I am a new handgun/Glock owner. This is probably a dumb question but I am unsure seeing how I am such a newbie. I read you can't shoot lead rounds out of a Glock. I have a Glock 23. Are Lead tipped rounds only reloads? I went to Walmart to buy some cheap ammo and all they had was Remington UMC .40 S&W 180 GR. JHP, they were cheap $34 for 100 rounds so I bought them. Can these be shot out of the Glock?? There is lead exposed in the hollow point and will that interfere with the barrel??? Or do all hollow points have exposed lead centers?
