I have found a fix for the PM9 mags that won't drop by them selves.
Remove the spring, or depress it with a pen or something, then take a pair of channel-lock pliers and squeeze the feed end of the mag. Do not bend it just flex it together, it doesn't take much.
I have tried this on 8 mags, all new and all didn't drop freely. ALL 8 of them drop and function perfectly. This applies to 6 round as well as 7 and 8 rounders.
EASY FIX AND REAL CHEAP.
