So I’m looking to set up an AR9 pistol for home defense. My budget is around $1200 all-in (Gun, Optic, accessories, etc). Problem is, I don’t know a lot about the available options for AR9s. Can anyone either suggest a decent pre-built or build options?

Why restrict yourself to AR-9?
Mag-in-grip carbines like the Linda or a Mech-tech conversion have a couple advantages:
>More compact for a given barrel length.
The AR-9 is almost an inch shorter than an AR-15 at the same barrel length (because no barrel extension/locking lugs), but still costs you about 4" vs. a mag-in-grip design. In fact, a 16"-barreled mag-in-grip with no flashhider is the same or handier than that 10.5"+flashhider in your picture.
>Greater mass in a shorter bolt.
Because the bolt doesn't have to fit into an AR-15 buffer tube, you get more mass per inch of length. More total mass means more gentle recoil, which in turn means faster follow-up shots; less inches of bolt length (especially in combination with telescoped bolt) means you don't need as much receiver/buffer tube behind the magazine as ARs do.
The AR-9's only real benefit, to my mind, is the availability of good aftermarket triggers. But this is more a matter of comfort than practicality, in terms of home defense. Even a stock Glock trigger isn't going to keep you from making good hits under 25 yards, and hammer-fired guns like the Linda carbine will be even less bad.
(The 1911 mech-techs are the exception here, as they obviously inherit the trigger pull of the 1911 frame, which can be anything up to racegun-level, but if I have to choose between "single-stack" and "mediocre striker-pistol trigger pull"...)

>AR9

>Not AR15 5.56
Why? 5.56 overpenetrates less than 9mm and removes intruders better.
Jordan Watson
I almost made the same mistake, just get an AR pistol in 556, and whatever 9mm wonder you want.
Kevin Hughes
Reduced recoil, faster follow-ups, cheaper ammo when I take it to the range, not gonna permanently damage my hearing, etc. Even if it penetrates, its much less likely to kill someone.
I already own an AR-15 btw.
Gavin Jackson
Kind of cool, but I want the familiar ergos and aftermarket of the AR platform. Besides, Sub-2ks exist if you want a cheap 9mm carbine
Connor Edwards
9mm ARs have noticeably more recoil than 5.56 because they are blowback. An over penetrated 9mm carries more energy and maintains its trajectory better than proper HD 5.56 because it’s slower and weighs more.
Noguns retard detected.
Supersonic 110/125 grain 300 memeout is the best HD round. 5.56 second best. Then #1 buck a distant third (00 is for retards). A pistol caliber is a comprise only to be used when required, meaning you need one hand for the gun and one hand to drag kids or something. Not understanding ballistics is not a reason to make that compromise.

Which trigger connector do you have in your glock? With my mechtech ccu on, the trigger is obscenely heavy (heavier than my trigger scale can measure)

Sub-2ks are flimsy trash, though. (Unless you really do care about the folding gimmick -- then they're flimsy gold, I guess?) Whereas Mech-techs are actually quite solid mechanically, and I expect Lindas as well. I'd definitely advise anyone considering a Sub-2k for any reason other than "I really, really want it to fold in half" to go with whatever other alternative, from Hi-point to AR-9, seems most attractive.
Also, Mech-techs aren't cheap -- sure, "only" $500ish for the bare conversion kit, but by the time you add a $300 used glock (or $150 p80 frame and $50 parts kit), a $100 optic, and some mags, you're up in the same price range as AR-9, Scorpion EVO, Linda, etc.. It's only cheap if you're already invested in Glocks to the point of having spare frames and mags lying around unused. I got a Mech-tech because it's the PCC I wanted, not because cheap.
Currently using a Ghost Minus connector and stock trigger spring, but I've tried several options with no unexpected differences.
How many times have you (dry-)fired it? The front surface of my mech-tech's sear hook was kinda rough; trigger pull was just comically heavy and gritty. (FWIW, then using the same "-" connector with a NY1 gray spring.)
I noticed a real improvement within 10 cycles of dry-fire, then ran ~100 cycles of dry-fire which really smoothed it out. Then after maybe 100 rounds of testing/plinking, I swapped back and forth between the slide and carbine upper a few times, and at that point I couldn't tell any difference in trigger pull. (Not to say there was no difference one might have distinguished with a trigger scale -- I don't have one.)
Correct, those are not my pics, but as I said I have a Mech-tech, and indicated I'm satisfied with it as having a "stock Glock trigger" and "mediocre striker-pistol trigger", it's quite reasonable for user to ask me questions if his Glock/Mech-tech's trigger pull seems different than stock and much worse than mediocre.
Julian Hill
Of course, the ergos and aftermarket are valid reasons to go with AR-9, and I'm no longer trying to talk you out of it, as long as you've considered all your options.
I should've acknowledged that before nitpicking about the Sub-2k; apologies.
Gavin Garcia
A 9mm AR has more recoil due to direct blowback, .223 is just as cheap, or cheaper than 9mm for range fun, yes 9mm will be quieter, but I'd be more concerned with incapacitating the intruder.

