Pros:
- High capacity
- Rugged and reliable

Cast Bullet Use:
Glock barrels have polygonal rifling, which is not ideal for traditional uncoated cast bullets due to potential leading. If using hard cast rounds that are not powder-coated, an aftermarket barrel with standard rifling is strongly recommended.
Best For:
Hikers who want maximum firepower and the rugged simplicity of the Glock platform.
