The 1911-style pistol is one of the most popular around in the commercial market and many sporting venues, and that being the case it generates a lot of opinions. Lots of companies are making them now, too.
As a firearms instructor I've seen my fair share of all brands of 1911-style pistols come through the range. Affordable and not-so-affordable.
I've worked alongside a very experienced armorer who put together some very nicely done Colt's and I've dabbled a bit, now and again, although my formal training is limited to just that of the Colt Model O Pistol armorer training.
As a long time owner of Colt pistols including 5", 4 1/4" & 3 1/2" models I've seen some that ran fine without any work, and some that required a bit of work. My latest Colt, a XSE stainless Government, ran just fine right out of the box ... although the aftermarket ambi safety assembly Colt used on that model broke within the first 200 rounds.
The folks who have been most pleased with their 1911's throughout the range sessions where I've been present have included those folks who could afford the more expensive customs (which aren't without their own occasional foibles, upon occasion, as tightly fitted guns can be less tolerant of cleanliness and ammunition than less tightly fitted guns) ... and then those folks who bought more affordable guns made by Colt, S&W and Springfield. I've seen more owners of Kimber and Para experience issues which required the services of a warranty dept, a gunsmith or an armorer than some of the other makes. However, I won't pretend to offer an explanation or suggest the size of the sampling means anything other than just that those owners I've known have had those experiences with theirs.
I do think that magazines for the 1911 are given less attention than they deserve, as magazines are at the heart of optimal feeding & functioning in all magazine-fed pistols, but seemingly especially in 1911-style pistols ... and there are a wealth of magazines from which to choose, too.
Then, not everyone may experience the same level of functioning and satisfaction using the same mag in different guns, even of the same make..
Then there's the ammunition and normal maintenance (especially lubrication) influences to consider.
Personally, I prefer not to spend more than $700 - $800 any 1911 which is going to be relegated to the role of a general range & 'working' gun (by which I also mean a carry weapon), but I've been lucky in being able to pick the last couple of them at armorer purchase prices. I look for quality of manufacture and support. This includes knowing the gun's manufacturer uses good quality vendor parts if they aren't making all the parts used in the gun, too. I use good quality magazines which I confirm function well in my specific guns, and I use good quality ammunition for both training & carry.
I know folks who like to spend significantly more, though, and that's fine since they can afford it and enjoy owning guns made by some of the big names in the custom field. That's what disposable income is all about, right?
I know one experienced shooter and instructor who apparently doesn't carry a 1911 that costs less than $3,500 or more.
I have toyed with the idea of ordering one from the Colt Custom Shop some time. I recently handled a friend's new Colt Special Combat Government (Hard Chrome, target sights) that was very nicely done. It was tight and yet felt really smooth when manipulated by hand. It was just removed from the box so it hasn't been fired, yet. I plan to try it a bit later.
I've also considered picking up a S&W Performance Center model. Some are pricey, but the PC's experience, reputation and support is pretty well established.
I've handled and fired some Wilson CQB's, and while they were nice guns which fed, functioned and fired well enough, I just didn't see how the price was justified ... for me. Of course, I've also had the opportunity to handle and practice with some Colt Gunsite model pistols, and I felt they were also just a bit over priced for what they offered, all things considered.
It depends on the customer and his/her preferences, desires and tastes, though. Somebody is likely to make something that appeals to just about anyone who wants a 1911-style pistol.
While I like to maintain my 1911's as recommended, I also know that my Colts & SW1911 will run and function well, even if left dirty between range sessions for anywhere from a few to several hundred rounds (but they're not carried unless clean & lubricated). Sometimes a few drops of additional oil may be added to the slide & barrel if they get really dirty and hot during extended/sequential range sessions in order to keep them running trouble-free in my hands. I've handled and used more tightly fitted custom guns which weren't so tolerant of those sort of conditions.
You get what you pay for, as with most things.
