Top 4 Kel-Tec Sub 2000 Gen 2 Problems & Solutions

1. Barrel Problem

Let’s kick things off with the barrel problem. This is a serious one. The issue came up when barrels started rupturing during firing. 

Yeah, you heard that right—rupturing! That’s not something you want happening when you’re out and about. Kel Tec did some investigating and found out the problem was linked to barrels that weren’t correctly tempered. 

This made the barrels weak and prone to failure, a big no-no in the firearm world.


Now, here’s the good part. Kel Tec didn’t sit around; they took immediate action. They issued a recall and pinpointed the problem to a specific batch of barrels. 

So, what’s the solution? I sent mine back through the recall process, and it was smooth sailing. Kel Tec replaced the barrel free of charge. No more worrying about a ruptured barrel for me. 

If you have this issue, getting your weapon in for that recall is crucial. No beating around the bush; send it in and get it sorted. The replacement process is hassle-free and should resolve the problem.

2. Problem with the Trigger Mechanism 

Alright, moving on to another irksome issue: the trigger. Man, this trigger had me scratching my head. It’s set at a factory pull of nine and a half pounds, which is way too heavy for most people, including me. 

But that’s not the only thing. The trigger felt spongy, almost like it had two break points. You’d pull it back to a certain point, expecting it to break, but nope! You have to pull even more. 

This long, heavy, and unclear pull seriously affects your accuracy, especially if you’re trying to hit something at a distance.


So, what did I do to fix this? I went for some aftermarket springs. These are easily available, and installing them is a cinch. With the new springs, my trigger pull dropped to under five pounds. 

What a relief! It feels so much better and lighter. And most importantly, it’s not messing with my accuracy anymore. 

You might be using the Kel-Tec Sub-2000 for close-range stuff, but if you want to take longer shots, a good trigger is a must. Switching out those factory springs for aftermarket ones is the way to go, trust me.

3. Firing Problem 

Okay, let’s get into the firing issue. This one’s a big deal, especially when you’re in a situation where you need your weapon to perform consistently. 

I noticed that sometimes the gun wouldn’t fire as smoothly as I’d like. It would jam up or misfire, creating a moment of panic. Trust me, in the field, you don’t have time for such problems.

This kind of unreliable firing doesn’t just ruin your shot but can also make you lose trust in your firearm. It’s disheartening when you’re aiming, you pull the trigger, and it just doesn’t go as planned.


So, here’s what I did. I took a closer look and found that the problem was often linked to the ammunition being used. 

Opting for higher-quality ammo made a world of difference. I also regularly cleaned and lubricated the firing pin and chamber. 

Doing these two things improved the firing reliability considerably. No more surprise misfires or jams for me. If you’re experiencing similar issues, take the time to invest in quality ammo and perform regular maintenance. 

A clean, well-maintained gun with good ammo is a dependable gun.

4. Heavy Recoil Spring

Let’s tackle the last issue I ran into: the heavy recoil spring. This isn’t just a minor inconvenience; it can really affect how you handle the weapon. 

Cocking the gun was far more strenuous than it needed to be, thanks to the overly stiff spring. The charging handle is oddly positioned, too, which doesn’t help. 

You really have to get a good grip and put some muscle into it to cocked the weapon. And let’s be honest, in a tense situation, the last thing you want is to struggle with your firearm.


Here’s how I addressed this issue. First off, I tried the rubber tubing trick. I slipped some rubber tubing over the charging handle. 

While it didn’t make the spring any lighter, it reduced the felt pressure on my finger, making it less of a pain. But I went for an aftermarket extended bolt handle for a more permanent fix. 

It gave me a better grip and made the whole cocking process less strenuous. If you’re having trouble with a stiff recoil spring, I highly recommend going for one of these extended bolt handles. It’s a game-changer.

Final Verdict

Alright, let’s wrap this up. After spending considerable time in the field with the Kel-Tec Sub 2000 Gen 2, it’s clear the firearm has its flaws. We’re talking about a heavy recoil spring, barrel issues, finicky triggers, and firing issues.

 But hold on a second; it’s not all doom and gloom. What’s awesome about this gun is how most of these issues have viable solutions. 

Whether it’s sending the gun back for a recall, switching out trigger springs, or even just using higher-quality ammo, you can solve these problems. 

So, while the firearm has its shortcomings, they aren’t deal-breakers. Fix ’em up, and you’ve got yourself a pretty reliable and fun piece of hardware.
