Yep, there's a review and pics on gunblast, the URL is already in this thread up above:

First issue is that I hope it's 7.5" long as measured parallel to the barrel, for the Calif market
.
Second, I'm not sure I like their bird's head grip. I'd have to feel it of course. I suspect that for modest power levels around 45ACP or less, the NCO Lightning frame would be nicer
. More than that might beat the hell out of the web of your hand.
Anyways, if you started with a 4.6" barrel model which can often be had at discount and add the NCO frame, you'd be at around the same price as the Ruger factory bird's-head. Or you could get a double-caliber Vaquero which is available in the 4.6" tube but NOT the Sheriff's models, and add the NCO frame...so far, the Sheriff's have been single-caliber only and adding a second fitted cylinder later can be pricey. So far, the double-caliber setups I've seen include:
.45ACP and .45LC
.357 and 9mm
.38-40 and .40S&W (the latter can easily be converted to 10mm or 10mm Magnum!)
The Qualitas grip frame also has a decent reputation, and can probably handle bigger recoil than the NCO.
