First post so thanks to all that make this place happen.
I have a glock 40 mos and a 19. I would like to add a pistol caliber carbine. Idk if i should go 9mm or 10mm.

I like my 9mm. Cheaper to make go bang than 10mm and unless you're hunting with it, doesn't seem to be much advantage to that one more millimeter. Also, since your handgun is a Glock that seems to be a go to maker of magazines for the manufacturers of PCC's.

Looking to get a jrc or if i found a used kriss vector for a good deal that may be a option or pray and wait for a pc carbine in 10mm.
The main interest in 10mm is the range and power i have had with the mos with a red dot. And weather you agree if its not safe or whatever its a fact. glock 10mms can shoot 40 s&w all day long with no issues. Ive probably but as much 40 through my 10mm as 10mm. So that gives me another caliber option.
But 9mm is lighter and cheaper. Thanks to all
For simply range use I don't fire my magnums much. Mostly I'm shooting my 9mm PCC or my double deuces. Cheaper ammo and makes holes in paper equally well.
 
If Ruger offered its PCC in 10mm I'd consider it if that much power is desired. We love our PCC in 9mm....VERY rugged and beefy for its compact size. Uses Glock or Ruger mags. Not as compact as the Keltec sub 2000 but super easy to manage. I've bought Rem ammo for <8 bucks a box on sale at Walmart many times. You can't beat that easily.
 
Yeah pc carbine is looking like its gonna be the pick. But one dark horse came up. I found ak-47 style 9mm shooting glock mags at Atlantic firearms but i dont think it’s a actual ak piston driven etc.

i saw the take down pc this last weekend. I carry a 10/22 everywhere i go at the moment. And thats the gun i grew up with so i like the pc feel. Gonna find one with rails I think.
 
Currently have both Ruger PC Carbine & Kel-Tec Sub2K, both in 9mm. Have previously had JR Carbine, and Marlin Camp Carbine, also both in 9mm. In addition to those I've had 2 Ruger .44; Carbines and several .357 & .44 lever action Carbines.
No question about it, the Ruger PC Carbine & Ruger .44 Carbine are the best ones I've ever had. Really wish I'd held onto one of the .44s. I've had the opportunity to handle and shoot the Kriss in .45. great gun but not worth the price. I'd have to get one at a big discount to consider one.
10mm would be a great caliber for a carbine, but until Ruger makes one, or a discount on a Kriss comes up, I'd stick with the PC Carbine 9mm.
 
With the 2 choices I would get the 9mm. A lot of ammo choices and the price is reasonable. It is also cheap to reload.

The 10mm is a good round, but it isn't the power house some make it out to be. 44 magnum beats is easily. There are factory loads that are pretty good. I like the Sig Elite performance. It is right at the 1250 advertised speed.

Most of the factory loads, otherwise, are right at 40 ballistics.

Now handloads can pump up the numbers and save a few dollars.

I am not sure what your specific use it is intended for. I would rather have a 44 Magnum revolver and lever gun before a 10mm or 9mm
 
I own one of the Ruger PCC 9`s. I would buy it again. I`v had not trouble with it or the Glock magazines I use.
 
9mm.

Inexpensive ammo, good parts and mags support and the bugs have all been worked out.

With 10mm while it’s a little better ballistically you don’t have any of that, you have to add significant costs to make sure it runs, more costs for accessories and more costs every time the UPS man arrives. Forget all that.
 
Bought one of the new 9mm Ruger carbines ---liked it so much I bought a second one

Have a G20 but finding a compatible carbine is pretty iffy these days----it would be cool to have one but not worth the hassle or wait.
 
To the OP: 9mm no question.

I have a PC9. Fun little bugger,,, a ~Big Boys 22~ if you will.
Not so sure about any 10mm versions soon, but it appears a 40 cal is headed our way:

U.S.A.-(Ammoland.com)- Sturm, Ruger & Company, Inc. (NYSE: RGR) is excited to introduce six new PC Carbine configurations including three free-float handguard models chambered in the popular 9mm Luger and three standard models offered in the highly anticipated .40 S&W chambering. These new PC Carbine models are offered in varying magazine capacity and threaded barrel configurations to ensure multi-state availability.

With improved utility for home defense and competition, the 9mm free-float handguard models feature a hard-coat anodized aluminum handguard with Magpul M-LOK accessory attachment slots on all four sides for easy mounting of M-LOK-compatible accessories. The appeal of the popular PC Carbine is further broadened with new models designed to accept the powerful .40 S&W cartridge.

They lost me at '.40 S & W',,,,,,,

Just not a 40 guy I guess.

All the PCs have at least a top rail and fore-end light rail. Ruger has also come out with a free-floated shrouded barrel version that looks more SMG-like. We have about 600 rds through and haven't cleaned it or had a FTF from the Glock mags. On a side note....the stock rifle will bump fire so handily that 33 rd stick mags will just disappear with little practice. TONS of Fun for plinking, defense or pest control. In fairness, I have fed it only plain fmj ammo so far.
 
I have a few PCCs.

