40 S&W going the way of the wild goose?

[AtlLaw]

I was looking at reviews of a pistol I thought may be a good EDC.  Don't ask me what it was, old age faulty memory and all that...    But I do believe it was a police trade-in.

Anyway it was a 40 S&W caliber handgun; a cartridge I have no experience with.  In the PD I carried a S&W M10 in 38 Spl. for most of my career. And those had to be loaded with 158 gr. RN factory ammo.  So even though I heard the .40 S&W termed the "40 short and weak," I figured it had to be better then the 38 Spl.!  And also  bigger and better then the 9mm auto's we went to just before I retired. Once retired and given a choice of what to carry I went to a 45 ACP S&W Shield. 

But this author indicated that the 40 S&W has fallen out of favor and is on it's way to obscurity!  I think he said something about this being due to the advances in 9mm ammunition.

Now I don't take gun writer's words as Gospel but it got me thinking.  Has anyone seen any indication of the 40's decline in popularity?

I have, in both civilian and law enforcement use.  Many LEAs have been dropping the .40S&W for years and going to the 9mm.  And during the last ammo shortage, .40 ammo was hard to find at any price. 

But there are still plenty of folks who prefer it, so I don't think we're ready to read its eulogy just yet.
