As far as bugs go, there are a lot worse to have...
There is one simple a reason why just about every manufacturer worth mentioning (and a few that aren't) produce 1911s.
That is...because they sell like hotcakes.
Ask Ruger, who held out for many years, and finally built one. They can't build them fast enough to keep up with demand. I was on my LGS's wait list for quite some time, and finally gave up (she has a small shop, and is pretty far down on the distributor's priority list). Now that Ruger has introduced a stainless Commander, I may have to put myself back on the danged list.
Likewise S&W. I don't have the sales figures, but I would bet that S&W sells almost as many 1911s as they do 642s...and the 642 is S&W's best seller, year after year. Bear in mind that S&W's average 1911 sells for at least 2x what a 642 sells for. Yes, I own two of their 1911s...and no 642s.
There are very few things as satisfying as a good 1911. A good P&R S&W revolver is one, and I can't think of any others.
Of course, that is just my very biased opinion.
