The True Precision drop-in replacement barrel is an easy upgrade to your Glock 48 handgun. Machined from USA sourced certified 416R stainless steel, the True Precision barrel has proprietary broach cut six groove rifling which not only increases your accuracy potential, but also allows for the use of all types of ammunition, including cast lead. The 9mm, SAAMI spec chamber is fully supported. Added chamfers, improved radius cuts, and precise machining produce a barrel with a better than OEM fit. Additionally, this particular barrel is threaded 1/2×28 and includes a thread protector!
