The G29 is a 10mm, G30 is .45 or 11.3mm

I don't think they will work

Yes, they will fit in the gun...Why would you want to do that? The feed lips probably won't allow the .45 cases to feed properly (I've never tried it, but you're .05" shy, buddy). They may hold the .45 too low to be picked up.

Definitely don't plan on it, just curious because the 29 mags actually seem to fit more flush with less bulk. I didn't mean to infer I was going to do it. In a side by side comparison they look identical. Of course that doesn't mean they are.

Naw, they're really not. Compare the width of the magazine feed lips. I think you'll find that the 10mm is 1/20th of an inch narrower. Otherwise, the tube and liner are probably identical, but that little bitty change will keep your .45 ammo sitting lower in the tube and keep it from exiting the mag just a bit longer.

Mags are interchangeable between the 29 and 30. You can also take the barrel off of a G36 or G30 and place them on the 29 frame. Sounds crazy but works flawlessly, functions perfectly and has no evidence of abnormal wear.
