to fit in the hole

Sure the problem is not with the magazine catch or the magazine colliding with something inside the magazine well such as the center support?

If the rib on the back of the mag (what the latch clicks on to) keeps the mag from locking in, sometimes you need to take just a little material off the rear of the mag well and the selector stop. It's not much, take a little at a time.

I'm using those in my pistols, on tapco flats, didnt have them but since my mags are plastic and us made i decided to trim those instead. I did trim the area where the mags latch in on my rifles, also tapco
