Magazine for Beretta Model 70 S

So my wife and I were given a Beretta model 70 chambered in .380 with a couple of mags from her dad. Unfortunately only one fits with the slide catch. Wondering if it's possible to modify the other one to be able to fit. Finding mags for this thing isn't easy. I need them both to have the notch at the top.

Let me know how they are because I could use a spare. If you ever find a RH grip screw, I need one.
