Does a M&P 9mm compact have a unsupported chamber? THinking about beginning to reload for it & wondering about the brass life.

not to sure what an unsupported chamber is but i have an m&p in 357sig and says very clear in the manual to only shoot brass loads... if that helps

I've shot brass and aluminum out of my M&P 9mm..no problems.

I believe the M&P chambers are fully supported.

Only semi-professional reference I could find was a GunBlast article about the 40 S&W version.

+1. Have shoot everything from Wolf up in my M&P 9c

I'm pretty sure that they are supported chambers, but don't have any reference to back it up.

Call up S&W and ask. Then let us know
