I'm not saying it'll work, because I haven't actually tried, but it seems like it would make sense... The extension on the 10-round 30 mag seems to be just like any of the other extensions out there, but it's just shaped to be a pinky extension.
No u can't make it a 9 round mag the mag is to long and the baseplate is actually flush on the 10 rounder even though it looks like an extension...
