Needs support. still needs expensive spring tuning kit. needs more transparency in description. - True Precision Pistol Sig P365 XL Barrel, Threaded

Fit and finish are great. The barrel is beautiful and works 100% of time if you dont attach a muzzle device.

But once you add a compensator or suppressor (even a very light one) it is likely your pistol will not cycle. At the range I had a 100% failure to extract with 4 different kinds of ammo. True Precision recommends a reduced force spring tuning kit. These kits are about $100 +/- $25. There is no guarantee they will work, and the one they recommend is not in stock.

The Optics Planet site and the product description should warn you that you still need to spend a bunch more money for it to work with a muzzle device. I would not have bought it if I had known I still needed to spend another $100ish bucks just to try to get my pistol working with a lightweight aluminum linear compensator.

If all you care about is looks and not actually adding a muzzle device, this barrel is fine. But if you actually want to add a muzzle device, get ready to spend another chunk of change and hope you can get it to work.
