I just got my hands on a M40, and was sad to see that the key for the safety is not in my case. is there a place I can get a hold of one of these. I am kinda tired of using a paper clip.
Make sure that it's not squished into a slit in the foam inside the case, mine was virtually undetectable until I started pulling a little on the foam inside the case, and the little slit with the key in it was revealed. Hope this helps! ~Rick
