I think 45 is mostly dying in traditional new guns but has found its place in specific weapons like the 1911 and other metal frame platforms as a smooth shooting heavy round. It definitely has its place.
That's what I'm saying. You can count on 9, 40, and 45 to be around for a long time. Saying any of these three are dying is simply untrue. 9 is winning the popular vote, right now, but they sell a lot of all 3 still
