Mr Concours- Heh heh, well, I know more about *these* products than I do about all the detailing products out there these days
The MP38/40/41(now there's a rare one for you) all took the standard 9mm, but function best with the hot "machine pistol" load.
I just realized that in a few cases I typed "7.
62" for the WWII German round instead of "7.
92
Off to edit....
