The 44 looks terrible, the 42 looks perfect. You made the right choice. The only question I would have is how old are you? 5'9" and 125 is very thin, and if you're under 23ish (age) I could see another 10-15 pound in your future in which case the 42 could start looking too tight. Not sure if you care to look that long into the future and the leather will stretch, so you should be fine. I'm a bit jealous really that looks so good.
