Frequently Asked Questions
Will this barrel fit my Glock 19 Gen 5?
The True Precision threaded barrel for the Glock 19 is designed primarily for Gen 3 and Gen 4 frames. Gen 5 models feature a different barrel profile and chamber geometry, so fitment is not guaranteed. If you own a Gen 5 Glock 19, we recommend confirming compatibility with True Precision or contacting our team at Goodland Guns before purchasing.
Can I use standard (non-jacketed) lead ammunition with this barrel?
True Precision barrels use a traditional broach-cut rifling profile, which is generally compatible with a wider range of ammunition types compared to the polygonal rifling found in factory Glock barrels. However, always consult the ammunition manufacturer's recommendations and inspect your barrel regularly for leading if using cast or lead bullets.
What suppressor or muzzle device thread protector do I need?
This barrel is threaded at 1/2×28 TPI, the most common thread pitch for 9mm suppressors and muzzle devices in the United States. A thread protector in the same pitch should be used whenever a suppressor or muzzle device is not attached, to protect the threads from damage. Many suppressors in this caliber will attach directly without an adapter — verify your specific suppressor's thread pitch before purchasing.
