I would suggest that you do not handle your firearm in the presence of a LEO who contacts you.
Be calm, confident and cordial. Defend your rights in a manner that is polite yet firm. Know the law(s) and keep chatter to a minimum. Heck, even maintaining a smile will go a long way in keeping the level of tension down to a bare minimum. Not every LEO is out to hassle you or infringe upon your rights. But, you will not know this until it happens. Regardless of the circumstance you are at the pleasure of the LEO and your maturity level will bode you well in the outcome of the contact. Adults tend to treat other adults as adults.
No one here can tell you what to do, we can only provide anecdotal evidence and impart our experiences. Each contact is unique and the outcome is entirely up to you and the LEO.
Please understand that LEOs are not out to get you.....until you are contacted by one that seems to be out to get you.
Carry a recording device and be safe.
