I normally prefer American all steel handguns, larget calibers as .40 & .45 but
I was watchiong a Texas Highway Patrolman buying a rather inexpensive hide-away gun for an ankle holster. I asked to see one, a Kel-Tec PF-9. 9mm.
It is double action only, no firingpin retained to maybe go off if dropped, no safety, just a double action trigger that raises the hammer and she goes boom. I can hit soft drink cans at gunfight range and I load 7 hollowpoints in the mag and one in the barrel. It feeds my truncated cone hollowpoints as easily as round nose ammo. I can carry it in a pocket holster in my jeans
side pocket. Yes its plastic and steel but I consider it a very safe small firearm to pack in the pocket. No it won't put a zombie down like a .45 but eight holes should slow him down.
I second Cuate on the PF9. Pretty accurate, hasn't jammed in 100 rds, fits in hip pocket. Only thing I don't like is the mag follower is made of SOFT plastic and soon deforms so as to not lock slide back on empty. Still feeds fine tho.
