Around where I live, I can't find many 9mm pistols in stock, but if you want a .40, dealers have plenty.
And two distinct advantages offset those: superior barrier penetration to either the 9mm or .45, especially auto glass, and being able to fit in a 9mm-sized frame so it can fit shooters who can't handle the girth of a .45
The recoil of the .40 is very exaggerated IMO. I started shooting it regularly, and well, around when I turned ten. The 155s are a bit snarly, but the 180s - which I prefer anyway - are not bad at all.
