I agree, looks intriguing. That said I have not come across anyone yet that owns one. Personally, since I primarily shoot target without the need of a holster my 220 in DA/SA suits me fine. Once I chamber I am always shooting in SA until I run empty and rarely need to decock and shoot DA. Frankly, my groups suck in DA so I try to avoid it altogether. I suppose if you could carry or did a shooting sport being cocked and locked on the SAO would be more useful.
I will concur on the 220 being an excellent shooter in general.
