Please talk me into, or out of, a 9" 300 Blackout...

Do it! Forget the SBR paperwork/hassle and get a Shockwave Brace (just follow the Empirical rules).
There's something comforting about having a short, easy wielding "pistol" with optic and flashlight that can put 30+ rounds into play if needed.
The brace helps with the control ability over just a standard tube and the 300 BO is a lot quieter than 223/5.56 in any bbl length.

Do you reload? .300 BLK ammo prices are a little silly. The cheapest .300 BLK is what, $.50/round? It only goes up from there.

5.56, 7.62x39, and 6.5 Grendel are available for half that.

Nah, I don't yet. And yeah, I know the cost of .300 Blackout is a good bit higher for comparable ammo in 5.56. The thing is, I'm not loading bulk FMJ into my AR mags either. At least not what I keep loaded and set aside for HD. So even if I was paying $1/round for .300 Blackout... I really wouldn't shoot the gun much. I'd buy it and shoot it a bit for S&Gs at first, but after a couple mags, I'd put it aside for HD, keep it loaded, and not touch it more than once or twice a year after that.

Practice? I'd just use my primary AR.

At any rate, I'm leaning pretty darn heavily toward Pass at this point.

All my stripped lowers started life with a pistol buffer tube, because once a rifle, always a rifle...

Only one still has a tube, and it's only job is to test new SBR uppers before the barrel gets engraved. I hate the handling of AR pistols if you can't shoulder them---and it makes you a felon if you do.

I do love 300 blackout, but I'm a reloader and I shoot cast bullets in mine almost exclusively. With a 10" barrel and an 8" silencer it makes a pretty easy to handle and shoot package.

I load and have been interested in the 300 Blackout for a new toy myself. That said I have a cheap Draco that takes care of the truck gun role and I don't have to load for it to shoot cheap. I do load some 7.62x39 but loaded ammo prices and availability say buy, not buy components. If you are a dedicated AR lover I suppose the entry level Draco wouldn't be in the running. For the money, truck,and home defense I felt like it was the most sensible one to aquire first. You do need to run ammo through your personal defense guns often, for your practice and to keep them loose and ready. My next acquisition is likely to be a 300 Blackout. Just because I want one, and I have the right to.
I hope that you and I will never need a truck gun,except for varmints and being prepared and carrying religiously is a waste of time and effort.
Who knows

Interesting timing. I just had a guy reach out to me about building him a 300blk pistol with the intent to hunt deer. I'm typically an opponent (experienced at least) of the 300blk for big game hunting, but his context does make sense - his state is shotgun only, which, for some reason, includes handguns... Even AR pistols.

So I'll be building an AR pistol in 300blk for him very soon, picked up the lower yesterday.

illinois has a handgun deer season but there is a limit on the case length of bottleneck cartridges.

Legal Firearms
...
Centerfire revolvers or centerfire single-shot handguns of .30 caliber or larger with a minimum barrel length of 4 inches.

Legal Ammunition
...
For handguns, a bottleneck centerfire cartridge of .30 caliber or larger with a case length not exceeding 1.4 inches, or a straight-walled centerfire cartridge of .30 caliber or larger, both of which must be available as a factory load with the published ballistic tables of the manufacturer showing a capability of at least 500 foot pounds of energy at the muzzle. There is no case length limit for straight-walled cartridges.

I wonder if the 1.4" case length dimension came about to accomodate 300blk handgun shooters.

The guy asking me to build it for him is not from Illinois.

Every one should have a .300 Black pistol

I recently built a 9.5" bbl 300 BO upper. Only shot 220 gr subsonics so far. Light recoil. Just loaded some 175 gr over H110 to test function. Next will be 100 gr supersonics. If all cycle smoothly without having to charge spring/buffer (I don't have an adjustable gas block), then I'll be happy.

I went with a 10" barrel, running suppressed and SBR'ed, all hoops jumped through and well worth it!
I just installed a Fostech Echo trigger in it just for giggles, can't wait to get some range time!

I've never used my 8" suppressed SBR in 300 blk in an HD application where others wouldn"t have worked just as good or better buuuut don't let that stop you.
