I opened up the mag off of our styled L and it has a piece of insulating material in that area. I don't know if its OE or not, but it might be in there for this same reason. I'll get a pic of it and post.Oh yea I've had that happen in those tight spots it easy to have something move just a bit and short it out I've slipped a length on shrink tube over the spring to insulate it to help
