New to me keltec sub 2K 9mm gen 2

I just picked up a Sub 2K, at a steal price. Just couldn't resist, It was sold as NIB but that became a good bargining point, it obviously was not. One range trip, and a "detail strip" bath has me sold on the virtues of this one as a truck / SHTF gun.

It shoots reliably, 2 MOA @ 50 yards, ate everything I threw at it. (including my 115/147 Gr. handloads,) Fast cycle / lock time.

Down checks,

trigger is heavy and mushey (already ordered an aluminum trigger and spring kit)

Bolt handle effort seems too heavy / sticky don't know why. Easy fix? has anybody tried the 2 finger bolt handle? good, bad, indifferent?

Recoil is sharp, bolt tube/body smacks my cheekbone, annoying, not a show stopper. Can anybody recommend an effective muzzle brake ?

Iron sights and my old eyes are not gonna get on too well, will somebody recommend a small red dot/QD that works for you? (I know it must be removed to use the folding feature. thus the QD, NBD to me)

I'm pretty sure, with a little help, this one's gonna grow on me, it's just too much fun not to plink with it...

Let the games begin.

sounds like a fun gun but the ones I've seen have a price tag with $100 of a budget ar15. so I can't talk myself into one.

I bought mine last spring. I shoot my 9mm 124gn handloads reliably. It also shoots hollow points as well. I use a Sig Romeo 5 on a UTG quick release base. It stores on the lower picatinny rail. I find it holds zero as well as I can shoot.
If you want to make modifications to it, MCARBO has many options. I have left mine stock so far.

The greatest feature of the carbine is it folds to about 16" and fits in my backpack. My buddies 9mm AR won't do that.

I too put off getting one for a while. First run guns were getting upwards of 350.00 over MSRP, Way out of reach on my retired fixed income.

I "back burnered" my purchase dreams. Several years later, I ran across this Gen 2. It was offered ANIB for $300. It was obviously used, skinned up bolt and very dirty bore, but otherwise intact. At the same show, NIB dealer guns were bringing $440 +(not many takers)

We did the dance, after a while, we settled at $240.00 and he threw in a couple of boxes of cheap, import, range food. (Seemed about right for a used one)

Just more proof to the adage: All things come to he who waits. (as long as he's bustin' his azz while he waits)

Yep, the trigger and spring kit I ordered is Mcarbo, they have a bunch of interesting stuff. (patience grasshopper) I have a couple of used holo sights in the possibles box, just have to fabricobble up a QD mount. Around here, that Sig is kinda pricy, I'll likely start with a used Pro-Point. (big and klunky looking, but should work well to start)

I walked 2 shows today and couldn't find a usable muzzle brake in 9mm.

I guess I will end up drilling out one of my .22 caliber brakes or carving out one in the shop. Da Bay might be worth a look later tonight.

Keep them cards and letters coming, boys and girls...

I went full tilt on the 40 S&W Sub 2k that I bought a while back. I think I bought almost every MCARBO part they offered. I really like the trigger now - 4.5 lbs. The swing away optics mount from them is a must have,IMO.
Look on Amazon,you can get the Romeo 5 red dot for around $120.

This is a really fun little carbine to shoot,and accurate as hell with the red dot. I shot 30 rds at 30 yards on a 3" shoot & see dot,all but 2 shots are on the target.

Did you buy the "two finger" bolt handle? Like it? Is the slip on foam tube pad taking the sting/face slap out of the buffer tube?

I could easily make both , but if the Mcarbo/factory ones work, for the money, I won't waste the shop time.

Have you shot the 9 mm? How does it compare to the .40 ?

Thanks for the input.

I put the "Recoiless" charging handle on mine,and Yes,the rubber bolt tube cover works well. I shoot LH,so I will need to make a shell deflector for mine,I have several burn marks on my right arm from the brass landing on my arm while shooting it.

I've never shot the 9mm version since I don't shoot 9mm.

I have a first gen Sub 2000 in 9 mm. It took Glock 17 mags and all I had were Glock 19 mags. A small saw and a little care got it to take my G 19 mags. Other then that I haven't changed a thing. It is a lot of fun to shoot, but I use the Glock 32 round mags most the time.

Like the OP, I got mine for a song, at a flea market, 2 extra mags and a hard case for $275. Get the neoprene tube that goes on the buffer tube to reduce the cheek slap. The Glock drum magazine doesn't work in them, so don't waste the money. I tried a QD red dot but it doesn't return to zero when you take it on and off, so I just use the irons. I have fun with it and it's a good stash gun.

I don't use the folding feature, other than for cleaning, so this is my setup.

I prefer linear comps on most guns, so it has a Kaw Valley version.

This red dot is an inexpensive import (I decided to try (vs the Bushnell TRS or Primary Arms model) based on a recommendation), but I have two and neither has failed to hold zero yet. The base came from Amazon, not QD, but again, not in MY way.

I used some peel & stick neoprene (made for Bow grips) on the stock tube, and added a machine screw sling stud to the butt and an Mlok adapter to the hand guard. Sling is an old USGI M1 Carbine model.

I mostly run it on Magpul 21 round mags, and they work fine. Good luck with yours, and have fun.

Make mine lean, mean, and 9x19!
