone finding better ways to do things with nearly every part of the factory offering.
