Pistol Calibre Carbines: Why? What's their benefit?

Definitely fun!

They're great for plinking and cheap enough to shoot that you can plink a lot. :)

I have a Beretta Cx4 with over 4500 rounds through it. Been experimenting with reloads to try for accuracy (I know, I know, the 9mm has the ballistic coefficient of a brick thrown sideways, that's the challenge!). After researching a bit, I made reloads using IMI brass, WSPM primers, 5.9gr of Hodgdon CFE Pistol and Hornady 110gr XTP .38 (357") bullets. It shoots 9 rounds of 10 under 3 MOA at 100m from the bench. :d

Now that is not too shabby ...maybe have another look

Thureon Defense here;

-Same ergos and controls of an AR15/M4
-AR15/M4 furniture compatible
-9mm reloads are $0.18 each
-9mm has less recoil so faster follow up and moving, easier on the shoulder for long day training or smaller bodies.
-All Glock 9mm mags work, even the G26 minimag
-Non-restricted back yard fun

Definitely one of my favorite guns.

X2 only mine is a 40 cal. Also one of my favorites. Sold my JR Carbine and my Beretta CX4. The Thureon Defense is definitely a keeper.
 
Less noise
Less expensive to shoot
Can be used where rifle caliber is not allowed or not desirable. (Indoor ranges)
Often very simple with no gas system or locking bolt
Convenient if you have a pistol and a carbine that takes the same ammunition. Even better if it takes same magazines.
 
The ones that take pistol mags are fun enough. Plinking and camp fun gun. Unfortunately, as ###y as they look, the MPX and Scorpion are hard for me to pull the trigger on due to the dumb 5 rd mag limit. Expensive, 5 rd limit and restricted just doesn’t cut it for me.
 
In the really long run I guess cost, 9mm is on average cheaper than 556. Although recently we have seen some epic deals on 556.
Also for what it's worth it's quieter indoors.
In some cases you can rock the same mags as your handgun for your sub. Which could simplify logistics for stuff like 3 gun comps.
Some are non restricted.
And said non res subs are cheaper than non res carbines.
Lighter.
For the actual operators that get full naughty, it's easier to control in full auto.

And sometimes it's simply the fun factor.
 
My JR and my AR are set up almost identical.
Yes, some of the manual of arms is different...but when pulling the trigger they "feel" the same.
This means practice for far less than 1/2 the cost and a fun carbine I can take anywhere.
 
The ones I have shot were fun.
Most indoor ranges won't let you shoot a regular AR so a PCC is a good way to practice your rifle technique inside in the winter. For competitive shooting, IDPA has a Pistol calibre carbine division.
I do find that follow up shots are slow compared to an AR. I have been told it's possibly because of the blowback gas system and the ammo doesn't have enough gas to properly drive a regular compensator.

Also worth noting;

Most of the SWAT Teams in Europe use PCCs to storm a building. Usually MP5 rifles in 9mm.

I think it has a lot to do with minimizing potential collateral damage if there's a shootout.

A 9mm bullet that misses a bad-guy will not travel nearly as far as a .223 round will.
(Nor will it penetrate as many walls.)

It would seem so...but no. Check out the ballistics of the SBRs. In particular a 5.56 mm or .223 55 gr HP has a lot less penetration through walls than the pistol rounds. It falls apart.
Many teams have ditched their MP5s for SBRs.

I thought about 9mm carbines it seemed a convenient round to use but everyone that had one complained about accuracy and reliability of the rifles so gave the idea up

You've been misinformed. Mine have been very reliable and more than reasonably accurate out to 150m.

PCCs are great fun. Cheap to shoot, little recoil, 10rd mags and lots available in NR.

As far as reliability goes, in all I've had two failures to eject due to defective (low charge) commercial ammo where the case didn't have time to fully clear the ejection port before the breech came back forward and jammed it against the forward edge of the port, that's it.

Be aware there's one issue with the Cx4: because of the way the trigger group works, out of the box it has a very heavy trigger pull (guesstimate 10 pounds or more) There's a DIY fix for that, that brings it to a more reasonable level (maybe 5-6 pounds), and there's one US maker of replacement trigger parts that addresses that issue also though I'm not sure he ships to Canada.
 
I've owned the Kel-Tek Sub2000, an HK USC, a couple Kriss Vector (gen 1) and a 9mm AR-15 and while they are fun and cheaper to shoot I've found that the novelty wears off and they get boring.
As a non restricted I find them to be useless since they don't pack the punch to do anything like hunting, I have other non restricted semi's that are more accurate and since I reload the cost savings isn't enough to worry about too much.
I've kept my 9mm AR because out of all of them I get the biggest smile from it and if I ever decide to 3-gun or if PCC matches catch on up here I'm covered.
They're accurate enough for under 100 yards and they are fun but I just seem to get bored with them and sell them to buy something else.

Az.tech armory is the canadian dealer for those cx4 upgrade parts. Sierra papa is the company that makes them in the US.
