The answer could be a little more complicated ...
Magazines should exchange between the two makes of pistols, but if one had a particularly tight magazine well, or if a grip screw was a bit long, some binding could occur and cause someone to think there was a problem. With today's general lack of inspection and quality control almost anything might happen. However a competent pistolsmith could quickly fix any defect, and after that the various makes of magzines would interchange.
