I agree with 1meanZ on the +P ammo. I don't use or practice with +P in my Shield 9 but do keep it in my Sig 229 9mm. I feel the shield is built a little on the light side to be using a steady diet of +P ammo thourgh it. While the Sig is pretty much a full size gun and over built for the 9mm. I don't practice with +P in the Sig either but do keep a mag loaded with it in the home. But hey that is just me.
