I don’t know anyone who owns a gun.
I know you have to remove the clip and make sure the chamber is empty before cleaning a gun so you don’t shoot yourself or someone else and to watch out for recoil. Keeping the safety on when necessary is something else that I know to do.
Then you definitely need to go to a good shooting range where you can rent guns and get some instruction.
By the way, don't worry about clips and safeties, etc. Start with a simple double action revolver and work up from there.
A word of warning: once you start shooting you will be hooked.
