How To Manipulate Your Slide Stop

If you ask a person experienced in a skill how they do
something, they may have to pause and think about how to answer. Even after putting some thought into breaking
down an action in one’s own head, trying to move that information out and into
an explanation can be difficult. This process
is what makes effective educators and instructors so valuable. They can communicate an idea, concept, or
skill to where the receiver can understand it.

Over the years of firearm handling, some things just become
second nature. Manipulating thumb
safeties, magazine releases, and slide stops are just things we do. As an instructor, breaking those actions down
into easy to understand bites can sometimes be challenging. A simple explanation of “you just do this”
and demonstrate an action does not always yield the intended results.

I talked with a fellow instructor, friend, and colleague
recently, and we were jibber-jabbering about everything under the sun. One of the things that my fellow instructor
brought up was how difficult teaching how to engage the slide stop on a
semi-automatic pistol could be.

For those of you that don’t know what the “slide stop” is on
a semi-automatic pistol, a quick rundown is it is a lever or switch, that when
engaged, will allow the firearm to be locked open. The below illustration points out the slide
stop on a 1911 pistol.

The slide stop is usually easily engaged or disengaged via
the shooting hand’s thumb on a right-handed shooter. Of course, consult the manual for any
particular firearm you are using to precisely understand how the slide stop
work. I would say that every
semi-automatic pistol will have a slide stop or bolt release that can be
manipulated externally of some sort, but that is not true. There are models out there that lack such a
component, though few and far between.

Much like my friend, I’ve found myself more than once struggling
to explain exactly how to manipulate the slide stop while retracting the slide
on a pistol, when a student does not just naturally take to the operation,
getting past this part in the learning process the learning stalls.

First, let’s go through the process in the context of
checking if a firearm is loaded or not and clearing it. Keep your finger off the trigger, and
remember to keep the gun pointed in a safe direction. If an external mechanical safety can be
engaged with the pistol in that state, engage it. Remove the magazine from the firearm. Pull back the slide with the non-shooting
hand and when fully retracted, engage the slide stop with the thumb of the
firing hand.

Based on my experience, here are some things to consider and
keep in mind when learning how to engage the slide stop if you are experiencing

  • Feel comfortable and be proficient in pulling
    back and exercising the slide of the firearm.
    In a safe area, with an unloaded gun and no ammunition in the area,
    keeping your finger off the trigger, practice pulling the slide several times
    to get a feel for it. Fully pull the
    slide back and know where it stops.
  • Examine the firearm. Know exactly where the slide stop is on the
    pistol and consult the manual. Read the manufacturer’s
    instructions on exactly how they break down this operation. Know which way and where you need to push the
    slide stop to engage it. Generally
    speaking, you’ll be pushing upward on the slide stop to engage it.
  • If you have a chance to, have someone
    demonstrate the action slowly, paying particular attention to how they engage
    the slide stop.
  • Just like every firearm model is different,
    every person is different. In the
    illustration above showing the unloading process, the user has very large
    hands. When he manipulates pistols, he
    can easily reach all the controls on a full-sized firearm without issue. While holding the gun (unloaded, pointed in a
    safe direction, and finger off the trigger), examine where exactly your thumb
    lines up with the slide stop. Before
    even trying to engage the slide stop, see where your thumb makes contact with
    it. Does your thumb reach? If your thumb does not reach, you may have to
    adjust your grip to make this happen.

The list above to think about and review came only after I
had two students in a row that were having extreme difficulty engaging the
slide stop. I told them how to do
it. I showed them how to do it. But I did not break down each and every step
in the process while the show and tell was going on because it was second nature
to me. I then realized I do have to
adjust my grip to manipulate the slide stop on certain firearms I use. I also realized that the students could get
so wrapped up in the multiple steps involved that the small details get
lost. While going over this operation as
an instructor, it is easy to lose sight of what a student might be missing
because new gun users may be sweeping the muzzle unsafely. At the same time,
they try to execute this action, and that is where the instructor’s attention
would be drawn.

Like learning any kind of skill, it is vital to study the
operation and go in with a knowledge of how the device actually functions and
operates. Practice the steps of the
process independently before pulling it all together. See exactly how your hand interacts with the
firearm and know how you specifically need to engage the slide stop. Yes, this is easy and second nature to some
of us, experienced and not experienced in firearm use, but if this does not
come easy the first time, it’s not the end of the world. If you think about what you’re doing, keep
your wits about you, and go slow, learning this operation will come.

Stay safe out there and think before you do!
