The Griffin Armament ATM P365 is a complete barrel and compensator package built for accuracy and carry-ready functionality. This isn't a typical upgrade that requires gunsmithing or finesse to install. Drop the barrel into your P365 and you're done. Everything comes machined to tight tolerances and ready to go.
Griffin spent two years researching and testing to get the dimensions right on this barrel. The 416R chromium stainless steel billet is machined using 5 axis CNC with all critical dimensions locked in during a single work holding setup. This means the breech maintains perfect geometrical relationship with your slide and locking lug every time. Chambers are honed and polished smooth to feed reliably whether you're running target ammo or duty rounds. The 1:10 twist handles modern 9mm loads without issues, and the 9mm SAAMI-spec chamber works with any factory ammunition.
The included Micro Carry Comp is engineered specifically for people carrying the P365. It's cut from 17-4 stainless and finished in black nitride to resist corrosion and wear. The design redirects gas to reduce recoil and muzzle rise without printing in a holster or requiring you to change carry setups. The whole package with comp attached adds about 7/8 inch to the gun. Most users report it fits in their existing P365 holsters without modification, though some holster adjustment might be needed depending on your setup.
The 1/2×28 threading opens up options. You can run the included comp, swap it for a different muzzle device, or mount a suppressor. The target-crowned muzzle and broach-cut rifling are designed for accuracy, and the Black Nitride finish resists wear from daily use. Real-world testing shows noticeable recoil reduction with the comp, especially during rapid fire. People using this barrel report the fit is genuinely drop-in quality with no play or wobble.
Yes. Griffin spent two years testing to get the fit right. The barrel is machined to tight tolerances and drops straight in as a true replacement. No gunsmithing, no file work. It's a genuine drop-in ready upgrade.
It does provide noticeable recoil reduction, especially during rapid fire. The compensator redirects gas to manage muzzle rise. Most users report improved control and faster follow-up shots. The difference is especially noticeable with the comp versus running it without.
Most existing P365 holsters will accommodate the barrel and comp, which adds about 7/8 inch total length. Some users report fitting without any modification, while others have adjusted their holster retention slightly. It depends on your specific holster design, so test fit before carrying.
The 1/2×28 threading works with any compatible suppressor, and the precision machining ensures proper function. You can swap the included compensator for a suppressor or use a thread adapter depending on your setup.
