I've thought through this several ways over the past few years. I keep a pistol in each of my 3 vehicles, locked in the tunk in one of those steel cable-tied boxes. The truck box is under the seat, until I find something better.
for me, it has to be
1 double action, preferable DA/SA
2 Hicap
3 9mm preferred
4 Under $300
5 Pocketable for CCW
So far only the Bersa and KT P11 come close at new price. but I've bought two Stoeger cougars LNIB for $310 each, and I like those but they are a bit larger for #5. I've only had Bersa 380s, and did not like the trigger on them. No experience with Bersa 9mm.
At new price, it's got to be Keltec P11, with 12- and 15-rnd mags. Proven, reliable pistol.
Right now the 3 vehicles have a Keltec P11, a Keltec P3AT, and TBD (in the shop)
My vote is Keltec P11
