Don't listen to those people. They are ignorant (or just plain stupid--you pick). Buy your glock with confidence. If those people only own hunting rifles, they are woefully misinformed (or Fudds).
You live in Kalifornia. The brown suits will have searched your house, confiscated your Glock and placed you in a re-education camp long before it gets old enough to crack.
I waited 25 years expecting them to crack, melt down, or just disappear. None of that happened so I bought a couple of them for myself. So far so good.:biggrin2:
