I defer to the pistoleros on choosing 1911's.
Probably, however, you will end up with a "match" piece and a carry gun at some point, so don't try to "blur" your first choice too much. Really.
Adjustable sights are "de rigeur" for a "range gun", but not, necessarily, for a carry piece, depending on their propensity to foul your clothes.
Colt used to produce their "Gold Cup" .45 which you could sort of rely on out of the box.
VERY Very Pricy.
I have no experience with the Para, and my Fed Ord experience is not positive.
If, however, Van says the Para will do both jobs it either will or can be made to. Having a good smith to hand is critical.
I use the services of a gentleman in Sandwich Mass., but he is not exclusivley a "pistol smith", and I used Fulton to rebuild the M1as.
Springfield offers some services on these lines, at least they did, but I was a. not completely happy with their efforts and b. it was some time ago.
Call the recommended smith, he sounds like a treasure.
Sometimes, however, you have to try the pieces once you have determined generally what you are going to do.
For example I determined I was going to have a Standard, an NM and a Super Match M1a. SA's Standard and NM were OK, but the Super Match had to be rebuilt.
This can happen no matter what you try. sometimes the dog just won't hunt.
Personally, I'd "try" the Kimber and see how it works (its there NOW) and make plans to contact Mr. La Rocca and/or for a Para ORD.
I certainly will be thinking along these lines, although my SIG 220 shoots fine for "general" range stuff and carry, single stack magazine notwithstanding.
Unfortunatley, I end up "carrying" a compromise because of size and I am in and out of the Registries of deeds a lot. The Local guys know me and don't mind putting my Walther (not terribly imposing) in a\the lock box, but, I am not really comfortable carrying same into Boston or Cambridge (Suffolk or Middlesex) because I am not known there and, I am sure the local chief would get a call from the guards. I don't need that.
This stinks, but I have to go along a bit.
Besides, I suppose the metal detectors give me a measure of protection too, but I would prefer to follow my own thoughts and not the State's.
