While testing the HK 45C in various conditions, I’ve come to appreciate its ruggedness and reliability. However, no piece of machinery is without its challenges, and the HK 45C is no exception.
Throughout my experience, I’ve encountered a few common HK 45C problems that seemed to crop up more than once.
Now, I’m not here to throw shade on the HK 45C. Far from it. My aim is to share the solutions that have worked for me in hopes that they’ll help others facing similar troubles.
| Problem | Solution |
| Slide Lock Lever Issue | Replace slide lock spring for proper tension and adjust or replace magazine follower for correct slide lock engagement. |
| Hammer Follows the Slide | Adjust engagement between the sear and the hammer; replace worn components in the fire control group. |
| Problem with Magazine Follower | Disassemble and inspect followers for wear; replace if necessary or adjust follower’s tab for better slide lock contact. |
Top 3 HK 45C Issues & Their Solutions
1. Slide Lock Lever Issue
A common issue I encountered with the HK45C was the slide not locking open after the last round was fired. This problem persisted regardless of my shooting style or the ammunition used.
Initially, I considered factors like my grip or the possibility of inadvertently hitting the slide release during firing.
After experimenting with different grips and ensuring my thumbs were clear of the slide release, the problem persisted, leading me to conclude that it wasn’t just a matter of handling or ammunition type.
Solution
Upon closer inspection and research, I found that the slide lock lever issue often stems from either wear and tear of the slide lock mechanism or improper engagement between the magazine follower and the slide lock.
The solution that worked for me involved a two-pronged approach. First, I replaced the slide lock spring to ensure it had enough tension to engage properly.
Second, I inspected and replaced the magazine follower on magazines failing to properly engage the slide lock.
2. Hammer Follows the Slide
Another issue I experienced was the hammer following the slide down without engaging the sear, resulting in the hammer being in the forward position after each shot.
This problem was particularly noticeable when I held the trigger to the rear while racking the slide on an unloaded gun. This malfunction prevented the firearm from properly resetting to single-action mode, affecting the consistency and predictability of subsequent shots.
Solution
Solving this problem required a detailed examination of the fire control group, particularly the interaction between the hammer, sear, and disconnector.
The most effective solution involved adjusting the engagement between the sear and the hammer.
This adjustment can be delicate and should ideally be performed by a qualified gunsmith to ensure that it’s done correctly and safely.
Replacing worn components in the fire control group, such as the sear or hammer springs, can also prevent hammer follow by ensuring stronger, more reliable engagement.
3. Problem with the Magazine Follower
In my time with the HK45C, I also ran into issues where the magazine follower didn’t properly engage with the slide lock, leading to the slide not staying open after the last round.
This perplexing problem seemed unrelated to the type of ammunition used or my shooting technique.
Upon closer examination, it became clear that the issue was with the magazine itself, specifically the interaction between the follower and the slide lock mechanism.
Solution
The solution that worked for me was twofold. First, I disassembled the magazines to inspect the followers for wear or damage. Replacing the worn followers with new ones immediately resolved the issue in a couple of cases.
After making these adjustments, the magazines reliably engaged the slide lock after the last round. It’s a simple fix that requires minimal tools and can significantly improve the reliability of your HK45C.
