Caspian, FWIW, gets almost a grand for their damascus slides
Someday I might build a Bar-B-Que 1911, with all kinds of fancy doo-dads on it. It is not difficult to make grips for a 1911, so there's hundreds of different styles available - everything from mammoth tooth, to aggressive G10, to engraved sterling silver. And many of the other parts are available in custom configurations.
There was an extensive owner survey at 1911Forum a couple years ago, with hundreds of people rating the reliability of their pistols, as far as malfunctions in the first 200 rounds. H&K was actually the winner, with something like 4% failures, Glock was about 10.4%, and Wilson Combat, and Baer were about 12% & 13%. Colt was the best of the production guns, at around 17%. So a really good 1911 will be in the same ballpark, reliability wise as a Glock, but H&K beats both
I've owned two Glocks, a 2nd Gen G22, and still have a 4th Gen G34. Neither was especially accurate, but both have no malfunctions. I am kinda pizzed at the G34; I would expect a long slide target pistol to be tightly fitted, but it's about as sloppy as their other guns. It does run flawlessly, but I don't carry it, nor completely trust it without a manual safety.
When I decided to get another double stack 9, I eventually settled on the H&K P30LS, as I like the safety, and to me it points the best of any of the poly frame pistols. So far it shoots very well, and does not jam.
I've owned or shot a pile of 1911's. Some of them I trust completely, and some are toys only. YMMV. But I do get a gun that is easy to shoot well, with a metal frame, that is easily customized and tuned. And if it does not run 100%, it's really not that hard to fix them.
