    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?

    the ballistics of the cartridge take more advantage of the increased barrel length.

    end up with an all around weapon that could do home defense and game up to deer sized that is fun to shoot.

    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.

    Why have a 38/357 or 45/44 lever action?

    This.

    The 10mm is basically semi auto friendly 357. So imo a 10mm PCC is the modern version of a lever in 357 as a mate for your pistol.

    MP5/10mm is a freaking hammer, hunted hogs with it and might deer hunt with it this season.

    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.

    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.

    Some people like captain crunch, others like cinnamon toast crunch.
