Frequently Asked Questions
Will this barrel fit my Glock 19 Gen 5?
This True Precision threaded barrel is designed for Glock 19 Gen 1 through Gen 4 frames. Gen 5 Glock 19 pistols have a slightly different barrel lug and chamber geometry. If you have a Gen 5, confirm compatibility with True Precision or look for their Gen 5-specific variant before purchasing.
What thread protector or suppressor can I use with this barrel?
The muzzle is threaded at the industry-standard 1/2×28 TPI, making it compatible with the vast majority of 9mm suppressors, muzzle brakes, and compensators on the market. A thread protector is recommended whenever shooting without a muzzle device to protect the threads from damage.
Does the Black DLC finish affect durability compared to standard barrels?
Yes — Diamond-Like Carbon (DLC) coating is significantly harder and more wear-resistant than traditional phosphate or nitride finishes commonly found on stock Glock barrels. DLC reduces friction during the feed cycle, resists corrosion from sweat and moisture, and maintains its appearance even after heavy round counts, making it an excellent long-term investment for a carry or duty pistol.
