I carry a steel Commander sized 1911 (in .45 acp) daily.
I own a DW 10mm CBOB, and as soon as it works correctly on a daily basis I will add it to my carry rotation. It is probably my prettiest 1911, and I am intrigued by the 10mm cartridge.
However, I've owned it a year and a half, and it is still a range gun, due to an ongoing list of reliability issues. We are making progress, though, so I still have hope.
