I sold all of mine except a S&W Model 28-2 with 4 inch barrel and at one point I had 9 of them. I also don't like plastic pistols and my main defense pistols are all Sig's and a Sig P228 is my carry pistol. I also love the Browning HP and 1911's.
I'm one of those weird folks who shoots .357 from my .357s, I hate the cleaning the rings from the chambers. Aside from chronoing velocities for the sake of comparison between .38sp chambered gun and .357 using .38 ammo, I use .38s for shooting .38.
I have for guns in .357; a Bond Arms Derringer, Ruger LCR, SP101 and GP100 (both 3").
If revolvers are becoming more popular, it is probably because of reloading. Revolvers dont throw the brass all over. This is an important consideration today. Ammo is expensive and hard to get. Reloading is a way of getting a supply of ammo. The 357 Magnum can fire more than one type of ammo. Also a consideration. No one doubts the power of the 357 for defense. I was actually down to one gun some years ago. Kept a M19.
Is the 357 magnum becoming more popular today??
Do you mean the gun or the ammunition? Many 357 Magnum guns never see anything but 38 Special.
I recall that, a number of years ago, the 357 in a commercial 125 grain loading, was rated as the #1 man-stopper over all other handgun calibers, even bigger (41 and 44) Magnums. The thinking was that the particular bullet weight, design, frangibility and velocity, was optimal for a human target. I don't know anything about current-day ratings, or if they even exist (I suspect that law-enforcement agencies keep records) these days, but I am pretty certain that a 357 is tough to beat as a PD round.
