I have owned and shot 1911's for years, and have not had the problems that most of you seem to have had. Perhaps, I have been blessed by the angel John Moses Browning. Most likely, I buy only those 1911's, which are made properly. I currently own nine 1911's, and they range from a Norinco to an Ed Brown Target. I have had problems with one of my 1911's, and that was an easy fix...an extractor.
I continually hear and read about the maintenance that needs to be performed on these handguns, and I just don't see it. I change out a recoil and firing pin spring peridocally, and I'm set. An extractor will go 30K, if it's any kind of extractor at all.
I have liked HK's since I bought my first P7M8. There was nothing like it. I bought two more, then I bought my favorite HK, an HK45. It is flawless in design and on the range. There are two autos I would put next to my bed. One is a 1911, and the other is an HK45.
Two months ago, I purchased two handguns. One was a Colt XSE, the other was an HK P30. Both have about 1,500 rounds through them as of this date. The P30 had at least 10 FTE for every box I shot for the first six hundred rounds. Now, it is malfunction free. My XSE has had one FTF. The round was an aluminum cased Blaser, which had a dent in its middle. It just wouldn't chamber. Imagine that.
Last week, I obtained a USB Elite in 9mm. What an accurate 9mm, it is a spectacular shooter. For the first 100 rounds or so, it would occassionally fail-to-return-to-battery. It just wouldn't go past that O-ring. I shot it Friday, Saturday, and Sunday. Brass hits me on the head almost every shot, and I had a few FTE's. And this is a $1300 gun.
One of my M8's was so sluggish with the slide return that I had to send it back to the factory. It seems it came with a dented gas cylinder.
What's my take on this? Crap happens, and HK still makes a great handgun. While there are many ways to reduce problems by purchase choices, you can't eliminate them. HK still makes a great gun.
The design, not the manufacturers of the 1911 is solid. It is heavy, but I don't have to carry it on force marches, It is SAO, which cause me no grief, and it has a capicity lower than double stacks. I can stack 9 rounds in any of my 1911's, and that's only 2 less than an HK45. I can live with that too.
