Didn't read anything about a mag spring ???
Where did you find that statement , I couldn't find it in the article, only about the ejector spring.
Help me out here my eyes ain't that great.
Is this what you're referring too.
Bad ejection mechanism: Either the return spring of the slide may be too strong or the ejector spring that ejects the old cartridge is too weak. In either case, the slide moves back and then gets pushed forward and starts to close before the old case is ejected. Therefore, the old case gets caught before it has a chance to fully leave the firearm.
Well it's as you say now but what I posted was a direct copy/paste from the original article. I fear that demons have been at work.
But in any case the "ejector" does not have a spring, there may be exceptions but I am unaware of them. The "ejector" is a fixed piece of metal that serves to eject the empty casing from the pistol. What he should be refering to is the "extractor" spring on some pistols. Or as in the original 1911 design the "extractor" has no spring as it is a controlled round type of feed. If the "stove pipe" is caused by a mechanical malfunction it is more often related to diminished slide velocity which can be caused by several things. Or, possibly defective/worn "extractor".
Other causes of the classic "stove pipe" are generally related to factors other than mechanical problems with the pistol itself. Such as; operator technique, ammunition, or firearm cleanliness.
I haven't, personally, seen a stovepipe stoppage in more than 30 years because I now shoot nothing but factory ammo. Back then, I had a Colt Gold Cup with two different sets of recoil springs - heavy and light. When I was shooting light target loads, I used the light springs. When I was shooting hardball or hollow points, I used the heavy (double) spring. I had my own reloading bench, and I used to cast my own 190gr. SWC bullets for target shooting. Once, I forgot to change the spring before going to the range to shoot target loads, and I saw a whole bunch of stovepipes.
