Yea.....I'm finding that out.
I ran across a good deal on Fed a while back so I picked up a couple of bricks.
It seems to function is a couple of other auto's I tried it in but I get a lot of duds.
I'm down to about 50rnds and won't be buying any more.
You're right about the Auto Match though.....it's flawless in my MKIV and Browning 1911/22.
Walmart keeps a pretty good supply of it so I go through a lot.
