Are you sure it is not the Extractor arm????My new BT 380 has,what looks like a "shell in the chamber" indicator on the top of the slide in a small indentation about 1 inch behind the extracter port on the right top of the slide. If that is what it is it doesn't pop up when there is a shell in the chamber. It stays flat in all situations. There is an indicator on my Thunder9 ultra compact Pro that is very ovious and works perfectly. Is this a big problem, or am I overly concerned about no big deal????? anyone???? Thanks
