Roger that,
My 1937 S/42 / VoPo shooter has performed flawlessly for several years now. Fresh springs, MecGar magazines, S&B 124gr 9x19 and no noticable problems whatsoever.
I recently got a batch of Winchester White Box 9mm and although it is good, the S/42 doesn't like it as much as the S&B. Let's say a 90% reliability score with Win, and a 99.9% reliability score with S&B.
(ah, and never load the mags to the max. 5 - 6 rounds always works well).
British car electronics are like Russian quality control, German humour and Dutch generosity: Not good
