I'll start with a word of advice, do NOT do a general Google search when looking for this product. Trust me on this, I've included the appropriate link here to save you from seeing things I cannot un-see.

Next up, is the pink elephant in the room, how ‘bout that name, eh? I’m not sure if the name is pure genius from a marketing standpoint, or a little tacky, but either way, you WILL remember it, so I lean toward the genius part. The owner, George Fournet is a proud United States Marine, so to me the salty product name makes perfect sense. OK, now that we have that all cleared up, let’s get to the good stuff!

The Cock Bloc, is a slide rack assist device that allows anyone who has trouble operating the slide on their semi-automatic handgun, for whatever reason, to do so with one hand and minimal effort.

The product is a simple, injection-molded plastic “block” (not an actual “bloc,” which is a group of countries or parties with common purpose) with a base and a protrusion shaped roughly like the muzzle of your semi-auto handgun with recesses for the barrel and recoil spring guide.

When you push the muzzle of a pistol against the protrusion while holding the grip, it pushes the slide back far enough to lock the action open, if the magazine is empty, or to chamber a round. So instead of relying on the strength of two hands and two forearms, the Cock Bloc lets the user put the strength of their entire arm into the operation. The block can also act as a range-bench stand for a pistol with the slide locked open.

The wide base has screw holes, so the block can be affixed to a range bench, wheelchair, or wherever it’s most convenient (while keeping the muzzle pointed in a safe direction) if desired, but it can also work when set on a flat surface, like at tabletop, with no screws necessary.

Both the block itself, as well as the concept, are brilliantly simple, and a revelation for anyone having trouble racking the slide of their semiautomatic. It was designed after certified firearms instructor George Fournet repeatedly watched some of his students struggle to rack their slides during his training classes.

Seeing a need, he developed the Cock Bloc, along with the name. It’s the safest way I’ve seen so far, to manipulate a semi-automatic pistol using only one hand and doesn’t add any protrusions or wings to a pistol’s slide, like some other slide-assist devices do.

Available in 2 models; the Cock Bloc will fit nearly any semi-automatic handgun.

The Alpha is designed for pistols with a large outside diameter recoil spring guide rod. The Bravo is designed for pistols with a smaller outside diameter rod. For my testing, my Honor Defense pistol worked flawlessly with the Bravo bloc, while my Springfield XD worked well in the Alpha bloc.

And 1911 fans, don’t worry if you don’t have a full-length guide rod that protrudes when the slide is pulled back, the Bravo block will work for most 1911s as well.

Now you might be thinking, why would someone need a device to help rack the slide of their gun? There are several reasons:

  • Physical disability

  • Amputees

  • Weak hands

  • Arthritis

  • Long day at the range

  • Temporary injury to an arm or hand

If you don’t fit into one of the above categories, congratulations! But, just because you don’t have a current need for a rack-assist device, you should know that the Cock Bloc makes an excellent pistol display stand.

Whether you’re using it to hold your gun while you clean, stipple your grip, or just while displaying it in a showcase, your pistol will stand securely and safely.

I put my blocs through a variety of tests. On the shooting bench, they come in handy after a long day at the range. Racking your slide for the umpteenth time can start to take a toll on your hands, especially if your gun has a heavy recoil spring.

When I used the product to display my guns, they were held securely in an open and safe position, and they work great for instructors so they can talk about and point out parts of the gun while not handling the firearm.

Just remember: Always keep your block mounted in a position so that when you do rack your gun, your barrel is still pointed in a safe direction. The Cock Bloc is an inexpensive, handy gadget for differently abled shooters that can also be kept in the average shooter's range bag so help reduce physical fatigue during extended range sessions.

Even if you don’t have a physical disability, you may at some point have an injury to one of your upper extremities that could preclude you from racking, or forcing you to use you handgun’s rear sight to rack the pistol one handed, if that’s an option. Having a Cock Bloc on hand will make sure you’re always ready to go and that you can easily and safely ready your EDC firearm for carry each day.

I love that it was designed after seeing a need, by an American Marine. I also love that it’s a 100% American-made product. Right now they only come in black, but so did Fords when they first came off the assembly line. MSRP: $29.95
