No real advantage over a basic 5.56mm AR SBR, takedown and conceal ability are about the same. Reloading components are easier to find in a 5.56mm also.

60 grs, 3000 fps, 10mm carbine
Another example of a pistol-caliber carbine that soft armor WON'T stop...

OMG, I just LOL'ed...

Garand (anyone on the planet, for that matter) pointing out to John Davis how an AR shorty is a better option than the carbine JD posted about...

Both of you are actually correct imo. The AR is the better option, but the story demonstrates how close the gap can be with other guns.

it aint close at all, 10mm and 223.. This special ammo costs 3x what 223 sp's cost, it won't have 1/2 the effective range, either. It has no 22 unit, cant use our GI rd or mags. I haven't looked at the price, but I bet it's lot more than the $600 that gets you a fine AR in 223, regular 10mm loads will have about 50% more recoil, too. So, other than having some power with subsonic ammo, it's a loser.

Read what I said! It has NO advantage over the AR

Be better served by an AR57 stoked with properly "repackaged" 28 grain SS198LF running 3,200 fps.

This load from this gun WILL punch a hole clean through TL3A - TWICE, plus the body inside it.

"Handgun-caliber carbines" is of my favorite soapbox topics. Won't repost every blathering thing I've said previously, but some highlights -

Old Marlin Camp-9 gets over 1600fps with 115-grainers from corbon and federal's 9bple. It (yes, really) averages 1825 fps with 100-grain corbon pow'rball stuff; 740 ft/lbs from a 'mere' 9mm carbine.

Tiny 16" 1892 in .357 magnum runs more than 2,000fps with 125's, and right at 2,000 with 140's. Basically the same muzzle energy as full M193 from a 20" gun; from a "handgun" cartridge in a rifle smaller than a 10-22 rimfire.

My favorite example; a plain-jane looking 20" levergun. In .454Casull... For muzzle energy, it rules the roost by a huge margin. It runs between 2750-2850 ft/lbs with most factory loads, and more than 3,000 with some. (It really likes the 260-grain winchester partition, running it at ~2410 fps, about 3100 ft/lbs. Up there in .30-06 and even .300 Win Mag territory, from a normal-looking 20" lever action.

Truth be told the 10mm is a seriously potent round in longer barrels. Being a pistol bullet it can never compete with rifle bullet ballistic coefficients, but it CAN deliver some impressive ballistics out beyond 100 meters.

When it comes to armor penetration the 10mm suffers the same negatives as do all other large-diameter pistol calibers.
