The Nitty-Gritty: Diving Deeper into the Glock 43

Ejector and Extractor Enigmas

Have you ever faced those moments when your Glock 43 doesn’t quite eject casings as reliably as you’d expect? You’re not alone.

Some users have encountered pesky issues with the ejector and extractor, turning a smooth shooting session into a bit of a puzzle.


The key here is vigilance—keeping an eye on these components during your cleaning routine can catch problems before they escalate. 

Spotting signs of wear early means you can swap out for newer, perhaps even upgraded parts, ensuring your Glock 43 stays as reliable as the day you brought it home.

Reason: These quirks often trace back to the natural wear and tear of regular use, or sometimes, slight inconsistencies straight from the factory floor. It’s like wearing down your favorite pair of sneakers; eventually, they need a bit of attention or even a replacement.

Magazine Issues

Ever felt like your Glock 43’s magazine was the source of a mystery novel, with feeding issues or a puzzling fit with aftermarket extensions? This is a plot twist some users have navigated, finding themselves in a bind over magazine malfunctions.


Sticking to the script with Glock’s own magazines and recommended extensions is your best bet. Coupled with selecting ammunition that’s known to play nice with your Glock 43, you can turn those mystery moments into a story of seamless performance.

Reason: Given Glock’s meticulous design, even the smallest change can lead to unexpected chapters. And let’s not forget, ammunition isn’t one-size-fits-all. Variations in size or shape can be the culprits behind these feeding fiascos.

Trigger Trials

The Glock 43’s trigger—some love it, some wish for a rewrite. It’s a subjective saga, with feedback on the trigger’s feel varying widely among shooters.


Venturing into the world of aftermarket triggers or seeking a professional’s touch to adjust the factory setting can transform your shooting experience. It’s about finding that sweet spot where safety, reliability, and personal preference meet.

Reason: Like a complex character in a novel, the trigger’s feel is subject to personal interpretation. Factory settings aim to strike a balance but might not align with every shooter’s preference.

Jamming Issues

Jamming, while a rare twist in the Glock 43’s tale, can occasionally disrupt the flow of your shooting narrative, leaving you searching for a fix.


Jamming issues in the Glock 43 can often be resolved with a few simple steps:

Ensure Proper Maintenance: Regular cleaning and lubrication can prevent many jamming issues.

Check Your Ammo: Using high-quality, recommended ammunition can reduce feeding and jamming problems.

Inspect Magazines: Ensure your magazines are in good condition and are fully seated when inserted.

Reason: This issue often ties back to the nuances of shooting technique, such as limp wristing, or the chore of maintaining your firearm. Sometimes, the choice of ammunition plays the antagonist.

Recoil Spring Ruminations

Over time, some sharpshooters notice the recoil spring in their Glock 43 starts to lose a bit of its springiness, affecting the gun’s overall rhythm.


Keeping a close eye on the recoil spring’s condition during your maintenance routine and adhering to Glock’s replacement recommendations can ensure your Glock 43 continues to perform at its peak, making every shooting session a bestseller.

Reason: Much like any well-loved gadget or gear, parts like the recoil spring wear down, leading to a less than optimal performance saga.

Accuracy Issue

Accuracy with the Glock 43 can sometimes feel like a challenging quest, with a few users marking it as an area for improvement.


Dive into practice sessions, consider sight upgrades, and focus on honing your shooting technique. Like mastering any skill, the path to improved accuracy is through dedication and understanding the nuances of your tool.

Reason: The plot thickens when considering factors like the shooter’s skill level, how sights are aligned, and the compact size’s unique demands on precision.
