Magpul Magwell Problems

There’s a “non-locking mag” issue with 90% of OEM mags. Gen 3 does not clear the Magpul’s Enhanced Magwell.

It blocks the mags from the full insert and prevents them from catching.

Possible Reasons

The gap between the base plate and the grip on the G19 is negligibly small if any. This void is too densely filled by the Magpul mag well.

To function on the gun, it would need to be as thin as paper. It is an abject design failure.

The Fix

The issue is mainly with the Magpul. Although they claim to have fixed the issue, some guns still demonstrate this problem.

A change of magazines is what can fix the issue. Some ambidextrous magazines work fine.

Jamming Issue

Failure to feed the JHP ammo reloads, or factory ammunition is evident in Glock 19 gen 3 firearms.

Additionally, the bullet’s nose strikes the bottom of the ramp.

Possible Reasons

The Glock 19 magazine’s exact capacity of 15 rounds is the issue.

You might see that the fifteenth round sinks more forcefully than the others and that you are unable to lower it any further.

It is a design issue really.

The Fix

Substitute a stock spring for the stock recoil spring. Avoid limp wristing as the gun is too sensitive for that.

The best way to handle a Glock-19 is to fill every magazine with 14 rounds aside from the one you’ll carry inside the weapon.

With the slide locked back, load that one up to 15 rounds and insert it into the firearm.

Use better ammunition, such as the 147gr HST and similar ammo.

Failure to Extract

You will be struck by hot casing on your face, forehead, or any other area of skin due to this issue.

Possible Reasons

The breech face and extractor hook on the Glock extractor are separated by a wide space.

The extractor may not function properly if it is gummed up, too tight, and has a weak extractor spring because the fired case won’t be firmly held.

The Fix

Verify the strength of the extractor spring. When you experience issues, replace the spring and bearing. Following that, try these things:

  • Grip Tighter
  • Use a recoil spring that is 2 pounds lighter or use hotter ammo.
  • Purchase an APEX extractor and the two OEM components they suggest if nothing works.

Trigger Problem

The Glock 19 Gen 3 requires more force to pull the trigger.

The trigger needs to be squeezed harder than ever right before it releases the firing pin at the end of the pull.

Possible Reasons

Due to wear on the trigger bar and connector, the trigger bar might sit too high and rub against the connector.

The Fix

A drop of oil should be applied to the connector so that it touches the area where the trigger bar and the connector touch.

Consider using trigger kits that only (or primarily) use OEM components to replace the trigger.

Slide Lock Spring

The slide lock spring is prone to failing. The spring’s slot tapers and prevents the flat-style spring from fitting in there.

Possible Reasons

The spring cannot compress past the tapered part of the frame on the right. There may be several parts failing including the spring.

The Fix

Replace the Slide Lock Spring. Also, replace the recoil spring assembly, slide stop lever (has integral wire spring), coil trigger spring and firing pin spring.

User Feedback on Glock 19 Gen 3

Glock Gen 3s are just as good, if not better, than Gen 4 or Gen 5s. The easier to modify recoil spring system in the gen 3 line is typically preferred by people who shoot suppressed.

Of all Glocks, the Gen 3 Glock 19 has the best trigger. It’s also fairly accurate.

The third generation Glock pistols have undergone the most extensive field testing and combat validation of any Glock.

Additionally, the infamous “BTF” Glocks—the MIM extractors—that Glock GmbH/Inc. used on later Model 19s are absolute garbage! So you are safe with a 3rd gen gun there!

Instead of a double spring assembly, the Gen 3 Glocks have a single spring assembly for the recoil. The double is and was more likely to become clogged with sand, which would impair its functionality.

Moreover, Glock got it right with the Gen3 before making a mistake with the Gen 4 sandpaper grips.

So I’d say the Gen 3 Glock 19 is a win-win!

Top 3 Alternative Guns of Glock 19 Gen 3

Based on comparing the specs, features, practicality, and performance, I have found the 3 best alternatives to Glock 19 Gen 3. 

Glock 19X

As long as they are using the same magazine, the G19 and G19X have the same capacity. The G19X arrives with the maritime Firing Pin Spring Cups’ magical pixie dust. You don’t want to miss out on that!

Glock 17

Get the 17 if you find the longer grip to be helpful to you. Additionally, the Glock 19 accepts 17-round magazines.

PSA Dagger

They resemble a Gen 3 Glock and employ Glock magazines. Compared to a Glock 19 or a P80 build, the frame is more comfortable to hold. The only drawbacks might be a few instances of pins coming loose.

Frequently Asked Questions (FAQs)

Is the frame of a Glock 19 Gen 5 and a Glock 19 Gen 3 same?

Yes. The frame material is the same just a different texture. There are no finger grooves.

What is the difference between Glock 19 Gen 3 and Gen 5 magazines?

The Gen 5’a magazine release is larger than the Gen 3’s.

How to buy the better models of Glock 19 Gen 3?

Look for a used Model 19 with a serial number prefix between “C” and “L” if you want to buy the better G19 Gen 3.

Are there serrations on the 19 Gen 3 slide?


Where is the Glock 19 Gen 3 legal?

California, USA.


The G19 Gen 3 is the best all-around sidearm in the world because it can do everything.

The third gens still have a Glockiness to them. They have a sort of “refined” quality to them.

Furthermore, none of the models of the Gen 3 have many issues. They are quite the strong guns.

Additionally, they would be excellent for an EDC. Its continued dependability and durability are demonstrated by the military’s and law enforcement’s increased adoption.

I would recommend you to go for this one, especially if you are in California!
