I don't think we needed to re-invent the .45 ACP"
I agree. It's only purpose is to have double-stack feed and a smaller grip for shorter fingers.
I read the article that was linked here. The 37 only has a 10rd magazine. I guess that will put it ahead of single stack 45s but it doesn't compete with a Para, USP 45, or a Glock 21. I don't personally know any, but I guess some people can't wrap their fingers around the three I just mentioned. The 45GAP can at least offer them the stopping power of .45ACP and a grip they can manage better.
