Mec-Gar Magazines Falling out of Swiss Model 1929 and Mauser Parabellum Model 29/70

I originally posted this topic on the “other” Luger forum. But I think the ultimate Luger magazine guru, G.T., hangs out on this forum? Would be great to hear his opinion. My curiosity is killing me!

I’ve found contemporary Meg-Gar magazines will intermittently drop out of my recently-purchased Swiss Model 1929 Luger during live fire. Furthermore, I can jiggle a contemporary Mec-Gar magazine out of the model 1929 by hand with the toggle locked back, as shown on this video:

(Those are dummy rounds. The magazine is easier to jiggle out with rounds in the mag, but the mag can be jiggled out when completely unloaded).

But I cannot jiggle the OEM Swiss magazine out of the pistol, as demonstrated on this video (and it does not drop out during live fire):

I’ve also experienced at least one of my four contemporary Mec-Gar magazines dropping out of my 29/70 during live fire. But I cannot jiggle a Mec-Gar magazine out of the 29/70 by hand, like I can for the Model 1929.

I think the issue is the cutout for the magazine catch, upper left corner. See attached image. The upper left corner cutout is (near) square for the contemporary Mec-Gar; radiused for the Swiss Model 1929 and Mauser Original 29/70 magazines.

Otherwise, I’ve had great luck with Mec-Gar magazines in my 1906 AE (7.65 mm), MM2 (7.65 mm), and 1939 Mauser (9 mm).

I did find this old thread, so I’m not the first person who has experienced this issue:

P.S. All of my “contemporary” Meg-Gar magazines are post-2018, which is when I purchased my first Luger.
