The .45 ACP has never been more alive and well in the civilian market, but the .357 Mag is on the way out. Defensive revolvers themselves are on the way out, and the .357 Mag has been no closer than 4th place amongst handgun hunters for decades.
Were are you getting this stat? The .357 is not going anywhere IMO although good ammo can be hard to come by some times.
Start a thread asking for advice on a hunting cartridge and see how the .357 Mag fares.
I agree, the .357 Mag isn't going anywhere, but its popularity peaked around 1970, crashed during the '80's, and has become a niche cartridge. Kinda like the 10mm.
