Key principle: one is zero, two is one.
Get more than one, of the same caliber, as a backup.
In an “after” situation, you can’t go to the gunsmith or get parts online.
As with many of my preps, they are incrimental. My SP101 is my current goto for immediate bump in the night defense. I have many other arms to fall back on.
That is a very good idea, thanks.
