When I CC, its normally in a leather, open top speed holster with simple friction retention.
When I OC, its normally in a leather thumb retention or Serpa style button retention holster, and it has to be fixed to my belt by loop or multiple teeth that cant be pulled off me without tearing my pants first.
When at home, or other private location, I just use my open top leather.
When around kids in a private setting, same as at home, only without a round in the chamber.
I mostly like De-Santis or Galco pancake styles for a cheap and functional leather holster, but custom leather is good to if I have the money.
