    What do you think of this 400 Corbon caliber?
    Have you ever converted a Glock 21 before?
    It's supposed to be just a barrel swap. No need to replace RSA or any other part.


    I know we can do whatever we need to do with either 45 ACP or 10mm but it's not a "need" thing but in the "cool/want/awesome" wishlist :D

    I think it would be very cool even if ammo cost is quite crazy.

    Do you have one? pics?

    I'm a 357sig believer so I guess that necked down design caught my attention. :rolleyes:

    Even if you reload, you have to buy a die set for that, and brass is way not cheap either.

    Yep. It would be an amazing challenge.

    I guess that’s the attraction, something different.

    I understand that you can turn the brass .45 acp into .400 Corbon,
    in theory.
    I have done it with some of .40sw to .357sig, since here they are impossible to obtain, they have worked without problems, I used them twice and threw them away.
