I remember .40 S&W ammo being hard to find..could buy guns, no sweat..commercial ammo was near impossible to lay hands on...

I soon discovered a fellow who was loading the caliber and selling ammo at gunshows...I carefully reserved my commercial hollowpoints for duty use..and purchased bulk practice ammo from the garage reloader dude...his ammo wasn't cheap either..I soon quit the caliber for duty use...

Yes..I too thought the .40 would fail..and fall into obsolesence.
