    What thread should I get for .45 mac barrel?

    Looking at ordering a MAX-10/45 Mk2, and I realized I don't know what the most common thread pitch is for this caliber. I don't want the OEM thread pitch, but I'm not sure what to order it in.

    The internet says the most common .45 threads are .578x28 but the default Lage option is 7/8-9 (Looks like OEM), or upgrade to 5/8-24

    I assume I want 5/8-24, but is this really a common thread pitch?

    I have no plans to get a .45 suppressor, but we all know how this goes.

    Several of the .30 caliber barrels I have bought lately have been 5/8X24.

    With the exception of a 1911 all my .45cal pistols and rifles are 5/8-24. The 1911 is .578x28

    5/8x24 — and definitely suppress it.

    .578x28 is the most common .45 thread.
