Mounting a Red Dot Sight on a Handgun

You will learn how easy it is to install the best red dot sight this year on a pistol in this tutorial. We will discuss all the steps, instruments, and accessories required to properly install a Micro Red Dot Sight (MRDS) on a pistol that is ready for optics.

There are many reasons why you would want to install your handgun with a red dot reflex type optic. The main benefit is that it removes the need for the front sight post to be matched with the rear sight aperture.

Eliminating the conventional method of sight alignment associated with iron sights will dramatically improve the speed and precision of target acquisition.

To complete the Red Dot Sight installation, here are the things you will need:

-Ready Optic Pistol

-Red dot Sight.

-Compatible red dot sight mounting plate

-Mounting kit for Red Dot Sight Manufacturer (Some sights may need this)

-Driver with torque

-Hex bit/wrench or Torx

-Sealant Thread

-Ensure that your pistol is safe and clean.

Steps to Mounting a Red Dot Sight on a Handgun:

Step1: Remove the Factory Plate:

To get started first, remove your pistol slide’s factory plate. This will enable you to remove hex or Torx-style screws.

Remove either from the top of the slide or from somewhere under the slide, depending on your handgun model.

You’ll have to disassemble the weapon and detach the slide from the handgun frame if the factory plate screws are underneath the slide.

Step2: Pick the Mounting Plate Proper

You will need the appropriate mounting plate that fits the footprint of your red dot sight and corresponds to your weapon manufacturer and model once the factory plate has been removed. The manufacturer of pistols and the other third-party vendors have these plates available all the time.

Step3: Fasten the Weapon Mounting Plate

Place your acceptable mount in the slide slot of the factory milled pistol. Put a small amount of thread sealant on each of the plate mounting screws, such as blue Loctite.

Make sure to use a thread sealant that will allow the screws to be easily removed in the future. Screw the mounting screws via the mounting plate onto the pistol slide using a torque driver.

Push each screw until both of them are snug, then finish with 12-15 inch-pounds of torque for each screw. For continuity, switch between torquing each screw and repeating the other twice.

We recommend 12-15 inch-pounds, but be sure to verify the requirements of your sight and gun maker.

Step4: Replace the battery of Red Dot Sight

Now since the mounting plate is safely in place on the pistol slide, it is time for your red dot sight to be prepared. Most of the red dot sights have a battery just below the sight, such as the Holosun 507C.

For this reason, we recommend that you put a new battery in the red dot sight and test its function before it is installed. It’s a good idea to insert a new battery into your optics, even though your battery is on the side or top now.

Step5: The Special Criteria

Depending on your red dot vision, this next move will or may not be needed.

We suggest that you refer to the owner’s manual and consult with the manufacturer to see if any special mounting specifications, such as an additional waterproofing plate required for the Trijicon RMR, are required for your specific optical model.

Step6: Mount the Sight of the Red Dot

Alright, now you can put the view from the prior iterations on the mounting plate that you have secured. You may want to add some thread sealant like blue Loctite or something similar to each of the mounting screws once again.

Tighten each screw down until snug, then twist each screw alternately until stable. A 12-15 inch-pound torque is recommended. We’re suggesting a 12-15 inch-pound torque. Be sure to review the torque recommendations of your manufacturers.


Now you are set to roll on your favorite weapon with a newly installed optic. We recommend a journey to the range for some time on goal if you have never used a red dot sight before.

You will be on the way to quicker target acquisition and improved accuracy with only a few hours of practice.

 However, you can check the mounting screws during daily maintenance work from time to time.
