The Glock 43 remains one of the most popular single-stack concealed carry pistols on the market. Its slim profile, lightweight design, and proven Glock reliability make it a favorite for everyday carry, range practice, and personal defense. While the Glock 43 performs well out of the box, many shooters choose to upgrade key components to improve trigger feel, handling, reliability, and overall shooting performance.

Ghost Inc has built a strong reputation for manufacturing high-quality Glock aftermarket parts that are trusted by competitive shooters, law enforcement professionals, and everyday firearm owners alike. Below, we break down some of the top selling Glock 43 accessories and explain how each upgrade can enhance your shooting experience.

Reduced Power Firing Pin Safety Plunger Spring

One of the easiest and most affordable trigger upgrades for the Glock 43 is the reduced power firing pin safety plunger spring. This small component plays a big role in how smooth your trigger pull feels. By lowering the resistance created by the firing pin safety system, this spring helps reduce trigger pull weight and eliminates some of the gritty feel often associated with factory Glock triggers.

Shooters often report improved trigger smoothness, cleaner break characteristics, and better overall consistency after installing this upgrade. Because it works with factory components, it’s a popular choice for those who want improved performance while maintaining factory reliability.

Benefits include:

• Smoother trigger pull
• Reduced trigger weight
• Improved consistency
• Simple drop-in installation

G42/G43/G43X/48 Ghost Edge Connector

The Ghost Edge Connector is one of the most popular trigger upgrades for Glock slim-line models including the Glock 43, 43X, and 48. This connector is engineered to reduce trigger pull weight while also smoothing out the trigger press. The result is a cleaner break and shorter reset that helps shooters maintain better control and faster follow-up shots.

Unlike many aftermarket trigger parts, the Ghost Edge Connector is designed to work seamlessly with factory Glock components. This makes it ideal for shooters who want enhanced performance without compromising safety or reliability.

Why shooters love the Ghost Edge Connector:

• Lighter trigger pull
• Smoother trigger travel
• Improved accuracy potential
• Drop-in installation with no gunsmith required

Ghost TMC Turbo Maritime Spring Cups

For shooters who demand maximum reliability, the Ghost TMC Turbo Maritime Spring Cups are a smart upgrade. These spring cups are designed to improve debris and moisture drainage from the firing pin channel. This allows water, oil, sand, and other contaminants to exit the channel more easily, helping prevent light strikes or misfires.

Originally inspired by maritime-style Glock components, these cups are ideal for shooters who train outdoors, carry in harsh environments, or simply want an added layer of reliability protection.

Key advantages include:

• Improved firing pin channel drainage
• Enhanced reliability in wet or dirty conditions
• Simple installation
• Compatible with Glock 43 platforms

6.0 lb Trigger Spring

The trigger spring plays a major role in how your Glock trigger feels and resets. The Ghost Inc 6.0 lb trigger spring is designed to improve trigger return force while maintaining a smooth pull. Many shooters prefer this spring because it creates a more positive reset, which is especially helpful during rapid fire and training sessions.

This upgrade pairs extremely well with other trigger components such as the Ghost Edge Connector and reduced power plunger spring. Together, these parts can dramatically improve trigger performance while preserving Glock’s proven reliability.

Benefits include:

• Stronger and more consistent trigger reset
• Improved trigger feel
• Better control during fast shooting
• Reliable performance for carry and range use

G43/43X/48 ESR Extended Slide Release

The factory Glock slide release can be difficult to engage, especially on slim-frame pistols like the Glock 43. The Ghost ESR Extended Slide Release provides a slightly enlarged contact surface, making it easier to manipulate the slide during reloads and malfunction clearing.

This upgrade improves ergonomics without adding unnecessary bulk. It’s a favorite among shooters who want faster reloads and more consistent slide manipulation during training or defensive use.

Why upgrade your slide release:

• Faster reloads
• Easier slide operation
• Improved ergonomics
• Low-profile design

Glock 43 9mm 6-Round Magazine

Every Glock 43 owner should have spare magazines on hand. Whether you’re heading to the range, training for defensive use, or building your everyday carry setup, extra magazines are essential. The Glock 43 9mm 6-round magazine offers factory-compatible performance with reliable feeding and durable construction.

Having multiple magazines also allows you to rotate carry mags, reduce wear, and improve training efficiency during reload drills.

Benefits of owning extra magazines:

• Improved training efficiency
• Increased reliability
• Convenient reload practice
• Essential backup for everyday carry
