The Killer Innovations Velocity outperforms other Sig Sauer P320 Compensators by featuring a robust mounting system. It goes beyond merely applying barrel thread torque with set screws.

It looks fantastic on the P320, the fixed screws are excellent, and it ensures a proper fit to achieve that sleek compensator appearance on the slide. I encountered no problems with the product, and I highly recommend it if you're aiming to enhance the aesthetics of your build.

It enhances your shooting experience with faster red dot sight picture, reducing muzzle rise for quicker red dot reacquisition, faster follow-up shots, and improved recoil control.

Achieving Improved Accuracy, it maintains an even air gap, resulting in greater bullet precision and reduced vertical and horizontal recoil.

Installation is a breeze - simply tighten the locking ring. Note that set screws still require a tool for tightening.

For convenience, it offers a Fast Detach feature, allowing for easy removal during concealed carry and quick reattachment when needed.

You should be able to securely attach the Killer Innovations Sig P320 Compensator to your Sig P320 4.3 threaded barrel using the provided lock system. However, it's advisable to use the included blue loctite during installation for added security.
