    In another thread, someone mentioned they carry hot 45 Super ammo in their Glock 21. Is that safe to do? Are there any potential problems with the unsupported chamber area? If it's safe, does the G21 need beefed up recoil springs or other modifications?

    Thanks.

    I have done it with a 6" KKM barrel and 21# (?) spring a few years back. My 21still runs fine. I have also done it with the KKM in my 20.4 ounces long slide.
