I was one of the very first in the US to use and RELOAD the 357SIG and I finally ditched it a few years back. The cartridge design doesn’t allow for a proper neck, so bullets experience setback during chambering. I had a factory Federal round fall back into the case and detonate the grips and extractor on my SIG P229 back in 1994. I don’t think ammo manufacturers were ever able to properly solve the problem. That, and it was a pain in the ass to resize and reload.
Stick with 9mm, .40SW and .45ACP and you’ll be fine.
I recall looking at a .357 Sig at a gun shop and thinking it was an odd little number. I couldn’t figure out the attraction of this new round, unlike the .40 S&W which has been very successful.
