I have owned one Wilson and was not impressed with it's accuracy compared to a Valor ... it sure was a beautiful piece of work though. And it was reliable.
Regarding issues with new guns, I just ordered a brand new, fairly high end sporting
s shotgun (around $5k) and when I got it, the trigger was sticky and did not reset reliably. I boxed it back up in the shop and had them send it right back. I know I could have fixed it but not for that kind of investment. Needless to say, I was disappointed ... but it happens. I am confident they will straighten it out.
