Have both a nice S&W 1911 (not $3K in it, but maybe 1K) and THE Glock 19. Anyway- I've shot Expensive Kimbers, STI, etc. yes they are as SpeedRacer said "Works of Art". Glock is also a work of art kinda..maybe modeling clay art... So I guess having an $3K 1911 it is like having a Cadillac Escalade: expensive, lots of costly options, great to look at, fun to drive, everyone goes "Woow", but needs lots of care, polishing, stains easy, and don't want to go off road and get it dirty. The Glock is like a Ford F150: Works, cheap to operate, lots of options, fun to drive, everyone goes "Yea Ford or I hate Fords", easy to maintain, and likes it dirty.
I run my $3K WC in classes, carry them everyday. I keep them clean and lubed, but hell, did that to my Block when I owned one. It does not stain, and I am not scared to shoot it dirty. Very easy to maintain.
What extra care do the high end 1911's need?
