HK P30SK Problems With Their Practical Solution:

1. Slide Locking Problem:

First, the slide frequently stopped short of locking back after the last round was discharged, even with a fully loaded magazine.

This problem persisted despite continued adjustments to my grip and testing with new magazines.

Attempting to determine the root cause, owners soon realized this was not rare. Hand-loading with slightly lower pressure rounds exacerbated the issue.

A keen eye for detail is essential when fixing the slide-locking issue with the H&K P30SK.

It requires careful inspection of the grip and the positioning of the thumbs.

Often, a simple adjustment in how the thumb rests on the slide can make a massive difference in averting this common problem.

I discovered that keeping both thumbs forward instead of resting one on the slide stop can overcome the issue.

This process of mindful positioning proved vital in ensuring the slide functions as intended.

The firearm operated smoothly by taking shots with this different grip.

2. Magazine Issue:

Next, owners encountered a peculiar problem with the magazine release.

Occasionally, the release becomes loose during shooting, which is concerning as it prevents proper chambering of a new round.

This issue, linked to the unique paddle design, can be hard to pinpoint and occurs more often with sure grips.


Addressing the magazine issue with the H&K P30SK necessitates a swift response. When the magazine unexpectedly pops out during shooting, a quick tap and rack action can immediately fix the issue. It allows you to continue shooting without significant disruption.

While this workaround offers a temporary solution, finding a more permanent fix to overcome these unexpected challenges is crucial.

Making minor adjustments to your grip and staying prepared for any complications can best keep this issue at bay.

3. Feeding Problem:

While the H&K P30SK offers an undeniable thrill with its firing, its operation has occasional glitches.

One such issue arises when inserting a magazine, as the slide may fail to feed the first round.

This inconsistency can catch shooters off guard and needs to be addressed to ensure smooth operation.


Addressing the feeding problem seemed complicated, but slightly polishing the magazine feed lips proved effective.

Cleaning with a toothbrush and rag worked wonders, and changing how owners loaded the magazine made a huge difference in functionality.

4. Issues with the Slide Release:

Next, I discovered an issue that caught me off guard. The slide release had been acting smoothly. Suddenly, it puzzled as it seemed to falter.

The owners examined the gun closely to identify the culprit.

Upon closer inspection, they discovered some damage that had initiated in the frame, affecting the shooting accuracy and overall performance.


Careful tinkering was the secret sauce that led to this solution. After detaching and inspecting the slide release lever, they discovered a bent spring due to excessive force.

After a simple replacement, the firearm now operates flawlessly. It underscores the importance of maintenance, just like in Taurus Curve.

5. Trigger Problem:

Next, there was a concerning issue: fitting a GrayGuns flat trigger modification.

However, owners soon noticed a distinct issue with the trigger’s curvature at the top.

Upon pressing the trigger back, they felt slight resistance near the guard. A careful inspection led them to believe that the paint on the guard was contributing to the problem.


In search of a fix for the nuanced issue with my H&K P30SK trigger, owners explored previous solutions and contacted Gray Guns to discuss the matter.

They suggested trying to hit the interior of the trigger guard with 1000-grit sandpaper for a finer finish.

My Final Conclusion:

My research with the H&K P30SK firearm has been an exploration of its array of positive features and mechanical nuances.

It has demonstrated robust performance overall despite some noticeable problems and challenges, such as slide locking, feeding, magazine release, and trigger modification.

However, there are straightforward solutions that showcase the firearm’s flexibility and adaptability.

My Friends Feedback:

Reflecting on my friend’s experience with the P30SK V3 over the past summer, I consider its place in the USP lineup alongside models like the VP9 and Mark 23.

As a smaller option for everyday carry (EDC) compared to the USP 2000SK, its flush magazine plate and pinky support extension offer a balance of grip and size.

However, despite its compact nature, inconsistent trigger pulls led to frustratingly awful groupings during range trips.

The trigger issue prompted months of online searching and advice-seeking from the specialists.

Despite attempts to adjust my grip and shooting technique, the problem persisted.

Even after considering solutions like replacing worn parts and modifying the trigger, he was still frustrated and uncertain about the HK P30SK & Taurus PT 738 Problems.

While it has strengths, this pistol may not fit perfectly for every shooter.

Common Questions Asked About HK P30SK Problems:

How accurate is the HK P30SK?

In a unique circumstance, testers found the P30SK to deliver exceptional accuracy, ranking it second best with a group size of 44 mm using GECO Hexagon ammunition at a distance of 15 meters, resulting in a deduction of 6 points.

Does the HK P30SK have a Decocker?

All P30 pistols with traditional DA/SA triggers feature a manual decocking lever for classic hammer-down carry. Additionally, the availability of an ambidextrous thumb safety offers the choice between hammer-down carry or “cocked and locked” single-action carry.

What is the sight radius of the HK P30SK?

The sight radius for the P30SK, as provided by HK, measures 5.35 inches. At a distance of 25 yards (900 inches), a deviation of 6 inches translates to a necessary adjustment of the front sight height by 0.0357 inches or 0.9mm, based on the principle of similar triangles. HK Parts specifies the stock front sight height as 6.3mm.

Are HK guns reliable?

These firearms are generally highly reliable once they’ve undergone a break-in period and are firing ammunition suited to the recoil spring’s strength. If you’re experiencing smoke stack jams, consider using heavier bullets or +P ammunition, provided your firearm can safely handle it.

Where is the HK P30SK made? 

The P30SK is crafted and produced in Oberndorf, Germany.

What is the difference between HK P30 and P30SK?

The P30 model falls in the middle ground with a 3.85-inch barrel length yet maintains the same grip height as the P30L. H&K opts out of producing compact firearms altogether, instead offering the P30SK (subcompact) with a shorter 3.27-inch barrel and reduced grip height.
