I never just drop a handgun in my pocket. Even with a mouse gun (NAA Sidewinder) I use a pocket holster.
I place a lockable case in a secure storage area liker a trunk. I place the weapon there prior to arrival at the place where I have inability to carry.
So far, I'm still able to use a Semi, but fully loading the clip is getting increasingly difficult.
While dropping a gun into my pocket isn't ideal, sometimes, particularly in the summer when I have to run an errand in the neighborhood (I live in the city and walk to a lot of places), that option is just incredibly practical and attractive. I know I'm going to do it from time to time.
Usually, I know well in advance that I'm going to be entering a place where guns are verboten (football/basketball games). Even though I'm legally permitted to carry there (LEO status), it's not worth arguing with some 75 IQ security guard and his 75.1 IQ supervisor. So, it'd be a 3 hour proposition in a heavily patrolled parking facility.
My point about vehicle stowing is that I don’t want to be possibly seen at the parking site stowing something away — just makes my car a target. Therefore I stow the weapon when I se t off or in route.
The pocket thing is pure safety for me. I know I have set off car or house alarms by an inadvertent bump or rub on a key fob. Is an unshrouded trigger more immune.
Just my two cents. Stay armed. Stay well.
