Since I carry two spare mags on the left side if I lean over to get the registration there is the possibility that the officer may see them so I choose to tell them up front. Hasn't caused any extra time in the past but that isn't to say it won't on down the road.
Doog! Where have you been?
Clearly you need one of those little pouches that attaches to your visor, or maybe just an elastic band to hold your registration and insurance proof. You could put your wallet there when you're in the vehicle too. Then you won't have to do any reaching. The reaching tends to make them nervous.
