Howdy,
I always carry OWB and use a loop through holster ( Glock Sport holster for my Glocks ) or a belt slide holster for my PF-9, Taurus PT 845, 1911, etc. and any time I need to remove my pistol to enter a "No Gun" place, which is very rare. I just unholster the pistol and place it under the armrest, leaving the holster on my belt.
I've been carrying for over 33 years and I can unholster and reholster without anyone being the wiser.
Plus, I've never been a fan of the Fobus type paddle holsters. It seems like every time I bend over, twist, turn or even move they want to pop out.
Like IWB carry, they aren't for me.
HTH and your mileage MAY vary.
