My m&ps eat everything. I stopped using WWB because I kept finding flawed rounds almost every other box. Most 9mm range ammo is 115g. Sd/hd ammo can range from 90-147g. I stay in the middle with 115-124g. I shoot whatever for practice and speer gold dots for hd/sd. Wally world has been pretty good to me for finding range ammo. Picked up 300rds of 9mm brassmaxx sat for $80. The gold dots cost about a dollar each and are stocked by most gun shops. I a little bias about handgun magazines, only mags from the manufacturer for me. usually cost around $30. Buds guns & midway usa are a few places that come to mind.
