Frequently Asked Questions

What are the potential issues with using lead bullets in a Glock 21 with an aftermarket barrel?

Using lead cast bullets in an aftermarket barrel like Lone Wolf can sometimes lead to failures to go into battery due to tight chamber tolerances. Additionally, factory Glock barrels with polygonal rifling are generally not recommended for unjacketed lead due to fouling concerns.

How does the stock Glock 21 compare in reliability to one with an aftermarket barrel?

The stock Glock 21 configuration, especially when paired with reliable factory FMJ ammunition like Winchester White Box, demonstrates superior reliability compared to a setup with an aftermarket barrel that might have tighter tolerances, potentially causing malfunctions.

What ammunition did Hickok45 use during his Glock 21 reliability test?

Hickok45 used both 230-grain lead cast bullets during his test with the aftermarket barrel and later switched to Winchester 'White Box' 230-grain FMJ ammunition when testing the pistol with its factory barrel.

What is polygonal rifling and why is it relevant to Glock barrels?

Polygonal rifling features smooth, angled surfaces instead of traditional sharp grooves. While durable and accurate, it can be more prone to fouling when using unjacketed lead bullets, which is why aftermarket barrels are sometimes preferred for such ammunition.
