Just purchased new M&P 9c # 209304 no lock,no safety,no mag. safety & 12 round magazines . Haven't made it to range yet to test it out . My fourth M&P if you include my 15-22 . I really like them .
Congrats! My 9c has the mag safety since it was the only way I could get it with night sights at the time. I actually prefer shooting it to my 9FS. I think that you will like it.
I have one of these and it's a great shooter. I also added a .40 compact, but haven't gotten that one to the range yet. M&Ps are awesome guns in my opinion!
