So yesterday I bought a Beretta 92F magazine because it looked similar to my baby eagle magazine. Unfortunately there are some differences. The Mag catch is in a different spot, and the slide lock is lower on the 92f. So I broke out my hack saw, file, and dremel.
I cut the notch for the mag catch with the hack saw and cleaned it up a little with the file.
Then I took a chunk of wood. Just so happens I had a nice scrap piece of cherry. I took the dremel and proceeded to copy the follower from the 92f but with a higher slide lock notch.
