Funny you should ask. My money pit is a Kimber Custom that just wasn't custom enough. I had a S&A mag well/mainspring housing (stainless), a Clark fully supported barrel(blued), front strap checkered, Dlesk trigger and trigger job(stainless), Kings Match barrel bushing (blued), PT night sites , high luster finish (blued) and a slide to frame fit. I also bought two Wilson 8rnd mags. So far I'm in at $1200, or $1775 if you include the pistol.
Before the custom work the Kimber was rather dull looking, flawlessly reliable and resonably accurate. Now it feels great in the hand, looks fantastic, is more than resonably accurate and jams on the first and last rounds in the magazine. The smith says it needs a few hundred rounds through it for break in. I think he's right, the more rounds I put through it the fewer failures I get.
Untill the failures cease this is a range gun/conversation piece only.
Here's the thing. I used to be a die hard anti-1911 guy siting the need for customization as the fatal flaw of the 1911 design. For what I have put into the Kimber, I could have bought two "name your brand" that would have been reliable out of the box. However, this particular gun was a Christmas gift from my wife, which adds sentimental value. The customization process was fun and now I have a gun that is unique (at least to me). Maybe this was just a waist of money, but it is the first pistol I've owned that I would consider engraving with my initials (i.e. not for sale).
Sorry, I don't have a digital camera yet, but trust me she's pretty.
