Hello everyone. I'm new here and this is my first post. Im a new gun owner. I bought my JCP 40 new. I put about 800 rounds through it and cleaned it. After I put it back together I can hear the firing spring move back and forth in it. I know its not the drop saftey. I can see it through the mag well. Is this normal? I don't think it did that before I took it apart. If I rack the slide it stops of course and it dry fires fine. Can anyone shed some light on this for me please?
