For post 357, I would like to discuss the 357sig. Specifically, why isn't it more popular? Terminal ballistics superior to the .40 IMO, but higher mag capacity than the .45. Just a simple barrel change is usually all that's needed. So why don't people jump at this? Why did most of the departments that adopted .357sig initially eventually drop it?
I know the 10mm and the stretched 9mm cases might even be better (9x23, .38super, 9x21, etc), but these generally aren't popular either. |

pita to load compared to straight wall cartridges. i think they should inherently be more reliable though, but could be mistaken |

I used to have a 357 Sig conversion barrel for one of my 40 cal Glocks.
I sold the barrel and 357 Sig reloading paraphernalia for two reasons. Reason one was that bottleneck reloading is more time consuming than straight wall and the yield is lower at Dillon speeds. Reason two was that it was just another caliber to reload and I have so many calibers to reload as it is. Other than that it's a good round. |

I've heard this. But I've never been able to load straight wall cartridges that work and never have trouble with bottleneck cartridges. I know I'm doing something wrong. As for why is it not more popular? Takes the worst aspects of .40 (reduced mag capacity, increased recoil), worst aspects of 9mm (at the time it was invented there weren't as many good projectiles), combines it with increased potential projectile setback if you re-chamber a round, and rolled it all into one. |

fact 1= 357 magnum was meant to mimic 45long colt in performance
fact 2 = both 357 mag & 45 long colt out perform 45acp. when FMJ or cast lead projectiles are used 357 sig was meant to mimic the famous remington 125 grain sjhp witch had amazing one shot stop statistics reportedly 90%+ the SJHP means scalloped jacketed hollow point unfortunately a revolver can have exposed lead at the front of a bullet while a semiauto cannot without hurting reliability . this means 357 sig cannot have the exposedlead front edge of the SJHP 
this means slower & less complete expansion in the 357 sig due to a more complete jacket. & less exposed surface area. so 357 sig has never fully lived up to the design philosophy that created it. 357 sig has proven to be a great for barrier penetration & was issued to many HWY patrol officers for that purpose. cost, recoil, muzzle blast, & the modern infatuation with smaller & smaller handguns all have made the 357sig less popular just like it made 380 more popular. with civilian shooters. Simultaneously 9mm luger has been continuously improved to the point where today it is generally accepted as a peer or even outperform 45acp. if that same technology was used to improve 45acp,10mm, or 357sig bullets things will get interesting. all of this combined gives an excellent cartridge a niche market. personally I believe 357 sig would thrive as a carbine or PDW caliber

It has the cost of the 40 (or more), capacity of the 40, recoil of the 40, but does not have the bullet mass or diameter of the 40. And everyone hates 40.
Brass and ammo is not ubiquitous. And it's more of a pain to reload because of the bottleneck. That's a lot negatives to trade off for a 9mm with a little bit more velocity. Oh yeah and 9mm bullets are designed to expand at 9mm velocity not 357 sig velocity. Pass. |
