I find that most mag catches from quality guns have a slight slope angle to them. The purpose is to allow the pin to pivot the catch out of the way when you rack the slide. This is why racking the slide on a 1911/hi capa releases the slide catch.

Its not much but very slight. Like many already said, inspect the pins and spring to see if there is any damage or excessive wear to them.

If you HAVE to remove material, always go slow and steady and test and retest. With the cheap metal that these parts are made of, it is very easy to remove too much material.

But for academic purposes, if the pins and spring are perfect, and you absolutely had to break out the dermal, you could use the bit that is shaped like a ball and just put a small divot for the pin to sit in. Doing this would allow for the pin to hold down the mag catch a little bit better. However, try other methods before potentially ruining parts. But hey, mag catches are only $10 at most places anyways. If anything I have a spare TM one if you need.
