My great grandfather’s pistol is ninety years old and though not a show peice, it isn’t damaged by corosion. Put a little gun oil on a rag, not much, and leave the rag for wipe down where you store the pistol. It will last a generation or two unless stored on concrete which wicks sub-grade moisture.
Remember, it is a tool and doesn’t have to look shiny for its working life. Buy from a dealer with a range where you can fire various calibers. Buy the largest caliber you can fire and place back on target after the kick. A defense pistol is stopping power. Concealed carry is another issue.
Keep in mind, if I had been your kid, I could find every gun you have in the house — I did in mine growing up — but the proper respect kept me from outright abuse of them. I consider this with my grandkids now.
“A defense pistol is stopping power.”
Will definately keep that in mind!
