Mag cross application

[Green Frog]

Well, I took the three mags from my 39-2 to the range today along with my newly acquired 639 (with only one original mag.). All three of them fit and functioned flawlessly. My question is, what other models can I take magazines from and use with the 639? I’d like stainless (and OEM of course) but other options would also be appreciated.

TIA ~ Froggie

These are stainless magazines but they also came in blue.
From left to right -

3913 magazine - too short, will not work in 639
639 magazine
Later 639 magazine with longer body and floorplate that closes gap
Currently produced 3906 magazine - works but sticks out a bit with gap.
Later magazines came in 8 or 9 round capacity.
No 7rd magazine works in the 639

Thanks. The one that came with the gun looks like #2 in the picture.
