CYA Supply Co. Recoil Grips

You can install these grips in minutes—no special tools needed. They blend in with the Glock’s look, so nothing feels out of place.

If you want a better grip without messing up your handgun’s feel, these are worth a look. They’re often recommended in lists of popular Glock 43X accessories.

Extended Magazine Base Plate

An extended magazine base plate is a quick upgrade for the Glock 43X MOS. Swap out the factory floor plate, and you get a few nice perks.

Most extended plates let you squeeze in extra rounds, so you reload less and carry more peace of mind. Some also give you a little more to grip, which can make the gun easier to handle.

Many brands use aluminum instead of plastic, so the plates last longer and add a touch of weight. NDZ Performance and GlockStore both make extended aluminum magazine base plates that are tough and look sharp.

The extra weight at the base helps balance the gun, making follow-up shots smoother. You’ll find different finishes and styles to match your setup.

Upgrading with an extended base plate is fast and valuable for many Glock 43X MOS owners.

Compensator for Glock 43X MOS

A compensator can really change how the Glock 43X MOS shoots. Add one, and you’ll notice less muzzle rise and recoil, so your follow-up shots come quicker and stay on target.

You’ve got options made just for the 43X MOS, like the HC43 Compensator. It fits Glock 43, 43X, and 48 models with 1/2 "x 28 threaded barrels.

Most compensators go right onto the threaded barrel—no special skills required. Just make sure to follow the instructions for safe and reliable use.

Keep in mind that a compensator adds some length to the barrel. This may affect your holster fit or how you carry it, so double-check your gear before committing.

If you want a smoother shooting experience, especially when you’re shooting fast or under stress, a compensator is a popular pick.

NDZ Performance Rear Slide Plates

NDZ Performance rear slide plates are a favorite upgrade for the Glock 43X MOS. They’re made from aluminum, so they’re more rigid than the factory plastic and hold up to hard use.

These plates fit the Glock 43X, 43, and 48—all in 9mm. You can swap out the original slide cover plate for one with a custom color or image, adding a personal touch to your Glock.

NDZ machines each plate for a precise fit. There are plenty of customization options to match your style, as well as other upgrades.

Swapping plates is simple and doesn’t require permanent changes—many owners like that these rear plates are made in the USA.

If you’re looking for a reliable part that also looks good, NDZ Performance plates are a solid choice.

Upgraded Metal Sights

Upgrading to metal sights makes a real difference on the Glock 43X MOS. They outlast the plastic factory sights and take daily carry or training in stride.

Night sights with tritium inserts are a popular choice—they make aiming in low light much easier. Some models have bright color outlines for daytime use. Either way, you’ll pick up the front sight faster.

You’ll find several brands making metal sights for the 43X MOS. The Glock OEM Night Sight Set is a good example, offering both front and rear replacements in sturdy metal.

Good sights boost accuracy and give you confidence, whether you’re on the range or relying on your Glock for defense. Usually, you can install them yourself, although sometimes a gunsmith is the best option for perfect alignment.

Compatibility Considerations for Glock 43X MOS Accessories

Every accessory has to fit the Glock 43X MOS’s unique size and features. Picking the right parts saves you headaches and ensures everything works as intended.

Understanding MOS Platform Specifications

The Glock 43X MOS comes with a factory-milled slide for direct mounting of micro red dot sights, like the Trijicon RMRcc or Shield RMS. Not every optic or accessory fits without the use of mounting plates or adapters. The rail is shorter than on larger Glocks, so double-check the size of any light or laser before making a purchase.

If you’re shopping for a red dot, make sure it’s built for the 43X MOS’s slim frame. Holsters also have to fit any added bulk from optics or lights. For sights, only options made for the narrow 43 mm frame will line up correctly.

Here’s a quick look at key MOS specs:

Accessory Installation Tips

Before you install anything, review the product’s manual and compare it with Glock’s instructions. Use torque limiters for optics so you don’t overtighten and strip screws or damage the slide.

If you’re adding a light or laser, make sure the mounting arm fits the single-slot rail snugly. Don’t force it—this rail can bend if you’re rough. When swapping iron sights, a sight pusher tool is better than a hammer for a cleaner installation.

After you’ve installed accessories, rack the slide and check all functions. Make sure nothing blocks the ejection port or rubs on the slide. Dry-fire testing helps ensure smooth cycling. For more tips, check out Glock 43X upgrades and install steps.

Maximizing Glock 43X MOS Performance in 2025

Keeping your Glock 43X MOS in top shape takes some care and smart accessorizing. The right approach means you get more reliability and a better concealed carry experience.

Maintenance Practices for MOS-Compatible Upgrades

Regular cleaning and inspection keep the Glock 43X MOS running smoothly, especially if you frequently swap slides or optics. Gunk builds up around mounting plates and optics, so clean under those parts every time you maintain your gun.

Key maintenance tips:

• Clean the optic cut and mounting surfaces

• Check screws for tightness with a torque wrench

• Inspect sights and electronic parts for damage

• Use the right lubricants to keep small parts moving

It’s smart to keep backup iron sights alongside a red dot, just in case the optic fails. For more information, check out performance-enhancing upgrades for the Glock 43X. Regular checks and careful assembly go a long way.

Impact of Modern Accessories on Concealed Carry

Modern add-ons—like slim weapon lights, optic-ready holsters, and extended mags—change how the Glock 43X MOS fits into your daily carry. Compact red dots help you find your target fast, but they can make the gun a bit bulkier.

Most concealed carriers go for minimalist lights and slim magwells. The right holster should protect your optics or lights without adding too much bulk.

It’s worth testing new accessories at the range to make sure they don’t snag or shift as you move. For practical upgrades and fit ideas, check out these top Glock 43X MOS accessories and see what works for you.
