I love blued 1911 for presentation purpose. Milspec/Loaded in Parkerizing is more utilitarian, but still look decent. Down side of the bluing finish include that it is not as durable in humid environment and show finger prints the minute you touch it.
Because of decades of new firearm finishing development, bluing is no longer the default choice for manufactures or most gun buyers. Colt is the only one still offer brush blued O1911C as regular production item. A few other semi-custom shop (Les Baer, Alchemy) still use bluing but they are not at the price range for average gun buyers.
Springfield recently bring back blued slide for their 2-tone Ronin. But I would also like to see SA bring back full blued Loaded and Milspec. I used to have this Ultra Compact in factory brush blue too. Sold it a few years back and still regret it until I got a chance to picked up Colt TALO CCO to take its place.
