One of my friends has a CQB. It is a beautiful handgun, nicely finished, and silky smooth in operation. As noted, the Armour Tuff isn't so "tuff." He already has some holster wear-and it isn't his carry gun. Also, while we were doing some running and gunning on multiple targets (our own low key IPSC!), he did experience a single jam with ball ammo. The gun is quite new, and very tightly fitted. But still...
Anyhow, I own a few Colts and a couple Kimbers. The finish on the WC is superior to them. If I were in the market for a higher end 1911, I would definitely consider the CQB. I've also read that the tightly fitted Baer 1911s can also be quirky until they have been broken in.
My favorite shooter is a 1991 Colt Gov't, lightly modified with a better trigger and a steel arched mainspring housing. This sucker is showing a little finish wear (no surprise, as it has covered quite a few miles and about 9 years with me) and has a few thousand rounds down the pipe. But it is dead reliable and quite accurate. Not as accurate as the CQB perhaps, but it goes bang every time I pull the trigger.