one reason to use this over a 12 gauge shotgun?
Isaac Evans
it doesnt have lower recoil, and it will damage your hearing
Noah Cook
Thanks for the input. I'm sure I've dry fired it about 100 times over the years, but it's been so long since I've picked it up that I dont remember. The glock has a ghost 3.5 connector (I think it was the only one of that description available at the time.)
The ccu would be awesome if the trigger functioned well, and even as it is, I have had very impressive results in terms of precision at 100yd.
I'll take a look at the sear hook, and make it a point to wear it down some!
Zachary Robinson
Looks like shit

If you have an existing AR pistol consider a Stern Defense Mag block and then you have 1K to spend just for the upper/buffer.
Saves you a lot of pain OP
David Howard
Get a PC9

Hudson Jenkins
If you want to use a 5.56 lower, I'd consider endomags over a mag block.
To be sure, it's economically a wash, or even a win for mag blocks if you want lots of 9mm mags -- $180 for a mag block, plus $20 each for glockazines, vs. $13+$27=$40 each for pmag+endomag. So break even looks like about 9 mags. (More if you go for 33-round glockazines to match the endomags' 29-round capacity)
But IMO, even if it costs a little more, it's worth it to have normal mag change ergos, and visible capacity with window pmags is certainly a nice bonus. (You'll need to add a paint spot on the endomag spring to make the window function right, but that shouldn't be hard.) Especially considering OP mentioned standard AR-15 ergos as a reason to go with AR-9 over other platforms, I doubt he wants to learn that weird finger-stab mag release.

Are you some fucking retard that plays too much counterstrike or something? ar pistols do literally nothing well. Its a fucking rifle round and the AR receiver makes or a poor pistol in every way. Just fuck off back to video games.
Samuel Bell
Wow, the confidence at which you spew utter nonsense is breathtaking. 9mm decelerates MUCH quicker than 223 and consequently doesn't overpenetrate. Both the shape and the velocity of 223 means that the bullet will pass straight through your attacker with minimal cavitation
Kayden Gonzalez
PCCs are the worst choice possible for home defense. There, I saved you 1,200 dollars (which isn't enough, incidentally).
Logan Watson
>ar pistols do nothing well
Not true. It's important to match the gun to the game, and AR pistols are exactly the right size for woodchucks.
Ethan Bailey
>worst choice possible
I'm pretty sure a single-shot .22 LR with busted sights is actually worse, so no, you're full of it.
I'd definitely agree PCCs are a sub-optimal choice for home defense, unless you basically rig the evaluation by assigning a particularly heavy weighting to noise level. And while that's not entirely unreasonable if you have kids in the house ("Sorry you have to go through life with hearing damage, little Sally, but Daddy was too busy counting layers of drywall to think about your ears"), I get the impression it's more usually adopted by people who like PCCs, so they can justify PCCs as "optimal".
But here's the thing -- while PCCs are generally sub-optimal, they're also perfectly adequate.
There's a continuum of firearms choices for home defense, and even ignoring comically overpowered options like nuggets and 20mm cannon, it spans the range from single-shot .22s through some random carry revolver or pistol, some unadorned service revolver or autopistol, up to the modern choice between tricked-out full-size pistols (at least a light -- full Roland Special, or long-slide, etc. builds optional to user's taste), 18" shotguns with lights, 5.56 carbines with lights and optics, and PCCs with lights and optics. (The latter two, of course, include braced "pistols" as the carbines they're actually used as.)
And the thing to realize is, each of those modern choices, for people who practice even a little with it, is much more like the others in effectiveness than like the "old" choices.
The optimum is probably 5.56 or 12-ga (maybe the pistol, in an old house with really narrow hallways), but you're not giving up much at all by going with a properly set up pistol or PCC; it's still incomparably better than an old .357 or hi-power with no light.

But if he has decided on 9mm for whatever reason he should just get a handgun. Unless he is living in a mansion or a field its much less obtrusive