9mm - Kel Tec Sub 2000
357 - Marlin 1894CS
10mm - High Tower Armory/ Hi Point 1095TS
10mm - Mechtech 10mm on double stack 1911
460 Rowland - Mechtech on double stack 1911

The Marlin is my favorite; the Hi Point is the most interesting; The Kel Tec gets shot the most - cause it's just so much cheaper to play. I'd go 9mm first.
 
40 S&W in a carbine is a fantastic close quarters weapon. I have one for home defense paired with a 40 cal pistol. They share mags and ammo. More energy than a 9mm .

I can't disagree with any of that.

All true, AFAIK

Myself, I have nothing relative to 40 S&W.

Nothing chambered in .40,,, No Ammo, No Brass***, No Bullets, No Dies,,,, Nada.

(***Might have 2 or 3 pieces in my 'cull' bucket, only b/c the Wife or I picked 'em up at the Range by mistake.)

I freely admit to being biased and/or with prejudice towards 40,,,,,

Mainly b/c I reload.

380 cases mixed with my 9's,, 40's in my 45 ACP,,, As a result, I have an equal disdain for both 380 & 40 S&W.

As most don't reload, it's a moot point as far as their concerned.

And certainly not a big deal to me either. Simply a nuisance, but absolutely one less reason for me to bring thousands of 'em into my house, on purpose!!

LOL!!
 
The 10mm is a beast and would easily produce significantly more energy than a 9mm from a carbine (or anything other platform).

However, the 9mm is more than sufficient for most PCC roles. If I were wanting a camp carbine in bear country, I wouldn't hesitate opting a PCC in 10mm between the two.
If I were wanting something for around the home, I would (and have) choose something in 9mm.

My CX4 Storm loaded with Remington 124gr +P bonded Golden Sabers and topped with a red dot makes a handy dandy home defense carbine. This is my go-to if a bump-in-the-night leads to my GSD going berserk.

If I ever found myself needing more than 30 rounds of 9mm +P JHP from a carbine in this particular role, it's probably due to a rampaging demogorgon (and a flamethrower would be the only useful weapon upgrade).
^I concur with Snowdog with the 10MM suggestion, but i would go with what ever PCC and pistol combo that benefits ballistic wise in a longer carbine barrel, whether that is 357 mag levergun and 357 mag revolver or a 10MM semi-auto carbine and 10MM semi-auto pistol.
 
10mm would be the obvious choice for me, just not a lot of options for a pcc in 10mm.
I usually carry a g20 and would love a carbine with magazine compatability. I think there are 2 limiting factors,
#1 -cost, it will be pricey to feed at the range if you're not a loader , for some folks cost is no object but for most its the big one.
#2 -acceptable platform, you have to find one you like and the selection isnt great for a 10mm carbine.
In my opinion there couldnt be any other reason not to go 10mm, its a bonus that you've already got a pistol chambered for it.
Simple reason is that anything that any pistol caliber semi auto cartridge can do, the 10mm does better ( with the exception of some boutique non saami chamberings and obscure calibers. Oh, and 50ae - but i doubt youre finding a 50ae pcc, but it would be interesting)
Bigger, faster and heavier are all desireable features when comparing cartridges.
Best of luck on your search.
 
10mm - Hunting or need / want more power

9mm - everything else :D

I have 2 Glock 9mm pistols, a 19X and a 45.
I have a Ruger PC Carbine 9 mm.
Though I am limited to 10 round magazines I sure seem to go through ammo pretty quickly when I take my 9mm trio to the range. These guns are just plain fun to shoot. I burn through a lot of ammo, especially if I take my grandson along.:)
Contrary to what some believe a compensator on a 9mm does work and help recoil reduction. I installed an Odin Works “Atlas” 9mm compensator and it make a lot of difference.
But it does nothing for the titanium recoil block moving within the receiver so you do still have some recoil.
I plan to install a red dot sight on my PCC as well.

Whatever you choose, enjoy it. I do not own a 10mm anything but I am considering a Glock 20, among a dozen other wants. :D
 
As a reference point, I shot some 140 gr Underwood Extreme Penetrator 10mm Auto ammo past my radar. Out of a 5” barrel if was chugging along at 1500 FPS, just as advertised.

From my 16” KRISS 10mm carbine, I was hitting 1750 FPS. Considering the KRISS uses the same magazines as the G40 the OP has, the only deciding factor for me would be reloading. I load my own 10mm which makes it economical and versatile.

If I didn’t load, I would have gone with a 9mm a long time ago. I still plan to get a CZ Scorpion.
 
9mm

Capacity and cost are big pluses, and if I need more power than that in a carbine it would be a rifle cartridge 5.56, 7.62x39.
 
I want a cmmg banshee 10mm. But honestly like someone mentioned, the problem is functionality. Better off with a rifle round in just about any situation I can dream up

Unless you have a REALLY good reason for needing that extra punch from the 10mm [ bear / dangerous game ] ,I see the 9mm as a better choice.

If you see that the PCC will be your primary,and at any range under 100 yards your gtg,as well as the MUCH lighter ammunition AND lighter recoil.

I love the big boomers,BUT the reasons [ the key word = REASON ] to go with the 9mm are profound..

Perhaps I missed it later in the thread. I don't see anywhere where you mention what you want to do with these weapons. Hard to give intelligent advice without that info.
