Just for a smile....
Yeah, I'm new here and new to sidearms in general so I'm learning. I recently complete a poly 9mm & .22 build. My son and I were talking over the weekend- "How many rounds do you have Dad" he asked "A thousand of 9mm, a thou of .22" I responded. "Not enough" he responded.
Then I told him that I had really wanted to get more proficient with the poly19 before SHTF, he responded "Dad, you go into my gun safe and pull out the 590 Mossburg, it's #4 buckshot wll preclude your need to be "proficient" .....
My boy is a realist.........LOL
He does know a shotgun doesn't fire a solid wall of doom right ?
The 1" - 3" spread ( range dependent ) is a lot easier to manage than 9mm, but practice is still good.
I imagine you both know, because he did have a good line there
