My favored primary CCW is my slightly modified GI WWII Champion backed up by my Taurus PT-145 carried in my front pocket.
I also have a Springfield Ultra Compact Mil-Spec that I have modified the grip safety tang and shortened the hammer on. I am at about 300 rounds with no failures as of yet. It could replace the GI in the future for primary CCW.
The Taurus is my only office carry since it slips into my dress pant pocket and is all but invisible.
