I am also from Maryland, ride a motorcycle, and like to carry when I'm in PA, Del, Va, etc.
While on the bike, I usually don't plan on pulling out the gun for the reasons stated previously. For me, carrying while on the bike is just for convenience--so I don't have to leave the weapon on the bike or off of me. It stays on me and stays concealed
I've used several holsters, but what I've found best for me is the NRA Tactical Holster--I like it's overall concealability factor in general; sits on the waist comfortably, no issues getting on/off or riding the bike. I know there's lots of debate about having a weapon in one's groin, but like everything else, with the right weapon, training, awareness, and using the holster as it was intended, I find it works well and very safely.
