Hmmmmmmmmmm, good question. I have a CS 45 that gets a lot of carry time. I have a 6904 that would once I get qualified. While I am not the biggest 9mm fan in the world, It tucks into the waistband very nicely, and with an extra magazine in my pocket I have 25 rounds available, that is an acceptable off duty carry. 6900 series gun probably tops the list then.
