I voted for Wilson (based on their overall reputation), however earlier this year I bought a Springfield TRP in ArmoryKote. The TRP's fit, finish, quality, durability, reliability and accuracy are first-rate -- simply outstanding. This is one tight, well-manufactured 1911A1.
At ~$1100, the ArmoryKote TRP is at the low-end of the $1000 to $2000 range specified in the thread. I am not certain that spending another 700 or 800 bucks for a mid-grade Wilson or Baer would be worth the marginal investment. I am not knocking either for these fine manufacturers; rather, I respectfully suggest that -- for me -- the incremental differences may not be worth the additional cost.
Our friend, ArmySon, has commented on this question before -- I suspect he disagrees with my opinions (above) -- and I will be very interested in his views.
