Pardon the size--I only recently learned how to (sometimes) do Copy and Paste on gun websites. No idea how to create a simple thumbnail.
Found this chart by accident while searching for random 3rd Gen. images with a very typical Google search.
It's the first mention I spotted for any basic list of a given generation-never mind All three Generations.
Maybe Mods here could create this as a sticky? My only objective was to have a quick reference: possibly immed. avail. with a printed copy in the car for a random gun store discovery (a single stack might be nice) or Armslist.
