Top 5 Problems & Solutions for the CZ 75 SP-01

1. Slide Problem

So, let’s dive right into the first issue: the slide lock. I took my CZ 75 SP-01 to the range and noticed something off. 

After firing a few rounds, the slide didn’t lock back. Initially, I thought it might be me, but the issue persisted. What a bummer! Slide-lock issues are no joke, especially if you’re in a situation where you’re counting on that firearm to perform flawlessly.


Now for the good news. After some tinkering, I identified that the recoil spring had seen better days. I swapped it out for a new one, and guess what? Problem solved. It’s not rocket science; you just need to keep an eye on that recoil spring. 

But wait, there’s more! I also noticed my extractor was worn out. So, I went ahead and replaced that as well. 

For good measure, I lubed the slide rails with some gun oil. If you’re facing the same issue, I’d say start with these parts. 

Trust me, a new recoil spring and extractor can make a world of difference.

2. Hammer Strike Issue

Let’s get to the next issue I noticed while firing rounds: the hammer strike. It’s weird, you know? 

You pull the trigger, and the hammer falls, but nothing happens. Talk about a frustrating experience! On my CZ 75 SP-01, this seemed to happen more often than I’d have liked. 

And you don’t want to find yourself in a situation where your gun’s hammer is playing games with you. It’s an issue that I came across during my time at the range, and let me tell you, it’s as annoying as it sounds.


So, what’s the fix here? First thing first, I checked my firing pin spring, and sure enough, it was bent. Replacing it was a no-brainer. And bingo, that cleared up a lot of the issues. But wait, there was also the matter of the sear’s tension. 

After some adjustment, the hammer strikes were a thing of the past. A regular cleaning and maintenance routine also helps heaps. If you find yourself with a similar issue, start with the firing pin spring and sear tension. 

Believe me, you don’t want to take a chance with something as important as this.

3. Extraction Problem

Now, let’s get down to the next big issue I bumped into: failure to extract. I was out in the field, trying to get a feel for the gun, and all of a sudden, it wouldn’t eject the spent casings. 

Talk about a buzzkill! Whether I was live-firing or doing some dry-fire practice, the problem was the same. 

This snag isn’t just a minor inconvenience; it disrupts the whole flow and makes you lose trust in your firearm.


So, what’s the fix? First off, I tackled the weak extractor spring. Switching it for a stronger one made a considerable difference. Yep, sometimes it’s that simple. Next up is the worn extractor claw. 

Replacing it made my CZ 75 SP-01 as good as new. Don’t forget the chamber; a dirty one is a recipe for trouble. A bit of cleaning solvent did the trick for me. 

4. Trigger Issue

Alright, another thing that irked me was the heavy trigger pull. I was out there, lining up my shots, and then I noticed the struggle. I could feel that extra weight every time I pulled the trigger. Not only did it feel weird, but it also messed with my shooting accuracy. 

When you’re trying to get a consistent performance, this kind of issue is more than annoying; it’s disruptive.


So, how did I fix this? The first thing I tackled was the sear engagement. With a bit of fine-tuning, I got it to engage just right with the hammer. 

It’s a tiny adjustment but can make a world of difference. Next up was the worn-out trigger return spring. Slapping in a new one made pulling the trigger much smoother. And lastly, the hammer spring. Replacing it with a lighter one? Game-changer. 

All these fixes didn’t just make the trigger pull better; they made shooting this gun feel natural again. If you’ve got the same issues, sorting these out will make your CZ 75 SP-01 feel like a new weapon.

5. Failure to Lock Back

So, I’m out in the field, and guess what happens? My CZ 75 SP-01 refuses to lock back after the last round. Yep, you heard that right. I fire off that final shot, and instead of locking back like it should, the slide just kind of sits there. 

Annoying, to say the least. This doesn’t just mess up the flow; it makes you second-guess the reliability of your sidearm. Not cool, right? So, I narrowed it down and found out that my magazine was the main reason for this problem.


Now, on to the fix. First things first, I ditched my old magazines. No more messing around with unreliable gear.

I got myself some top-grade, high-quality magazines. Popped them in, and guess what? Problem solved. The slide locked back just like it was supposed to every single time.

If you’ve been dealing with the same pesky problem, do yourself a favor and invest in some quality magazines. It’ll sort out the failure-to-lock-back issue and make your shooting experience a whole lot better.


The CZ 75 SP-01 is undoubtedly a strong contender in the world of firearms. Its design is impeccable, and its performance mostly lives up to the hype. 

But let’s be real: no gun is perfect, and this one is no exception. I’ve run into my share of issues: slide problems, hammer strike inconsistencies, extraction failures, trigger hitches, and even a failure to lock back. 

Most of these problems can be addressed with some straightforward solutions. So, if you’re looking to get the most out of this firearm, a bit of proactive maintenance can go a long way.
