Ruger P95DC 9mm (15+1) 124gr Federal HydraShok.
Depending on various factors, on other days I may carry any of the following:
-- Bersa T380CC .380ACP (8+1)
-- Bersa UC9 9mm (13+1)
-- CZ-75BD 9mm (16+1) don't carry this one often, due to size/weight, but it does make it out occasionally.
I used to have my Ruger SR9 9mm (17+1) in my carry rotation, but it fell out when they announced the recall. If and when I get it back and if and when I successfully test it to be reliable enough for carry, it might make it back into the rotation.
My 'nightstand gun' is usually whatever I carried that day.
