Im new here, but been looking around for a little while. Just thought I'd share a stippling job I did on my daily carry weapon. I've also done some glocks and other M&P's. I like doing things myself.
Nice job! I have a grip insert that was done just like that by Speed Shooter's Specialties.
IMHO, the M&P is the best poly on the market. I've seen a few with super slick triggers in them too.
