Just wondering if anyone has noticed more reported problems with the 9mm series of Steyr's, both M and S series, over their .40cal counterparts? i don't know if it's my imagination or actually true. My personal experience has bourne this out. I had an M40 with over 1400 rounds through it and never had a malfunction, not one, ever! I sold it, because I wanted to start carrying an S series. i went with a 9mm this time, in a gun that supposedly only had 32 rounds fired through it, now I know why, After shooting a couple mags thru it, it started to fail to go into battery after every shot, then locked up completely, to the point of having to disassemble the frame and slide then pushing down on the barrel hood to release the barrel fromlock up. Thought it might be the usual dirty gun/extractor, so I detail stripped and cleaned to include the extractor. Went to the range and had the same experience. Sold it to a dealer at the gun show! I'm thinking about going with either an HK P2000SK or Walther P99 compact for my next gun. I use an HK P7 normally, but want a sub compact for summer or snug clothing, but I'm not sure I want to write off the Steyr just yet. I'm thinking about finding an S40, to see what kind of luck I have with it. So I guess I'm asking if anyone has noticed this difference between the 2 calibers? My thinking is that, since the Steyr was built for the .40cal first, I'm wondering if the 9mm just doesn't have the uummpphh to cycle reliably through this platform. Eveyone's thoughts welcomed.
