Lot's of good opinions running through here. At this point I am going to rule out custom building my own, maybe in the future. Though, nobody has mentioned any manufacturers to stay away from. I will go out on a limb assuming its due to the fact that the design has been tried and proven for a hundred years, and can be hard to screw up as long as the materials being used are decent?..? (Question/ Statement)
No! Absolutely not.
There are plenty of 1911s with problems. To begin with, 1911s take more hand fitting and are generally (though not always) not as reliable as many more modern designs. Feedway stoppages are a common issue. Common causes of failures to feed include improperly tensioned extractors, rough breech faces, etc.
Kimber has had lots of problems with their Series II guns, having gone through at least three different designs for their external extractor. I don't recommend the Kimber II models.
Both Kimber and S&W's pre-E-series guns use a Swartz-style firing pin safety. If the safety isn't timed properly, you can get a failure to fire. Kimber seems to have had more issues with this than S&W, based on what I've read on the internet (clearly not an accurate statistical sampling, so take that for what it's worth).
ParaOrdnance has had quite a few issues and I strongly recommend that you stay away from them. My P14-45 had the hammer start to follow the slide, has many failures to feed near the end of a magazine, and the slide stop is starting to peen the slide stop notch on the slide. My experience with PO is not unique.
Sig's early 1911s had many issues.
There are many different aftermarket magazines with different designs, and some work better in individual guns than others.
Some good 1911 makers include: Colt, S&W, Wilson Combat, Springfield Armory, Ed Brown. The new Ruger 1911 looks quite nice, but I have no experience with it and it hasn't been around long enough to get a reputation for good or bad.
