I purchased a Stoeger M3500 this past June. I read as many reviews on this gun and others. Lots of differing opinions. Here are mine so far. I broke the gun in at a range as suggested by others, using 2.75 and 3" ammo. This is after I completely disassembled and cleaned all the factory oil from it. Worked fine at the range. September duck season opened and I've been using it ever since. Last month I used it in 20 degree F. weather. No malfunctions at all. All told I've put maybe 12 boxes of 3" Federal blue box steel waterfowl shells through it. So far I'm happy with it and would recommend anyone to give it a look if your considering a new autoloader.
