So I bought the 19 today. Didn't like how my hand felt on the 26, just didn't have enough grip for me. The 19 seems like a perfect fit. So, since I have a bunch of Tulammo 9mm, will this be okay for this gun? I know Glocks eat anything but still curious what everyone's .02 cents are. The saleswoman, who seemed older but not too knowledgeable said she would never use steel cased ammo ever. For what that is worth..
