Top 5 Accessories for the Glock 48 MOS Every Owner Should Consider

The Glock 48 MOS is a slim, reliable handgun that's a favorite for concealed carry and self-defense. Lots of owners like to tweak it for better performance, comfort, or just to make it their own. The right accessories can really make the Glock 48 MOS easier to shoot, carry, and set up for your style.

Pick upgrades that fit your daily routine, and you'll probably notice a real difference in how the gun handles. Sometimes just a couple of key accessories can change the whole shooting experience.

1) DPP Titanium Adapter Plate for Glock 48 MOS

The DPP Titanium Adapter Plate fits the Glock 48 MOS and lets you mount popular red dot sights like the Holosun 407K or 507K—no need to mess with the slide. The plate stays thin, so your optic sits nice and low.

Since it's made from titanium, you don't have to worry about rust, and it holds up well through regular use and recoil. Shooters often pick this plate for its strength and lightweight feel.

It's built for the factory MOS cut, so installation is pretty simple, especially with the included screws. Price-wise, it's usually a better deal than some other brands out there.

People like the secure fit and durability of the DPP Titanium plate. Even though it's slim, it doesn't budge and keeps the optic steady. You can check out more details on the official DPP Titanium Adapter Plate product page.

2) Hellcat OSP Holosun 407k/507k Optic

Holosun 407k and 507k red dots are a go-to upgrade for compact pistols, including the Glock 48 MOS. They make target acquisition faster and boost visibility, so lining up your shot feels easier.

You'll need an adapter plate to mount one, since the optic’s footprint doesn’t match the Glock’s factory MOS cut. Plates designed for the RMSc optic cut—like the DPP Titanium Adapter Plate—let you install the red dot securely, no slide modifications required.

These plates are CNC machined for a precise fit and usually include the hardware you need. The recoil posts add extra support, making them a solid pick for regular carry.

Adding a Holosun red dot to your Glock 48 MOS can really help with aiming, especially in low light or under pressure. It’s a noticeable upgrade for both new shooters and old hands.

3) Recover Tactical GR43 Rail Adapter

The Recover Tactical GR43 Rail Adapter gives Glock 48 models (without a rail) a Picatinny rail, so you can attach lights or lasers. It’s a handy way to add function without fuss.

Made from tough polymer, it’s lightweight and doesn’t add much bulk. You won’t have to permanently alter your gun, either—just attach it and go.

The adapter fits snugly and doesn’t shift around during normal use. If your Glock 48 MOS already has a factory rail, Recover Tactical recommends the OR43 instead. The GR43 is just for versions without a built-in rail.

You can grab the Recover Tactical GR43 Rail Adapter from places like Recover Tactical. It’s a smart pick if you want more accessory options but don’t want to modify your Glock.

4) Trijicon RMR Type 2 Red Dot Sight

The Trijicon RMR Type 2 Red Dot Sight is a top choice for Glock 48 MOS owners who want fast and accurate aiming. Its compact, rugged build works well for concealed carry.

The optic uses a clear LED dot, so you can get on target quickly. The 3.25 MOA dot size is pretty versatile for both close and mid-range shots. Battery life is impressive—up to four years on medium settings, so you don’t have to swap batteries often.

Built from tough aluminum, the RMR Type 2 shrugs off bumps and rough handling. You can adjust the brightness to fit whatever lighting you’re dealing with.

It mounts easily on the Glock 48 MOS, since it uses a popular footprint. The RMR Type 2 is known for holding zero, even after a lot of use. If you want to learn more, check out the Trijicon RMR Type 2.

5) Streamlight TLR-7A Weapon Light

The Streamlight TLR-7A is a compact weapon light that fits the Glock 48 MOS nicely. It throws out 500 lumens, which makes a big difference for target ID in low light. The small size keeps your pistol balanced and easy to carry.

Its low-profile switches work for both lefties and righties, and the safe off feature helps prevent accidental activation when you’re carrying or storing the gun.

Thanks to the rail clamp system, installation is quick—no tools, no extra parts. You can pop it on or off in seconds.

Streamlight built the TLR-7A to handle tough use. It’s made from durable materials and performs reliably. If you’re after a dependable light for your Glock 48 MOS, this one’s a strong option.

Streamlight has a full fit guide for weapon light compatibility. More info on this model is on the TLR-7A product page.

Choosing the Right Accessories

Picking accessories for the Glock 48 MOS isn’t just about looks. The right gear can boost comfort, performance, and safety, making sure your pistol works the way you want.

Compatibility Considerations

Not every accessory fits every Glock 48 MOS. Always check if a part supports the MOS (Modular Optic System) cutout, especially for optics. Some lights, lasers, or holsters only fit wider Glocks, or they might block the MOS plate.

Look for accessory makers who list the Glock 48 MOS specifically. For instance, some red dot sights are designed specifically for its unique slide footprint.

Magazines are another common upgrade, but not all of them fit the slim 48 frame. Ill-fitting mags can cause misfeeds or failures. Grips and backplates also come in different sizes, and mismatched parts might lead to discomfort or malfunctions.

Quality and Durability Factors

Go for accessories built from tough materials if you want them to last. For sights and optics, steel or aluminum beats plastic every time. Holsters made from thick polymer, leather, or kydex tend to hold up better and provide more retention.

Triggers and extended controls should fit snugly and move smoothly. Loose or rough edges can snag or break, which is just annoying (and unsafe).

If you’re shopping for aftermarket parts and upgrades, check reviews and ratings before buying. Trusted brands usually offer warranties or return policies, which is a nice backup. Good accessories last longer and feel safer, whether you’re carrying every day or just hitting the range.

Enhancing Performance and Safety

Proper installation and maintenance of your Glock 48 MOS accessories help you get consistent results and avoid headaches at the range. Paying attention to the details keeps your upgrades working longer.

Installation Tips

When installing Glock 48 MOS accessories, take your time and use the right tools. Always unload your firearm before starting—sounds obvious, but it’s worth repeating. A padded bench mat helps avoid scratches. Most sights, triggers, and slides include guides, but double-check the manufacturer’s instructions for safety’s sake.

You’ll probably need a sight pusher or a small punch and hammer for sights. Don’t overtighten screws—stripped threads are a pain. For optics, use a torque driver and a dab of thread locker to keep things from coming loose.

Trigger kits sometimes need gentle fitting. If you’re not sure, it’s smart to ask a gunsmith. Always test for function and clearances after installation. A simple function check—like dry-firing with snap caps—can catch issues before you get to the range. For more details, check this guide to Glock 48 upgrades and tips.

Maintenance Best Practices

Regular care keeps your accessories working and extends their life. Wipe down metal parts with a clean, soft cloth after shooting to prevent rust. Pay extra attention to upgraded triggers and optics mounts. A nylon brush helps get dust or grit out of tight spots, especially around the slide and barrel.

Just a drop of gun oil on moving joints is enough—too much oil attracts dirt and makes cleaning harder. After range time, remove any optics and store them in cases. Check mounting screws for tightness, since shooting can shake them loose.

Inspect fiber optic or tritium night sights for chips or fading. If something shows heavy wear or acts up, fix or replace it before your next session. For more cleaning tips and care advice, see these Glock 48 accessories and upgrades.
