Sport45's post; my reply...
To answer the posted ?, a firearm is not a prop, toy or fashion statement.
It's a lethal weapon that can kill or injury someone.
It would be difficult for a jury or judge in open court to accept the "I bought a cheap, worn out gun." excuse in a use of force shooting.
You'd also need to make sure the pistol worked correctly, so if you are in a lethal force event, you are not killed.
A "beater" car make break down & cost you $$$. A beater gun may get you killed.
Every 2nd matters.
