Express is what I have used. I got the stretchy comfort band for it. I don't like scraping my cuticles and knuckles on the carbon fiber when drawing, so I covered the edge with a strip of moleskin. The non-Express might be more adjustable but the Express is more compact overall.
Bodyguard 2.0 is just incredibly small but it shoots well for me. Nice, easy to pick up iron sights. One of the magazines had a follower installed backwards, but that was easy to fix myself. One failure to feed on the first few rounds through it and has been running fine since. I haven't shot it that much though. Like maybe 200 rounds. It shoots .380acp instead of 9mm, so it's not quite as powerful but I think 10 easy to aim rounds is enough stopping power. Bear in mind James Bond and most European police forces used the even less powerful .32acp for most of the 20th century.
