Slide Problems
The Glock 19 Gen 5 stock doesn’t always lock back on empty.
The slide is also very difficult to rack back. It gets stuck, especially 0.1-0.25 inches back. As if something is holding the slide.
Possible Reasons
The trigger housing’s top, the slide release or the trigger bar could be the reason. Look for rub marks on the slide’s underside or its action parts using a small flashlight.
The safety plunger in the slide is depressed by the trigger bar, which operates during the first 1/4″ of slide movement. Issues can be caused by a damaged trigger bar.
It could possibly be a misaligned connector.
The Fix
Take the Glock to a gunsmith or send it to Glock to find out the issue.
Pretty sure you will need to replace the trigger bar, adjust the trigger housing and work with the slide release.
Fix the alignment of the connector too.
Ejection Issue
The ejection is very weak. The rounds consistently hit the shoulder, forearm as well as head. The casings may remain stuck.
Possible Reasons
A weak ejector on the Glock 19 gen 5 is the issue here.
Additionally, the new cut to the breach face for the Gen 5 guns alters how the extractor grabs the round.
The Fix
Send it to Glock, let them fix the problem. Then, if you’d like, upgrade the gun.
You can install the Glock 19X ejector. Additionally, you should try the Apex Failure Resistant Extractor.
MOS Problem
Certain optics don’t work well with the weapon. With the Glock 19 Gen 5 and Optics like Trijicon (RMR type optics), you might experience a problem with searching for the red dot.
Possible Reasons
For some optics, the MOS model is not milled deeply enough.
Certain optics cannot be used with the MOS due to its plate and screw size dimensions not fitting.
The Fix
If you want one specifically as an optic gun, I recommend purchasing the standard Gen5 and having it custom-milled for your preferred optic.
Otherwise, Holosun fits great with the MOS on this one!
Trigger Problem
Although the trigger in the Gen 5 is better, it becomes somewhat unresponsive after a while.
When racking the slide, the trigger occasionally goes dead.
Possible Reasons
The front of the housing on the 5 has a spring, and an S clip is attached to the front of the sear.
The striker only needs to hit this S clip for it to fall off. This causes trigger issues.
The Fix
Before racking the slide lock, move the slide
If that doesn’t work, a trip back to Glock is required!
But make sure the gun is clean and lubed and then if the problem exists, going back to Glock it is!
Barrel Issues
The Glock 19 Gen 5 barrel wears out very easily and rapidly.
Possible Reasons
This is a problem with the Gen 5 Marksman barrels. This is typical wear on fifth-generation pistols.
The barrel itself is not being harmed by this; only the black finish wears out.
The Fix
Wear can be decreased by applying some oil to the barrel’s exterior. Even without a finish, these barrels are incredibly hard and corrosion-resistant.
Do not, however, try to swap the barrels.
User Feedback on Glock 19 Gen 5
Most users feel that the Glock 19 Gen 5 is a safe bet. Perfect size, capacity, and a long track record of dependability spanning more than 30 years.
It’s a fantastic weapon that is ideal as a conceal, home defense, and any other use you might have. The Glock 19 Gen 5 was designed specifically for the nine-millimeter round.
The MOS mounting system is less reliable than a direct milled mount, though. In comparison to the OEM Glock MOS plate, there are some better mounting options available.
However, the Gen 5’s firing pin safety design is superior to the Gen 4’s. Compared to the Gen 4, it also feels nicer in the hand.
Several people complain about the Gen 5 barrels’ accelerated wear. The DLC coating on the slide making the surfaces of the slide harder is what causes this.
Additionally, some people feel that the Gen 5 trigger is not quite as crisp as the Glock 19 Gen 4 trigger.
Nevertheless, given everything, it’s a pretty popular gun to own!
Top 3 Alternative Guns of Glock 19 Gen 5
Based on comparing the specs, features, practicality, and performance, I have found the 3 best alternatives to Glock 19 Gen 5.
Canik TP9SF Elite
It is a gorgeous gun with the gray slide. Even better than the Walther PPQ.
It’s trigger is unquestionably the best on a Striker-fired pistol. The Canik is typically more accurate to shoot than the Glock 19 Gen 5.
SIG 320
It is a reliable and safe gun because of the manual safety. However, the problem is with the SIG’s terrible customer service, gone worse over the years. The modularity of this may appeal to you more than the Glock’s.
S&W M&P 2.0 Compact
They are essentially the same as concealed weapons. However, the M&P feels better in the hand.
This one has a better ergonomic design too. In addition, the M&P trigger clearly outperforms the Glock 19 Gen 5 trigger.
