You seem to think that the worst thing will happen. I personally would not try my own repairs on a hand gun, but you did.
I would suggest you obtain new mags, as recent ones have not had problems. Yours might have been from the time when there was mag problems.
Or you can assume that nothing can be done to fix your problem. I had a broken mag, total crack. It was replaced and has functioned for almost 2 years. Of course mine was a PT111.
Of course, if the gun is not over a year old they might ship you replacements, who knows unless you try.
