I have a 9mm shield, my son has a G43 9 mm and a G 19 9 mm, I ordered a couple boxes of 9mm 147 hard cast and just looking for experience with these guns and hard cast BB ammo. From what I have read, Glocks can shoot hard cast , Is this correct? We are using these for hiking, archery season, and just bumming around the woods. Please no, " get a bigger gun", we have those and just like shooting and carrying these.
