Yes, PA is the same. As long as I feel threatened, I will not be arrested for using my gun as a CCW holder. The civil liability cases are a different story in some states, but PA has a castle doctrine which includes your workplace, home, vehicle and eminent domain. I am not concerned with civil cases... If I feel I need to use my gun, I am ready to.
Also, Cartwright: This is the same location I had it mounted when I was pulled over in the past. You cannot see it from outside the vehicle. Front drivers side window, the angle is too extreme and it is covered by the dash. Back drivers side, all passenger side and rear are covered by seats and/or center console. In one instance, the trooper didn't even think about asking me where they were, and handed my license, CCW card, and insurance right back to me and asked me to slow down. In the other instance, I handed him the card with my insurance and license and had my hands on the wheel. He asked if I minded unloading the weapons while he runs my information. I remove the magazine from the one onto the passenger seat, and cleared the chamber and set the gun on the passenger seat. I then removed my S&W J frame from my waist to unload it, and he said, nevermind, don't worry about that one. (Maybe he figured ehhh, what are you gonna do to me with 5 shots from a 38 sp +p, from a 2.5" barrel haha)
Anyway, my logic has always been the same about carrying... if I am ever at the point again, where I feel threatened enough to PULL my weapon on someone, there will be no hesitation for FIRING the weapon. I am a firm believer that concealed means concealed, and do not go around flashing this around as a power statement...it is a tool to protect myself, family, friends and property.
Once again, this was not intended to be a gun debate, but since there is enough opinion out here already...why not...
