Frequently Asked Questions

How can a Glock 27 be made more versatile?

The Glock 27, originally chambered in .40 S&W, can be made significantly more versatile by using aftermarket conversion barrels. This allows it to reliably fire other calibers such as 9mm Luger, .357 SIG, and even .22 Long Rifle, offering cost-effective training and broader defensive capabilities.

What calibers can a Glock 27 be converted to?

With the right aftermarket conversion barrels, a Glock 27 can be converted to fire 9mm Luger, .357 SIG, and .22 Long Rifle. For .357 SIG and 9mm conversions, often only the barrel needs to be changed, as the slide and many internal components are compatible.

Why is a fully supported chamber important for a Glock 27 in .40 S&W?

Factory Glock barrels in .40 S&W are not fully supported, which can be a concern with certain ammunition or when reloading. Using an aftermarket barrel with a fully supported chamber, such as those from KKM Precision or Barstow, provides enhanced safety and reliability for the .40 S&W cartridge.

What are the benefits of converting a Glock 27 to .22 Long Rifle?

Converting a Glock 27 to .22 Long Rifle using a conversion kit offers a highly economical way to train. It allows users to practice fundamental skills like drawing and shooting without the recoil or cost associated with .40 S&W, making it ideal for high-volume practice.
