Glaser Glaser Blue .357 Mag

A: Hi Dwayne Charles and welcome to Bud's. The answer is no, they are 2 completely different calibers. Since the case diameter of a .357 Magnum is .379″, and the base diameter of .357 SiG is .425″ you will find that .357 SiG won't fit in your revolver. If you could somehow pull that off, it would be unsafe to shoot. You would have likely damaged your revolver in the attempt. Stay safe & have a great day!

A: Hi Dwayne. Unfortunately no. .357 Sig is a rimless Semi-Auto cartridge and .357.38 Spec are rimmed cartridges. Differences shown here (.357 Sig on left and .357 Mag on right): https://www.ssusa.org/content/357-sig-vs-357-magnum-which-is-more-powerful/#:~:text=357%20Magnum%20wins%2C%20because%20full,Comparing%20full%20power%20.

A: Dwayne, no, they're two completely different calibers and wouldn't recommend trying it. While the 357 sig was designed to mimic the 357 mags power it's a rimless cartridge designed to be used in semi automatic pistols. The 357 mag is rimmed. Now you can fire 38 special in any 357 Magnum revolver. Sorry but hope this helps.
