M&P9 mag question

[TriggerHappy]

Will the 9c 12 round mags fit into a standard mp9? My guess is they are to short, but the standard mp9 comes with 10rounders.

No, the compact mags will not fit into the full size frame gun. The 10 round limit you have is part of the follower in the magazine, not due to it's overal length. The hi caps for the M&P are 15 or 17 rounds and the same length, just minus the restrictive follower.

Thanks.
