Hello everyone. Just a little background for my question: I have just joined, after lurking on the forums for a while. I have read several posts on failures to eject a spent cartridge from the Steyr S9-A1, and the recommendation to install a 1911 spring. I need some advice as to whether I really have a problem yet or not. Here's what's been happening. I bought my Steyr S9-A1 in June this year. It was manufactured in November 2014 and has the roll pin under the rear sights. So far I have fired 549 rounds of 115 grain Sellier & Bellot FMJ through it. The first 20 rounds never suffer any problems. Thereafter, I normally suffer an average of one failure to eject properly every 20 rounds. Is this just the kind of thing I can shoot out? Are the springs still stiff and I just need to be patient? I have read that a Steyr's tolerances are closer than a Glock's and that it needs a longer "shooting in" phase. But I did not think I would have problems beyond 500 rounds. The last time I fired 50 rounds, I suffered two failures. So basically, my question is: what are odds that another 50-100 rounds will sort this problem out? Because I live in South Africa, gun parts are not at all easy to acquire, so the 1911 spring option will not do. The suppliers from whom I bought the pistol are willing to take it in, but I wanted to ask advice here first. Any thoughts? Thanks in advance.
