Frequently Asked Questions
Is the .357 SIG round hard to find or expensive?
While not as common as 9mm, .357 SIG is a dedicated defensive round from major manufacturers. It is typically priced as a premium cartridge, reflecting its performance. Availability is stable for those who plan their training and carry ammo.
I’ve heard the slide can be hard to rack. Is that true?
The .357 SIG operates at higher pressures, which can result in a stiffer recoil spring. This contributes to the slide feeling “tight,” which is a design feature for reliability. One customer returned a G33 citing this, but we confirmed it functioned flawlessly on an OEM frame—the issue was an incompatible aftermarket part.
Can I convert this to shoot .40 S&W?
Yes. The G33 can be converted to .40 S&W with a simple barrel swap, as the two cartridges share the same case head diameter. This is a popular option for more affordable training. Always ensure you use G33 or G27 magazines for reliable feeding with either caliber.
