If you want a G.I. style gun, go with the new SA Mil-Spec. Don't worry about the finish, the G.I. guns were parkerized.
If you want pretty, you gotta pay for it.
I understand what you're saying about the look and yes that can be changed but my old well used 1911s are 20 plus years old but action speaks louder than looks and mine will work all day. My question is will you get to run a couple rounds thru it B4 you cross the palm of the seller. Welcome to the party and good luck.
Scuff the finish up a little, it'll look like "Smoked Nitride", a popular finish from Nighhawk Custom without the cost. You'll be the envy of all the cool kids.
