Since the OP is referencing me, tolling me and using a pic of my pistol I will answer the question. I will state or the record that the OP has misquoted me from a thread which was closed. I did not say the things he is claiming. The pistol which I own that he has posted is a Colt 01970A1CS base gun. As
@Madcap_Magician noted it has had some custom work done to it. It was done by Don Williams of The Action Woks. Don is a member of the American Pistol Guild and one of the top 1911 smiths currently working on guns. He is a master craftsman and a true gentleman to work with. The $4,000 figure in the OP is not reflective of the real world price of this gun. It is an arbitrary number that the OP through out there and is still using. Those who appreciate custom 1911s can build a rough estimate in their minds of what it cost to build this gun. I will also state that this gun is currently worth more on the open market if I were to sell it today used then it cost me to build. This is what was done to the pistol.

The #1 reason to own gun like this is owning a one of a kind bespoke pistol made to your spec. I worked with Don talking about what parts I wanted to use. How I was going to use the gun and what I wanted out of it. I choose parts based on my needs and wants and his recommendations. The process was enjoyable and rewarding in and of itself. This gun is a functional piece of art which shoots 45 ACP bullets. It is about appreciating the craftsmanship that went into building it. Don is a craftsman. This gun has Better parts, better fit and better finish then it did when it left Colt. It has better performance from a tuned trigger, extractor and hand fitted match barrel. In this instance durability of the finish. IonBond holds up better than anything else on the market. After 3+ years of ownership going in and out of leather and kydex holsters it shows almost no wear. I am the first to admit that the law of diminishing returns is at play when you move up to custom pistols. You are paying 2X the $$$ to get subtle refinements which may or may not matter to you but they matter to some people and some people are willing to pay for it.
I will also state that a great shooter is great with almost any gun but the difference between the USPSA Grand Master and M Class are fractions of a second over the course of a match. The devil is in the details. A poor shooter is going to shoot poorly with a $300 gun or a $10,000. Most of us are somewhere in between. While shooting this pistol next to a stock Colt the difference might not show up on paper but the feel in the hand is completely different.
As others have already stated In this thread the OP is misrepresenting what I said. He misinterpreted my intent and my words.
