Oh, okay. You're simply asking what we carry as a minimum for EDC. For me, my most-commonly carried piece is a Kel-Tec PF9, which is often backed up by a P32. However, there are some times I cannot carry the PF9, specifically, at work, so I do not carry it there or while traveling to and from. The P32 is carried alone during that travel, and stowed while at work (EMS is a no-carry profession.)
Both guns are dead-on reliable with my chosen ammunition. This is the readily-available and affordable-for-proofing Remington-UMC 115-grain JHP in the 9mm and Fiocchi 73-grain FMJ for the .32 (though I am considering sourcing Fiocchi's Extrema 60-grain HP for testing for the latter.) They were chosen based on ease of concealment due to their sizes and weights, as well as ammunition capacity.
So I guess if you're asking about what our "bare minimum" carry is, the P32 would technically be it for me. But, other than the times mentioned above, the PF9 is on me at all out-of-bed times.
Like you, Dogsoldier, I am also former LEO, and my mind cannot shut that off, despite being out of it for over two decades (being in EMS now, I guess, continues that "desire-to-assist" mentality.)
