After owning several poly Kahrs and later selling or trading them in, due to questionable reliability issues, I've recenty purchased an all steel MK40. I currently have three choices of ammo and I'm wondering if anyone has carried any of the following and what they think about it. Having had reliability issues in the past in other guns, I'm first and foremost concerned about ammo that will cycle and perform reliably. Second concern would be overall performance, specifically performance, keeping in mind defense from humans and also as a back up woods gun, so potentially against cougar and black bear (last ditch back up that is). I'm not worried about recoil at all. Winchester PDX1, 180 gr Winchester Silvertip, 155 gr Buffalo Bore +P 180 gr I picked these three, because that's what I currrently have in stock. Other choices that I might consider, if I can find any, are Speer Golddot short barrel, 180 gr Pretty much any other Speer golddot load Buffalo Bore +P, 155 gr (with speer bullet) Any concerns or comments on any of these loads in any of the Kahrs or any other loads you might recommend? Thanks much.
