The entire issue of the May/June 1979 American Handgunner magazine
is re-printed here, one scanned page at a time.
Note that Winter's SWAT pistol was to use a special new cartridge, .408 bullet diameter, similar in size and shape to the 41 Remington Magnum, but not at all interchangeable with that round.
The new .408 cartridge would be restricted for law-enforcement only and it would come with very special ammunition designed for urban combat.
