What Gen Is a Glock 43?

Many shooters ask “what gen is a Glock 43?” or “what gen is glock 43?” The answer is simple:

✔ The Glock 43 is considered a Gen 4-series design, though Glock does not label it officially as “Gen 4.”
✔ It is not a Glock 43 Gen 5; that designation does not exist for this model.

Understanding this helps ensure slide compatibility when purchasing upgrades or replacement parts.

Factory-Style Glock 43 Slide Features

A standard factory slide is made from high-strength steel and treated with Glock’s corrosion-resistant finish. It fits the slim 3.39-inch barrel and uses a single recoil spring assembly.

Key features include:

• Front and rear Glock dovetail sight cuts

• Lightweight, slim profile

• Smooth cycling and reliable performance

• Compatibility with factory internal components

Shooters wanting a direct OEM replacement typically choose a Glock 43 slide complete option, which includes all internal parts installed for plug-and-play convenience.

Glock 43 MOS Slide Options

For concealed carriers wanting a red dot optic, the Glock 43 MOS slide is one of the most popular upgrades. Because the original G43 does not come optics-ready, aftermarket MOS designs provide:

• RMSc-cut or RMRcc-cut mounting

• Taller sights if co-witnessing is desired

• Window cuts to reduce weight

• Enhanced serrations for better grip

Many shooters combine these slides with micro-red dots for faster acquisition and improved accuracy.

Custom Glock 43 Slide Upgrades

If you want personalization, a Glock 43 custom slide offers the most flexibility. Popular custom features include:

• Enhanced side and top serrations

• Cerakote color finishes

• Skeletonized windows

• Diamond-pattern cuts

• Porting for compensated barrels

These upgrades not only improve the appearance but also enhance slide manipulation and weight balance.

Glock 43 Slide Release & Extended Slide Release

A smooth reload depends on efficient slide controls. Many owners upgrade to a Glock 43 slide release or a Glock 43 extended slide release to improve ergonomics.

Benefits include:

• Faster reloads

• Easier thumb engagement

• Better control for smaller hands

These parts pair perfectly with both OEM slides and Glock 43 complete slide builds.
