Been going back and forth on what I'm gonna do. I think I'm gonna take a chance on a 23 and 21 this weekend. I would however like to buy a non-dip extractor for each of these firearms. I know midway USA is supposed to have them, but they have a couple different extractors listed, none say "dip" or "non-dip", so how do I figure out which ones are non dip? I'm gonna need to order a .40 and .45 extractor. Thank you.
