I don't have any experience with the XDC-9, but I do have a Wilson 1911 & have had a couple of others.

I'm a Wilson fan & overall, they do a great job & I've used lots of their parts.

I would not hesitate to buy anything they make, but depending on exactly what it is & what you are trying to accomplish & how much you are willing to pay, sometimes you can get something similar that, in the practical sense & in the end, does just as well of a lot less $$$$.

But if I wanted a single action, 1911 based 9mm & was willing to pay $3,000, I wouldn't hesitate to buy the XDC.

Ditto for one of their compact 45's & those shoot like a dream, I can imagine the XDC is even better, being a 9mm.

There is always the intangible of what you personally, want to have. The 1911 that I have currently is the smoothest 1911 I've ever had............the slide literally feel like it's on ball bearings & it's more than accurate enough.
