Hi Victor, no sir, this is for 9mm only. Although similar in size, 357 Sig & 9mm are not interchangeable.
Stay safe & have a great day!

Hi Victor and welcome. Unfortunately, no Sir. .357 Sig is a bottle neck cartridge (40S&W necked down to 9mm). It will not chamber in this 9mm firearm. 3rd picture down: guns.com/news/reviews/57-vs-357-sig-bottleneck-cartridge-battle

no it is a 9mm only 9mm goes by several names 9mm Luger, 9mm Parabellum, 9x19 are all the same 9mm Nato is fine in most guns it is just slightly hotter and 9mm+p is a littler hotter than
9mm nato and should only be used in guns rated for it 9mm+p+ is not sami rated and should not be used in most 9mm guns
