I've been looking around at a lot of various places for ammo and ran across Underwood ammo. Their .40 is all labeled "+p", which I know is a marketing plow, but they have some crazy numbers.
135 grain 1500 fps
155 grain 1300 fps
165 grain 1200 fps
180 grain 1100 fps
Are these rounds safe to shoot in glocks and m&ps? Or are they far over reaching safe pressures and speeds?
