Yes, I do in both carry guns.
My open carry gun is a SA1911A1 designed to be carried in Cooper Condition one - round chambered, full magazine in place, hammer back and safety on. It is carried in a Blackhawk SERPA with two retention devices, an adjustable draw tension that requires a draw parallel to the device, and a trigger guard latch.
My concealed carry gun is a DA/SA H&K USPc .40 that I carry in Cooper Condition two - round chambered, hammer down with control lever in FIRE because that's the way I trained.
I do not carry my Luger, and I keep it's chamber empty and the safety off because the safety is ineffective and easily defeated. It is not a self-defense gun so there's plenty of time to prepare to fire.
