Im interested in upgrading to a 2011, (Ive been using a Glock 34). Im looking at the STI Edge .40 probably from Brazos. Will these run on factory ammo? I dont reload, but hopefully this winter I can get something done. Is there much for parts that wear out in these? How often do you need to clean them, are they pretty finicky. I see quite a few "race guns" at the range having issues. I guess Im not interested if it doesnt run 100% all the time. Also I see people at matches cleaning mags a lot and not loading mags till they get to the range. I usually load my mags a day or two before, do the springs wear out easily? Any other critisism or advise you can give would be great, Thanks
