The .357 Sig is NOT a necked down .40 case. If you necked down a .40 case it would be too short.
Quite right. I pulled that from somewhere else without checking it.

It's a shame that the 357 hasen't caught on more than it has seeing how it out performs the 9, .40, or .45
Well then a 9mm would be called a .355. So I think there is a reason for the different name.
Uh you got stats to back that? Depends what ammo compared to what. Many 9mm and 45 loads that blow out 357 Sig. I prefer straight 357 mag for
Thank you for that video, your test seems quite fair as well as NON-BIAS.
The 5.7 was an answer to NATO asking to replace the 9mm. At the time NATO thought of doing away with the 9m handgun and replacing it with the PDW (Personal Defense Weapon). Think something along the lines of the P90, HK MP7. Basically a firearm the size of an Uzi, MP5 but with better ballistics then the 9mm. This weapon would be for someone who's in a dangerous area but not in the front lines.I always thought the 357 Sig was a cartridge looking for a reason to exist. (same thoughts on the 5.7 and .22TCM)
I own at least six pistols in 357, so obviously I'm a fan. I bought a 357 M&P when Buds had some police trade ins. Nice gun, great shooter. I also bought a H&K USP Compact with night sights and three magazines for about $450. The same gun in 9mm would probably have been $200 more--and it probably wouldn't have been on the shelf for so long. There are some real bargains to be had on 357 guns because of perception and attitudes, and I'm fine with that.
As long as the Secret Service and Texas DPS continue to use it, fired brass will be available. I have enough JHP on my shelf to hold me over.
