Product Overview
Product Description
Griffin ATM™ (Advanced Threaded Match) Barrels are billet machined from 416R chromium stainless steel to exacting tolerances for drop-in match performance. Five-axis machining in a single work-holding operation positions all critical dimensions on the breech, ensuring an optimal geometric relationship between the barrel, slide, and locking lug. Chambers are honed and polished to provide a smooth surface finish and reliable function across a wide range of ammunition, from training to duty use. Extensive research and testing informed the final barrel dimensions, resulting in precise fitment that enhances accuracy without compromising factory reliability. Designed with concealed carry users in mind, the barrel provides accessory and suppressor support while maintaining dependable performance.
For a limited time, the barrel includes the patent-pending Micro Carry Comp, adding both value and performance. The Micro Carry Comp (MC²) is designed to maintain a low signature for concealed carry, fit a wide range of holsters without modification, and reduce recoil for faster, more accurate follow-up shots and improved control. Its compact and lightweight design minimizes any impact on firearm handling and storage.
