Magazine Problems

The magazine moves freely inside the magazine well after releasing from it, ready to fall out.

There could be damage to the magazine as a result of the magazine release, where the plastic on the notch starts to peel away.

Magazine Problems

Possible Reasons

The retention of the magazine in this gun is a serious issue. Between the mag well and the mag, there is a sizable space.

This is made clear when loading 10 rounds.

The Fix

For an issue as serious as this, contact Glock. Ask them to fix the magazine release problem for you.

Additionally, you can do a few more things. To chamber a round, fully load the magazine, slide back into position, lock it, and then insert it.

Purchase a 9-round magazine and practice loading it. Fill your 10rds to them and let them set. They’ll become easier.

Jamming Issue

After around 50 rounds at the range, the Glock fails to fire and jams. This happens more than once.

Possible Reasons

It can be a cleaning issue with the trigger bar, extractor, or port. If this occurs with your rental gun, it can be because of unkept equipment.

The problem may also result from weak gripping or limp wristing during firing.

The Fix

Field strip and clean the gun. Then lube it well.

Replace any of the mentioned parts that may have a problem. Learn to run tests to identify the source of the issue.

Additionally, focus on your limp wristing. After several rounds, the gun becomes easier to shoot.

Failure to Feed

A feeding issue occurs particularly in the last round of the magazine. It would happen around 30-45% of the time.

The 10th round tries to follow behind the 9th round, which noses up and jams against the top edge of the chamber.

Possible Reasons

It can happen due to:

  • Lead or copper jacketed ammo or Armscor brass cased ball ammo, Federal 230 gr. Hydra-Shok JHP etc.
  • Factory or reloads.
  • Feed ramp burrs
  • Magazine problem or worn/spread magazine lips. (Disassemble the magazines and check the tubes and followers for burrs or flashing).
  • Mag Springs

The Fix

With a quality dry lube, clean and lubricate the interior of the mag tubes. Change the mag springs if the issue continues.

Use high power and good quality ammo. Remington UMC FMJ loads, and Winchester White Box are good.

If you find burrs, polish the ramp or take it to an expert gunsmith at the lack of confidence!

Slide Problem

The slide cannot be pulled back to chamber the first round when a fully loaded mag (13 rounds) is inserted.

Possible Reasons

This gun’s magazine springs occasionally become “stiff.” This is the problem. Additionally, it’s possible that the RSA strayed a little away from its groove.

The Fix

Avoid forcing the final round when loading a magazine. The pistol may in fact “lock up” as a result of it.

Turn the pistol over (barrel down) and quickly tap it against your knee. This should put that RSA back in place.

Alternately, after releasing the slide lock, draw the slide forward while pressing the slide and frame together at the trigger guard.

Trigger Bar Issues

There’s a failure to return to battery issue due to the trigger bar partially scraping against the slide.

Possible Reasons

The triggers in the Gen 4 are terrible. It appears that the Gen 4 trigger bars have been upgraded.

A weak recoil spring may prevent the battery from entering. Regardless of generation, G30s have always had the bulge on the trigger bar.

When fully loaded, the magazines are also very stiff, which significantly increases resistance when racking the slide.

The Fix

Request a newer trigger bar by calling Glock. Your best option is to download the magazines one at a time until the pistol and magazines start to loosen up.

User Feedback on Glock 30 Gen 4

According to the users, the Glock 30 Gen 4 is a wonderful handgun. It is quick to become people’s new EDC for sure.

Users also discover that they are surprisingly accurate using it. Additionally, all the criticism of Glock’s factory sights is utter nonsense!

Yes, night sights are better. And you could change them. But the factory ones are actually rather good.

Additionally, it won’t weigh too much and won’t be too tough to conceal for an all-day carry for a regular man. Lighter/smaller handguns of the same caliber might be a little harder to keep on point without that bulky slide from the larger 45’s.

In my opinion, users love the Glock 30gen 4 for themselves!

Top 3 Alternative Guns of Glock 30 Gen 4

Based on comparing the specs, features, practicality, and performance, I have found the 3 best alternatives to Glock 30 Gen 4. 

SR1911 CMD

The 1911 is thinner, thus it might be simpler to conceal. It might be a little “easier” than the Glock 30 because it is probably a little lighter, but the problem should be lessened with a sturdy belt or holster.

The two firearms’ operating systems, however, are entirely different.

Glock 42

The G21 is a sizable firearm. Excellent firearm, however it is difficult to conceal. G21 is perhaps the best option for home defense.

Taurus G3c

Taurus has been around for a while, and their guns have become better over time in terms of quality and accuracy.

The mag release and sights are functional but small. They are no SIG or Colt anyway!

It is the heaviest and “thickest” rifle you will often carry concealed when fully loaded (10 or 11 rounds).

It consumes anything that you feed it and cries out for more. Although it’s a hideous Glock. It is thicker and heavier than a G19.
