I did for a short period of time, Smith Gun sight edition and depends on the season really. My level of threat no longer requires me to carry a firearm daily though. If anything it's a small .380 when I do. I find mac is pretty useful and will get me into far less legal issues while minimizing the threat.
I've been carrying a G21 daily, year round for about 4 years now. It weighs less than a 1911 but I'd say they were about the same size. I carried a G17 before that. OWB Blackhawk Serpa Holster, too fat for IWB. I don't even notice it's there anymore.
