I'd like to know the correct skivvy on whether you need to register a KelTec sub2000 with a local police department in MI? I've heard that you may because it folds in half; to about 16 1/4", I believe. I've also heard if you DO register it (assuming you don't legally have to; IF it's categorized as a 'long gun' - you can legally carry it in the trunk of your vehicle; with a CPL, which I have.
- Can someone who knows please clarify for me here?

- Also, is it true you shouldn't fire aluminum cased ammo out of one? I'm awaiting my 40 cal. version from Gunbroker's - want to do things right. Thanks to all who can help!
