Speer Lawman 125 Grain Total Metal Jacket .357 Sig

A: 357 sig and 357 magnum are two completely different rounds. 357 sig was created to replicate the 357 magnum but be reliable in a semiautomatic. They did this by knecking down a 10mm round and adding a 9mm diameter projectile. So yes 357 sig won't work in a 357 mag. There's alot of firearms made for 357 sig like Glocks, sig saurs, and S&W. So look at it this way, now you have a reason to buy another firearm, lol.

A: Its rimless and made for semi autos Developed in 1994, the new cartridge was named "357" to highlight its purpose: to duplicate the performance of 125-grain (8.1 g) .357 Magnum loads fired from 4-inch (100 mm)-barreled revolvers, in a cartridge designed to be used in a semi-automatic pistol with greater ammunition capacity than a revolver. Performance is similar to the 9×23mm Winchester.

A: The.357 SIG is a bottlenecked rimless centerfire handgun cartridge developed by the Swiss-German firearms manufacturer SIG Sauer, in cooperation with ammunition manufacturer Federal Cartridge Co.. The cartridge is used by a number of law enforcement agencies and has a good reputation for accuracy. Sounds like you need a new gun to go with that ammo.

A: Raymond, unfortunately, you purchased the Semi-Auto .357Sig ammunition instead of .357 Magnum ammunition. They are totally different and not interchangeable as pictured here : https://www.flickr.com/photos/itwuzcryptic/2318885470

A: Yes they will Robert

A: Robert, no Sir. This is an entirely different Semi-Auto load from a 357 Magnum and is not interchangeable. Visual difference here : https://www.quora.com/What-is-the-difference-between-a-357-and-a-357-magnum

A: No this is designed for semi-auto handguns like the Glock 31, glock 32, or glock 33. It is used by state police all over the USA, it is designed to be harder hitting with better barrier penetration , and is basically 40sw case necked down to a 9mm projectile, so you get a larger powder load and a smaller bullet which equates to a much faster bullet. But it will not fit in a 357 magnum.

A: Buds is out of 357 Magnum ammo right now. In stock here though https://www.ammobuy.com/ammo/357-mag

A: No, They definitely will not. 357 magnum and 357 sig are two completely different rounds. Hope this helps.

A: No, 357 sig will not even fit into a 357 mag. 357 sig is a round typically used in autoloaders and fires a similar projectile at similar velocities, but the cartridge design is completely different. The only other ammo a .357 mag will take (with some exceptions) is .38 special. This is because .38 special is the same diameter just slightly shorter and less powerful. I hope this helps.
