I just purchased a couple of the new brownells 30 rd. mags. My problem is that they don't quite line up with the mag catch. I have am OLY arms ( I know, I know ) and I know that the quality isn't what it should be. My question is should I file the mag catch slightly so the brownells mags will lock in place like my others, or should I open up the hole on the mags themselves ? I if file the mag catch, with it still keep my other mags in place ?  thanks

d00p!

I'm not asking for any names, just some suggestions that might help with my problem.

Just a quick update. I filed the mag catch holes (slightly) in the new brownells mags and they latch in just fine. So far, they seem to feed flawlessly. The only problem that i can see is that you have to give them a little pull to come out. I really think that  I just have crappy lower, butb I'll get it to work. Right now, I'm just glad that everything is feeding properly.
