Disclaimer/Warning from 357SIG: Pete’s 357 SIG Caliber Page

The new 357 SIG cartridge is used by Federal, State, and Local Law Enforcement Agencies, as well as Law Abiding Citizens for the purpose of Sports Competition and Self Defense.

Welcome to my 357 Sig Hobby Page. I have some of my more up-to-date articles here, some of which I have shared with other sites. I also have some pointers to some excellent external articles and sites maintained by others.

I do not claim to be an expert, although I do rely on some expert sources. My 357sig site was created to simply share testing results, and provide information from applicable sources that I’m aware of. A main purpose of my site is to show that the new 357 Sig cartridge does indeed have merit as a new modern cartridge. If you visit a 1911 site, they will rave about 1911’s. If you visit a Glock site they rave about Glocks; ditto sith SIG web sites, etc. I believe most folks understand what specialty sites are for.  That being said, enjoy.

High Quality Ammo: Bullet Setback Safety
With the correct die setup and components, such as using AA#9 powder, the 357 SIG caliber can be virtually impervious to bullet setback catastrophe, making it just as safe or even safer than other duty calibers:

357SIG Chronograph Data With Selected Powders
Subsonic refers to speed less than that of sound in air and could therefore be any velocity less than 1129 fps approximately, although, a lot of people like to think of subsonic as less than 1000 fps. Transonic refers to getting close to the speed of propagation of sound and can therefore range between 1027 fps to 1144 fps at sea level. Supersonic refers to greater than the speed of sound waves through air, approximately 1129 fps or greater.

Power Factor = velocity_fps X bullet_grains / 1000

Energy_in_ft/lbs = (the ability to do work) = velocity_fps X velocity_fps X bullet_grains / 450400

Disclaimer: Factory built 357 SIG pistols have been tested and approved by the issuing firearms companies. If an aftermarket 357 SIG barrel is available for a given pistol, you must use your common sense to find out whether the pistol can handle the 357 SIG cartridge safely and function reliably with the magazines, etc. You are responsible for your own actions.

NOTE: SIGARMS PROVIDES A FULL LINE OF 357 SIG PISTOLS (SMALL, MEDIUM, AND LARGE). This is the company that started it all. Their 357 Sig pistols are among the best with the softest felt recoil pistols on the market. If you can’t afford the Classic line, I highly recommend their polymer sigpro 2340.

NOTE: In the polymer style pistols, SA has the honor of manufacturing the longest factory 357 Sig barrel — 5″. SA PROVIDES COMPACT AND FULL SIZE PISTOLS IN THE 357 SIG CALIBER, with a subcompact 9mm on the way. Barsto.com fully supports the Springfield XD line.

Aftermarket Barrels: A Non-Exclusive List
Disclaimer: Even if a 357 SIG aftermarket barrel is available for a given pistol, you must use your common sense to find out whether the pistol can handle the 357 SIG cartridge safely and function reliably with the magazines, etc. I’ve personally only had experience with Barsto, Jarvis, KKM, and glockmeister. You are responsible for your own actions.
