I must respectfully disagee.
I've had my Clipdraw for three months now on my Lightweight Commander. It's fabulous for my needs.
I usually carry the Colt crossdraw in my denim shorts with an untucked t-shirt. When combined with a thick belt, the clip holds just fine in my tests...which consisted of running and jumping around.
The best parts for me are no added width from an IWB holster and adjustable rake. IWB carry has usually been an uncomfortable experience for me.
This makes the Clipdraw equipped 1911 quite comfortable to wear.
