Great Question OP!
I carry my G26 almost all of the time on and off duty. Monday through Friday I carry an LCP as a BUG.
Sometimes if I'm working and the occasion calls for it I carry a G17 with the G26 as a BUG and the LCP as a deep cover BUG.
In cool/cold weather I will carry the G17/G26 combo in a duel shoulder rig. Sounds a little silly but its a very comfortable way to carry a lot of firepower.
I've carried many other gun and gun combos thoughout the years, I have to admit that these are my all time favorite. Maybe not the sexiest but the most comfortble and comforting.
