So I was looking at m PT145 today and I noticed something. This is kind of hard to explain so please bear with me. If I look at my other pistols the barrel sits right in the middle of the whole in the front of the frame. Basically the barrel is centered in the frame. When I look at my pt145 that isn't the case. The barrel isnt centered. The bottom of the barell touches the bottom of the frame and there is a small gap at the top. Is this normal?
