My wifes M&P9c is the same.  Normal mag holds 12. But 10rd Hawaii mags hold only 9.  I can put a 10th in , but it wont load with the slide forward.  So no tac-reloads.

These are all 6 of her 10rd mags.  There are vids of people shaving part of the follower, but I don't want to do that, nor do I own a tool to do it.

No problems with the VP9 or P10C.

Were those mags originally standard capacity (12 rounds) that were blocked to Hawaii's legal max of 10?  If so, how were they blocked?  For the majority of the mags that I have that were blocked, a stick of plexiglass was epoxied on the underside of the follower.  That can be filed down pretty readily.  I started to do that to the PPQ mags, but ended up just using the 10 round factory mags that seem to be able to be depressed about the height of 1/3 of a round past the 10th round.  I was planning on filing the stick that blocks the mag to get it to match the height of the factory 10 round mags. 

For my blocked CZ mags, I think the follower hits a depression added to the tube of the mag.  In that case, I didn't want to try altering the follower itself.  If that's the case for your wife's M&P9c, I'd say I would 50/50 modifying it or just living with it. 

Wouldn't be an issue if Hawaii went with standard capacity mags. . .   

On a side note, armed mall security and plain clothes cop stopped the robbery. Who all 7 are illegal immegrants.

Security could have been killed if they wanted to. He didnt check his corners. PD did and saw 1 guy.
