How Do Glock 31 and Glock 32 Compare for Concealed Carry and Duty Use?
When comparing the Glock 31 and Glock 32 for concealed carry and duty use, the key difference lies in their size and weight, which directly impacts their suitability for each purpose.
The Glock 32, with its shorter 4.0-inch barrel and lighter weight of about 23.65 oz, is more suitable for concealed carry because it’s more compact and easier to hide under clothing.

Can You Convert a Glock 23 or Glock 22 to .357 SIG Easily?
Converting your Glock 23 or Glock 22 to .357 SIG is straightforward since their frames can handle the higher pressure, mainly requiring a compatible barrel swap.
Most magazines can also be used with the new caliber if they fit properly, but double-check compatibility.
After the conversion, safety inspections are vital to guarantee reliable feeding and safe operation.
Compatibility of Frames and Parts
If you’re considering turning your Glock 22 or Glock 23 into a .357 SIG, you’ll find that the process is relatively simple thanks to their similar frame designs.
The key is ensuring frame compatibility, especially if you’re aiming to use parts like the Glock 31 or Glock 32, which are designed for .357 SIG.
To convert, you mainly need a compatible .357 SIG barrel and the right conversion parts, making sure your slide and frame can handle high-pressure rounds.
Magazines must also be compatible—Glock 31 and Glock 32 magazines are ideal for reliable feeding.
Since .357 SIG is a high-pressure round, verify that your Glock 22 or Glock 23 frame can support the increased chamber pressure before proceeding.
Proper compatibility is essential for safety and performance.
Conversion Process and Safety
Turning your Glock 22 or Glock 23 into a .357 SIG is generally straightforward, especially with the right parts and some basic tools.
The key step in the conversion involves a barrel swap—replacing the factory barrel with a dedicated .357 SIG barrel.
Most Glock frames designed for .40 S&W can handle the higher-pressure rounds, but you must verify magazine compatibility or use magazines specifically made for .357 SIG to guarantee reliable feeding.
Disassembly involves removing the slide, swapping the barrel, and reassembling, which is simple for experienced users.
Safety should be your top priority: inspect the frame’s support system, especially the three-pin setup, and check the extractor and ejector for proper function.
This process, when done correctly, enhances Glock reliability and safety with your new caliber.
