I don't know if it's been asked before, but I just noticed it today on mine. Has anyone noticed their mags wearing through at the mag catch? I was testing out some mags today that I bought off a member here, and noticed it so I checked the ones I have had since new and they are the same. Right in the middle of the catch point they have a hole, not very big, maybe an eighth of an inch long. It's almost like the grind went a little too deep. Only noticed it on my 10 rounders, I didn't have the eight rounders with me. They all work fine and I have never had an issue, but seems odd none the less. Anyone else noticed this with theirs?
