I know 10mm is the best mm, in a handgun... but what's the use case for a 10mm PCC?

For 9mm PCCs, I've seen the utility/advantages/cost savings/etc of those... but 10mm I don't get at all other than the entertainment value. Is that the big draw, or am I missing something?

Are you looking for an excuse to buy one? You don’t need an excuse to buy a gun! Just go for it.

Nope, I have no interest, but I'm curious. I don't like not understanding things.

So far, I see:

more power than 9mm, but more expensive
not a bottle neck cartridge
less power than a 556, but more expensive

Not sure why that's a win, other than some esoteric hunting rules maybe about bottle neck cartridges (which is why that 350 legend thing exists, so it is an actual reason in some places)
 
Just cause is about my answer for just about everything I’ve got (not just gun related)! 10mm in an AR style is a hoot and you could use it for hunting (pigs come to mind). Also, Kriss (makers of the Vector) makes glock mag extensions made for 10mm (no more modding the 45 cal extensions) that will get you 33 rounds of sweet 10mm goodness! :eek: Get some!!! ;)




You should hear cash register rings and not gun shots when shooting 33 rounds of anything these days!!!

Do you have a 10 mm handgun? If you do a 10 mm carbine that uses the same magazines makes perfect sense. I have a Glock 20 that I keep in my RV for wild animals and people. I think a pistol type carbine that took the same magazines would be awesome. 10 mm as posted above gains a good amount of velocity and becomes quite powerful out of a longer barrel. Myself I just went with the flux brace and use my pistol as an almost PCC

Ahh... Well, I am with you on that. I see no point in a 9mm AR, much less 10mm. 5.56, 300BLK, and 6.5 Grendel (or 224 Valkyrie if you prefer) cover every eventuality I can think of, in rifle or pistol format, and none are expensive to shoot my own reloads. In fact 5.56 is only interesting because it is everywhere. 300BLK and 6.5G actually cover all needs.

Not that a 500 Beowulf or 10mm or whatever wouldn’t be fun.

Does the Flux Brace work with the glock 20?
 
Others have covered it already but a semi auto carbine that shares mags with a handgun is a sweet system.

In 10mm you get the advantage of a cartridge that can use that extra barrel to build velocity and be more than just a handgun round.

I have a 9mm PCC and matching handgun but in some cases (147gr bullets) the carbine chronos slower than the handgun.

10mm, .357, .44 Mag, 45 Colt (loaded to its potential) do not suffer from such issues.
 
Now the other question is, since I shoot lefty, will it be be "ergonomic" for me? Ive got some other iron in the fire at the moment, but I think this is something I dare say I may need...

Why? What makes it the best mm in a handgun? Power, right? What's its disadvantage? Control-ability. That's why the .40 was created. Why do people get 9mm PCC's ? It increases control-ability and accuracy. So, the same and more so for the 10mm. Power in a 9mm PCC doesn't increase that much, but, as mentioned, in a 10mm it does. The PCC's extend the capability of the pistol cartridges and significantly more so in 10mm.

That's how I see it anyway.
 
PICS!!!!! never knew this even existed

The FBI used to shoot their MP5 10mm guns at the range I belonged to. The guy who ran that side of the range scooped up the brass and gave it to me. Even though the fired cases had flute marks on them they reloaded just fine. Still have a bunch of those cases.

I did a 9mm carbine mostly because I wanted to. The reason I tell myself I did it is to be able to shoot an AR and not spend so much money on ammo. Turns out that doesn't work out. When I think the ammo is "cheap" I shoot twice as much and it's a wash. But whatever.
 
9mm PCC: cheap to load for and good for many things.
10mm PCC: ????????5.56????????
 
10mm is probably less than 5cents per round more to load for then 9mm. If reusing brass and lead bullets.

It has bigger oomph and cool factor over 9. 😉😁
 
9mm is the equivalent of a rimfire conversion kit in a 556. Practice with it then bump up to 10mm for operating. 😁

But we all know the real reason for this thread...does Wolff make steel case 10mm?
If so, will it wear out my gun?

If reusing brass and bullets, I bet 30-30 is about 5 cents more per round than 9mm. Lol.
.44 mag, .50 AE, etc etc.

It will wear out a grock in precisely 56,345 rounds.

Not sure. PCC's are FUN, but as far a defense, I don't see any scenario why I'd want a pistol caliber over a rifle caliber for that purpose.

If you're not talking defense, then it's like anything else; why a .22 mag carbine or a 5.7mm over a .22 carbine? Why a 10? - just 'cause we like them and already have the others!

Well for me I like the 5.7 for the ps-90. It’s a blast to shoot and has great cool factor.
 
I do. Indoor home defense. Way less chance of permanent hearing damage.
Lol, I had a feeling someone would say that.

So, you're in a home defense situation where you have to shoot someone with your carbine - and you'd rather have a pistol caliber than a rifle caliber, because of future hearing issues?
OK...to each his own. But I've been around many shots fired without hearing protection - my ears are OK - except when my wife nags, then I can't hear S#$T.

I'd rather use a sbr/braced pistol than a full sized long gun inside my house for what should be obvious reasons. Light off a 5.56 SBR/pistol in a hallway and you might have a different perspective.

The old argument of "well if I'm going to use a long gun" makes no sense in this context. A pistol caliber sbr/braced gun is no more trouble to pick up by your bed than a pistol and is undoubtedly an upgrade over a pistol.

I could say well if I'm going to use a long gun why would I want 5.56 when it could be 7.62? 10MM out of a PCC will put a hurting on anyone. I have traditional ARs, but my bedside gun is a braced 10" 9mm and I do not feel undergunned.

We were talking about the OP - a 10mm PCC. Personally, inside my house I rather a handgun than a shoulder-fired weapon - but that's a different thread.

But, if I'm going to use a carbine for defense - I will chose the rifle caliber every single time, which is what I posted. If YOU choose something different - more power to you.
 
Will a blowback 10mm PCC cycle 40 S&W without issue? If so, then that's a bonus if you own .40 firearms.

38/357 ish situation.

Btw, that FLUX brace is an effing alphabet honeypot!!! The spare mag holder is everything a forward vertical grip wants to be.

This is just food for thought, and I realize we are getting way off track of the OP but I wouldn’t base my decision of what to use for HD on what’s going to cause the least hearing damage. That is beyond silly IMHO. Guns are loud, especially indoors…all of them will give you some degree of hearing damage, but if you are in a situation where you are firing a gun off in your house at someone, trust me, that is going to be the last thing you could possibly care about. And also trust me on this, you won’t even hear the shots.

A more important factor to consider when selecting a HD weapon IMO is penetration. Believe it or not, the fact is, 5.56 penetrates walls and other obstacles in a home a lot less than 9mm (or any other pistol cal.) does.

All this was to say, choose your weapon based on what fits your particular situation and needs. Whether that be a pistol/SBR/PCC/Shotgun/rifle, whatever it is “Hearing loss” should not even be on the criteria list. This is coming from someone who has had a pretty substantial hearing threshold shift since my initial baseline as a direct result of shooting indoors….a lot. But believe me, in the situations I was shooting indoors at lease….I would not have chosen a PCC given the choice.
