I don't have a CPL, I've OC'd
on several occasions.
You have to keep your gun locked for transporting.. I keep it locked in my ammo box. I keep a full mag + 1 round also in the same ammo box.
I keep my holster on my belt, empty, from the time I leave the house..
I get to where I want to carry, I take out the gun, unlock it, put the magazine in, release the slide, decock the gun, pop the magazine out, put the extra round in, put the magazine back in the gun, then put it in my holster and button down my retention strap.
Never had a problem with this method. I just make sure the gun is only loaded when its outside the back of my Jeep.
I would try not to look like you were being hasty and not careful. I would take my time and do things the right way, rather then rush it.
Brandishing is waving your gun around in a threatening manner.. A cop would be hard pressed to nail you with this..
