I have tried everything to get the gun to run reliably. It has NEVER cycled a complete mag without at least one FTF. In disassembling and working on the weapon, I'm shocked at the cheap, shoddy design and fabrication. It's built with all the precision of a 1930s hay baler.......well, that's not fair because the baler might actually work some of the time. I won't even try to sell it because I don't want to be responsible for selling a defective product. It holds a unique place of shame in my gun closet. Goes to show you get what you pay for. It isn't a Sig or a Colt or an FN..........It's a Kel Tec. And I will never buy another Kel Tec product.

What kind of .40 ammo are you using or trying to use? Gen 1 or Gen 2 S2K? What mags are you using? Curious as I have quite a few KT products and I have never had an issue over last 10 years.

I have 2 .40 S2K one Glock one S&W both Gen 2 and no issues so far!

Well....guess that says it all. Join up and make your first post in a gun - fan specific forum...and it's nothing but a big gripe.

Are you finished now? Don't want to ask any questions? Like maybe what can be done to make your sub run better? Want to offer any pictures? Give us some more detail so we can help? Ask for any tips or hints? Advice?

You're definitely just gonna drop that post in here and walk away? Because if you are, I'm going to delete it...we really only want posts from people willing to put some time and effort into being a Member of KTOG.

No it's not a Sig, colt etc not by a long shot but you knew that when you bought it. Wonder what the price tag on a HK folding PCC would be? I am not shy about talking about the warts and trying to sort things out.... it is only reasonable to expect the gun to function. What have you done to fix it? Have you contacted Kel Tec? What ammo have you tried? Are you the first owner? Here's a big question what magazines are you using/ have you tried others?
If you want to make this work there are a couple guys on here that can point you in the right direction. If your too sick of the gun you will have no trouble finding someone to relieve you of your burden here, guilt free

I took my new-to-me Glock mag Gen1 .40 to the range yesterday and had zero problems. I didn't put that many rounds through it (100ish) but it certainly works fine for me. This was with cheap, fairly low power, ammo.

I see that you have been a member for more than a year ... Welcome!

As for your particular S2K experience, I recommend that you
return it to Kel-Tec for evaluation, upgrades & warranty repair.

My gen 2 .40 sub functions fine with anything i stuff in her, you just have a lemon. My other 2 kel tec's , a 9mm gen 2 sub 2000 (over 1k no failures) and RDB (400+ no failures) worked fine right out of the box also.

 

[Billy-B-Goode]

All responders,
Thanks for the positive feedback. Belated apologies for the "gripes-only" post. Had a real wedgie after multiple failures to correct the problem. I do appreciate the offers to help. I will disassemble the old girl one more time and take some pictures this time. Maybe there's a path forward after all. Thanks again.

I can appreciate your desire to identify & solve the problem(s) yourself, but you have a warranty, and Kel-Tec has a staff of service technicians that will do this for you... they have all of the parts on hand, and there are upgrades that you may not even be aware of.

Give them a chance to make you a happy S2K owner.

I have a Gen 2 40cal SUB2k and had a few FTE issues at first. Really lost confidence in the gun. Would not even consider depending on it to defend myself or family. I found this forum, read through several posts from people that had similar experiences of varying degrees. Got some good ideas on how to improve the guns performance. I am, by no means, a gunsmith...but I like to tinker. After some tinkering, replacing the bolt and charging handle to add some weight and slow it down a bit, I am very happy with what I ended up with. I have now gone about 2500 rounds without a hiccup or failure in any way. I am definitely more confident with the reliability of this gun now.

The heavy brass bolt and sumo handle are "must haves" for a .40 sub2000. Keltec really needs to add at least 100g to the .40 bolt assembly from the factory.

Opinion. Both my Sub 9-40 and my Gen 1 Sub2k are over 10 years old. Once my sub2K reached break in it hasn't been a problem, and the Sub 9-40 never has. The brass bolt weight is a nice addition, as well as the Sumo handle I would assume. But please don't phrase them as "Must haves" for the weapon to work. Lots of new members may read that as "Wow, I just bought this thing and I already have to buy more parts to make it work?". They have worked fine as designed for over 20 years now.

All anybody gives on this forum is their opinion. My experience, and apparently others as well, is that they made significant improvements to recoil reduction, brass condition , cleaner shooting (less residue), and reliability in many cases. More importantly the physics aligns with the opinion. I've never heard anyone on here regret installing them and most who have are ecstatic they did. Ok, to everyone out there, they are "highly recommended" upgrades to all who own a .40 "sub 2000" based upon my experiences and those of several others.

I think this is a fair point.

I'm very guilty of saying that installing an aluminum trigger is a "must have", but obviously the gun functions fine with the stock one.

That's all I ask. I just don't want new members thinking "Oh my God, what have I got into?". It just seems like we've had a lot of newer members buying lots of parts and adding them before they even shoot the thing. It's my humble opinion that any new gun should be shot through break in in its factory issued condition. That way if there are any problems they are easier to track down without having to take into account the new stuff that's been added.

I love that Kel-tec has made the heavier bolt weight, and I'm really happy to see more aftermarket support like the Sumo handle, triggers, and sights. All of my Subs have been in 40 S&W and I'll admit they are shoulder thumpers as sold. If a little extra mass reduces that bruising I'm all for it. I just don't want people to think it is required to make the gun run properly.

 

[lab-rat]

I added the heavy bolt from Kel-Tec, and the Sumo charging handle to my .40 cal Subby and really like the reduced recoil and smoother feel to the action. Just my 2 cents. Do what ever you want to do.

 

[Junkie]

Oddly enough my .40 with stock bolt and long charging handle seemed to have significantly less recoil than a 9mm Kriss Vector that someone else had. It's also shorter and lighter... sure makes me wonder what the point of the Vector is, especially given the price.

 

[jimsts]

I shoot mine every week in uspsa, runs perfect.

 

[TNTRAILERTRASH]

I wonder about this product http://www.tacticoolproducts.com/sub-2000buffercylinder/ if things don't get stupid crazy a 40 would be on my list. Reducing the recoil on my 9 would be OK.

I tried 2 of these buffers prior to going with heavy bolt/sumo handle combo. Both buffers started to disintegrate within a couple hundred rounds. They refunded my money so no complaints with customer service.
