It depends on the load.
Depends on the load and the powder used.
The ammunition is called .357 Sig. Most pistols in .357 Sig can shoot the .40 S&W when you drop in a .40 S&W barrel.
Most newer generation Glocks can shoot the .357sig in a .40S&W with a simple barrel change. You can use the same magazines. The same is true for shooting .40 in a .357 Sig. This is true with Sig Sauer guns as well. I have a Glock 23 (.40 S&W). I simple install the Glock 32 barrel (.357 Sig) which I purchased for $100. I can shoot .357 sig out of the same gun. The magazines (at least for Glock) for the .40 and .357 sig are interchangeable. You CANNOT safely shoot a .40 out of a .357 sig barrel or vice versa. A barrel swap is required. If you load a .357 Sig round into a barrel chambered in .40 S&W, it could fire, but it would probably cause damage to the gun and won't be accurate. .357 Sig has better "terminal performance" than the .40, but the .40 shells cost less which translates into more practice for the same $$$ with the .40, and better self defense with the .357.
Yes, you can fire a .357 Sig round (not a .357 Magnum) in it, but you must first change out the .40 barrel for the .357 barrel.
Yes and no. The. 40 S&W is not interchangeable with the .357 Magnum, if that's what you had in mind. Most .357 Sig pistols can, however, but a .40 barrel will have to be dropped in in place of the .357 Sig barrel.
The clip will work for either .40 or .357 sig
The answer is yes....and no. By performing a barrel swap to the 357 sig barrel the gun is capable of shooting the 357 sig round. However, the 357 sig has a much higher barrel pressure (5000-10000 more psi). While the gun can shoot the 357 sig round simply by changing the barrel, this will cause more wear than is normal and can possible damage the slide. The safe bet is to buy a slide and barrel meant for the 357 sig round.
Yes. The barrel has to be replaced with the .357 sig barrel, but the magazines are the same.
both good
No.
The .357 Sig is a 9mm projectile, loaded into a necked down .40 S&W casing.
No. The 357 SIG magazine will not fit in a 40 caliber Glock such as the model 22.
