I'm building a 1911 for my son. Which barrel (full size, 5", 45 ACP) would you all recommend? I've been looking at the Wilson Combat Match Grade barrel or the Ed Brown drop in Match barrel. Out of those two, the Ed Brown costs less and will probably require less fitting than the WC. I have never fitted a barrel before, so hopefully its not that big of a deal. Any advice would be appreciated. Thank you.
