Glock 48 Red Dot Sights & MOS Optics

Shop red dot sights and MOS optics for the Glock 48 at MountsPlus. This collection includes compact pistol optics, optic plates, red dot mounts, RMRcc options, Holosun-style sights, Burris optics, Leupold sights, and low-profile choices for concealed carry and range use.

The Glock 48 is slim, easy to carry, and popular for everyday use. Adding the right optic can give you a clearer aiming point and a more confident sight picture, but fitment matters. Before choosing an optic, make sure it matches your slide, mounting footprint, plate system, and holster setup.

Find the Right Optic for Your Glock 48

Not every setup uses the same mounting system. A Glock 48 MOS, non-MOS slide, dovetail mount, adapter plate, or direct-fit optic can all require a different solution.

Before ordering, confirm whether you have:

• Glock 48
• Glock 48 MOS
• Non-MOS slide
• Optic-ready slide
• RMSc-style footprint setup
• Adapter plate requirement
• Dovetail red dot mount
• Suppressor-height sight setup

A correct match helps the optic sit properly, mount securely, and work with your intended carry setup.

MOS Optics and Direct-Fit Options

The Glock 48 MOS is designed for compact pistol optics, but the footprint still matters. Some sights may mount directly, while others may need an adapter plate.

Direct-fit options are popular because they can keep the setup lower and cleaner. Adapter plates can give you more optic choices, but they may add height. Always check the footprint, plate compatibility, screw length, and slide fit before buying.

RMRcc, Holosun, Burris, Leupold, and Compact Optics

MountsPlus carries compact optic options from trusted brands such as Trijicon, Holosun, Burris, Leupold, Bushnell, and others.

Popular choices include the Trijicon RMRcc, Holosun 407K, Holosun 507K, Holosun EPS Carry, Burris FastFire, Leupold DeltaPoint Micro, and other compact reflex sights. Each model has different features, including reticle size, brightness settings, battery access, window size, mounting height, and footprint.

Red Dot Mounts and Adapter Plates

If your pistol is not MOS, you may need a dovetail mount or adapter system. These mounting options may let you add an optic without slide milling, depending on the product.

If you are using a MOS model, you may still need a plate depending on the optic. Check that the mount or plate is made for your slide and your chosen optic footprint.

Choosing Reticle Size

Reticle size affects how the optic feels when aiming. A smaller dot can be useful for precision at the range. A larger dot may be easier to pick up quickly at closer distance.

For carry use, many shooters prefer a balanced reticle that is easy to see without covering too much of the target.

Carry and Holster Considerations

A compact optic should work with your carry style. Think about optic height, snag points, battery access, durability, and whether your holster has enough clearance.

If you already carry this pistol, confirm that your current holster fits with an optic installed. A standard holster may not clear the sight.

Iron Sight Compatibility

Some shooters pair a pistol optic with backup iron sights. Depending on optic height and plate thickness, factory sights may or may not be visible through the window.

If co-witness is important to you, check whether taller sights are needed for your setup.

How to Choose the Best Setup

Choose a direct-fit optic if you want a low-profile setup with fewer mounting parts.

Choose an adapter plate if your optic uses a different footprint.

Choose a dovetail mount if you have a non-MOS slide and do not want slide milling.

Choose an RMRcc or compact carry optic if you want a durable, low-profile option.

Choose a larger-window sight if easy dot pickup is your main priority.

Choose a low-profile optic if concealment and holster clearance matter most.

Confirm Compatibility Before Ordering

Before buying, check your pistol model, slide type, optic footprint, mounting plate, screw length, holster clearance, and sight height.

Some optics require a specific plate or mount. Others may not fit without modification. If your pistol has aftermarket sights, slide cuts, plates, or custom work, confirm compatibility before ordering.

Frequently Asked Questions

What is the best Glock 48 red dot?

The best option depends on your slide setup, carry style, budget, and preferred reticle size. Popular choices include compact optics from Trijicon, Holosun, Burris, Leupold, and similar brands.

Does the Glock 48 MOS need an optic plate?

Sometimes. Some optics may mount directly, while others require an adapter plate. Always check the optic footprint and product fitment before ordering.

Can I put a red dot on a non-MOS Glock 48?

Yes, depending on the mounting system. A non-MOS slide may need a dovetail mount, adapter system, or slide milling.

What footprint does the Glock 48 MOS use?

Many slimline MOS setups are associated with RMSc-style optic compatibility, but fit can vary by optic and plate. Always confirm the exact footprint before buying.

Will a Trijicon RMRcc fit a Glock 48?

It may fit with the correct mounting solution. Check whether your slide is MOS or non-MOS and whether a plate or adapter is required.

Will a Holosun optic fit a Glock 48?

Some compact Holosun optics may work with the correct slide cut, plate, or adapter. Confirm the specific optic model and footprint before ordering.

What dot size is best for concealed carry?

Many users prefer a dot that is large enough to see quickly but not so large that it blocks the target. The best choice depends on your eyesight and intended use.

Do I need a new holster after adding an optic?

Possibly. A standard holster may not clear a mounted optic. Choose an optic-ready holster if your current holster does not have enough clearance.

Can I still use iron sights with an optic?

Sometimes. Co-witness depends on optic height, plate thickness, and sight height. Taller sights may be needed.

What should I check before buying?

Check your pistol model, MOS or non-MOS slide, optic footprint, plate requirement, screw length, sight height, holster clearance, and installation requirements.
