I own one - I purchased one of his Ultimate Black Widow's in 44 Magnum. I choose the 44 Magnum just to be different.
I find his work to be very acceptable and this particular Black Widow is very accurate by my standards.
At the range I have noticed a few snicker at the "engraving" but most of those "shooters" couldn't hit a cow in the ass with a handful of flax seed at 2 feet, so I just tell them it's different but damn accurate and then go on to prove my point.
If you decide to purchase one, I for one, think you'll be very happy with it.
