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

Rookie question here:

I started poking around and looking into PCC's after seeing the SIG MPX and found the more affordable Angstadt udp-9. Cool looking gun, uses Glock 9mm mags, etc. but then I started thinking: what's the point of this style of firearm?

They throw the same ammo as a handgun, the barrel on this particular PCC is 6" so not a huge increase in muzzle velocity over a handgun.... why wouldn't someone just use a handgun?

Is it the accuracy gained from a full stock and forend that makes this platform preferable as a primary weapon? That's the only reason I can think of.

If it's accuracy from the full stock then whats the deal with the PCC's that have the buffer tube out the back but no stock on it? I see no practicality in that design...Plus it looks like barf.


Thoughts? Opinions?
 
Accuracy with a stock, specially for full auto select fire models.
The non stock ones are to get around silly rules south of the border where it's cheaper to buy a pistol then a short stocked carbine.
 
Pistol caliber carbine matches.
Because.

In the land of the free, AR pistols are a thing. Some guys don't use a stabilizing brace so you just see a receiver extension. This is not a concern for us here in Canada as restricted is restricted and we can put a stock on a pistol and SBR's aren't a thing here.

You know, you don't have to justify it if you want one.
 
Non-restricted, fun, ten round mags, can shoot in the back 40, cheap to shoot, some indoor ranges don’t allow rifle calibers, easy to transport to an official range ( same caliber for many different firearms and can share magazines with many different firearms), and they’re small, light, and handy.
 
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
 
Personally I like it because I like limiting the amount of calibres I have.

For example, I reload 9mm and 44mag for my handguns in each, so I also have a Beretta CX4 Storm carbine and I bounce between different Ruger 44 Carbines.

They are great to shoot, too, and generally much easier to shoot than centrefire rifle calibres.

No I wouldn't shoot a deer with a 9mm rifle, but it's a great soft-shooting intermediate round for range fun.

When I bring new shooters to the range I start them on 22s and the next gun is always the 9mm rifle.
 
I bought mine for fun. I have a just right carbine in 9mm. I use it for hunting coyote and wolf as well as small game and protection in the bush should I ever need it. It's non restricted. I can take it just about anywhere. It's cheap to shoot. Bulk ammo is easy to get. Ammo is light. It takes 10 rnd mags. Most ranges allow them to be used on indoor ranges. The longer barrel gets me enough velocity to cleanly take the game I pursue with it. It's an accurate platform. Next to no recoil. Adjustable for new or young shooters. Can add on a lot of accessories if that is your thing.
When ever someone shoots it they smile. If a black semi auto can change the views of non shooters with a positive reaction that's one less vote against our community
To some all that up....its fun and I enjoy it
 
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.
 
Because the look you get from some people when out in the wilderness with your non-restricted "SMG" is priceless. It's also very cheap to shoot (9mm) and shares ammo with other guns.

The real question is: would we still own PCC's if AR's were NR?

Click to expand...

Why wouldn’t we? PCCs (in 9mm at least) are still cheaper to run than .223. And, AR based PCCs have several distinct disadvantages compared to purpose built SMG/PCCs.
 
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.)
 
OP it all depends on the gun.

Some are NR, so you can use them outside the range.(can't w/handgun)

9mm is cheaper than 223, so it's cheaper practice if it's a AR platform.

Accuracy with a full stock is greatly improved.

The ones you see without stocks are legally pistols. In the USA, you can own any pistol but a rifle with a barrel under 16" is a sbr, and you have to pay the government $200 for a tax stamp and go through additional background check/wait a while for the paperwork or whatever. Some people won't get an sbr for Big Brother fear of the state reasons. None of this matters in Canada though.
 
One of the fastest growing sports down south, the USPSA PCC matches. I'm just waiting for them to catch on here in Canuckland.

Too bad we can't have 40 round mags here though.
 
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
