They certainly are extensively detailed. And from what I have read from owner surveys, their functional reliability rate is the best of any 1911 manufacturer, slightly edging out Baer.
But for a working gun I think I'd go with a Baer. And if I was looking for a piece of tactical jewelry, I'd look at a Nighthawk. Both of which are a couple grand less than Wilson.
