Folks -- I just acquired a DW PM7 in 45acp. It comes with 2x 7rds OEM mags. So I decided to also get a 10rds mag from CMC, hearing good things about the brand. Now: the 2 mags that came with the DW eject easily, once after pressing the mag release. However the CMC doesn't work like that: I have to pull it for it to eject. Is that normal? Do I need to oil the mag? or return the mag? Note: not sure if this is a factor, but I haven't done my field strip yet, as I have no idea when I'll be able to go to the range, given all are currently shut down. Salutations from SF, CA.
