GABM,
As to your question regarding expected reliability vs. number of rounds fired, I can only tell you from my experience that it depends greatly on the gun. I have a Springfield that I had custom built almost 20 years ago and literally have roughly 10,000 rounds through (my former IPSC gun). It is well broken in and still shoots great whether it is the first magazine through the gun after cleaning or the 50th. It seems (with my guns at least) that lubed is more important than clean. All of mine will shoot dirty, but few of them will shoot dry with any reliability.
I have a Stainless Sig GSR that was one of the first hand built guns to leave Sig when they first started the line and when I got it it was so tight that it took several range trips and several cleaning/lubes to get it to shoot a box of ammo without a hic-up. Now that it's broken in, it hasn't failed on me, but because it is as tight as it is, I have a tendancy to clean it more often than some of my other 1911's.
My Kimbers have all been pretty reliable, even when dirty. I have a Brolin Arms 'Pro-comp' (built in compensator on the end of the muzzle that is profiled and cut to match the same profile as a standard 5 in 1911) that I have put over 800 rounds though in one weekend and never cleaned it/broke it down. I just lubed it with the slide locked to the rear and it kept shooting.
I have a Wilson .22 coversion kit that will fit on most of my 1911's (I really only use it on the Brolin Arms and the Springfield) and it is probably the most sensitive to dirt, but I attribute that to the fact that it is straight recoil operated and .22 ammo is so dirty/fouling that it builds up dirt/gunk much faster than any of them when they are shooting .45 ACP.
My advise to all 1911 shooters as far as reliability goes is not to skimp in the area of magazines and maintenance (spring replacement). I will only carry Wilson Combat magazines for defensive carry. I use factory or Chip McCormic mags for range/training, but when my ass is on the line with a 1911 I will only use WC mags. I have never had a malfunction that was mag related when using the WC mags. Any knowledgale pistol shooter will tell you that a vast majority of malfunctions can be traced back to bad magazines (Spring fatigue, feed lips bent/broken, dirty followers, etc.) I also replace my recoil springs roughly every3 thousand rounds. I usually use Wolff springs that are set at the factory weight or are 'tuned' to the perticular gun/load I shoot through it. (my competition guns get lighter springs as I shoot lighter loads through them.)
At any rate, once you get your gun back, I am sure they will have addressed the ejection problem. At that point, get a couple of good magazines and put about 200 rounds through it to break it in before you get to excited about cleaning it (just make sure the slide rails, barrel lugs and barrel bushing have a light coat of oil).
