Lone Wolf - Best Conversion Options **Best Conversion Options: Lone Wolf Glock Barrels** Lone Wolf has earned the reputation of being one of **the leading manufacturers** of aftermarket Glock accessories in the industry. Do you want to completely rebuild your Glock? Yeah, they can help with that. While it should come as no surprise that Lone Wolf makes their own Glock barrels as well, you might be interested to know that they don’t just produce OEM replicas. They also make completely unique barrels that stand out from their factory counterparts. Lone Wolf’s barrels ditch polygonal rifling in favor of traditional lands-and-grooves rifling. They also offer a number of barrels that convert various Glock models from one caliber to another. In addition to various threading, fluting, and color patterns, Lone Wolf also produces barrels for nearly every Glock model, including 10mm, .45 ACP, .40 S&W, and .357 Sig models. ### 4. KKM Precision - Best Precision Barrel **Best Precision Barrel: KKM Precision Glock Barrels** KKM is one of the leading manufacturers of match-grade drop-in Glock barrels. Designed for competition shooting, KKM’s barrels are a popular choice for Glock owners looking to gain a competitive edge with their accuracy. Additionally, KKM barrels are also great for shooting non-jacketed bullets as well --- perfect for anyone who has a surplus of lead ammo they’d like to get rid of. You’ll find that a large portion of the Glock owners shooting with KKM barrels belong to 3-Gun crowds. This is because KKM barrels are known to improve accuracy thanks to their button rifling, which irons the rifling pattern into the barrel rather than cuts it. That, and the fact that KKM barrels increased tightness in the chamber is said to give competitive shooters a slight advantage over OEM barrels. While the KKM barrels might be overkill for a standard home defense setup, if you’re trying to improve your accuracy in a competitive setting using high-quality loads, KKM can do wonders for your grouping. ### 5. Zev Technologies - Most Versatile **Most Versatile: Zev Technologies Glock Barrel** If you know a thing or two about modding Glocks, chances are you’re already familiar with Zev. This company makes some of the **coolest slides** and most responsive triggers for Glocks. But their barrels don’t just come in pretty colors. They're also made with match-grade steel that’s resilient and withstands excessive pressure from shooting with a suppressor. Features like the unique dimple fluting, recessed target crown, and proprietary broach-cut rifling help make these some of the nicer barrels on the market. ### 6. Killer Innovations - Best High-End **Best High-End: Killer Innovations Glock Barrel** Looking for a precise barrel? Well, Killer Innovations offers just that. Killer Innovations' claim to fame is their single-point cutting system for their rifling, which is supposed to produce more accurate and consistent rifling.

Tyrant Designs Glock Barrel - Best Threaded Option **Best Threaded Option: Tyrant Designs Glock Barrel** Tyrant makes a whole bunch of Glock accessories, including some excellent barrels. They only make Glock 19-length barrels for generations 3-5, but they have some neat features. These barrels feature symmetric fluting for heat dissipation as well as deep crowning for increased bullet stability. Threaded options use the standard 1/2-28 thread pitch pattern for common muzzle devices and suppressors. Tyrant included a 1 in 10 twist rate for the barrels as well. They are forged from 416R stainless steel, and offered in either a gold titanium nitride or a black DLC finish.
