Model 59 Magazine ?

[Chippp]

I recently acquired a 59 with 2 magazines. The magazines are not the same.One has a S&W..9mm..A and the other has no A.
The followers are different also.Which should a 59 manufactured 1976-1977 have?

Also one mag is very hard to install and will not drop free .It also binds up the trigger draw bar so bad it will not set the trigger. (You can see it with the grips removed)The other and my 5906 mags work fine. Its like it is to fat? Any thoughts?

Thanks
Chip
