What is the Strike Modular Chassis (SMC) - BRAVO?

The Bravo is a chassis system for the SIG Sauer P320 by Strike Industries that boasts that it is the new lite version of the MOST MODULAR P320 (SMC Alpha) Chassis in the WORLD at a fraction of the Alpha's price. Customer feedback was heavily weighed and taken into consideration when we developed this chassis so when we say the Bravo was made with the user in mind, we mean it.

The new SMC Bravo is made of Polymer Extreme™ which is durable and lightweight — intended to receive P320 FCU's and slides to complete the entire ensemble. This time around users can fully utilize their P320 optics-ready slides to effortlessly install their red dot sights! In terms of upgraded features in the Bravo, the ergonomics have improved with a textured grip which now includes a built-in flared magwell to assist with quick and smooth reloads.

Every compensator we manufacture has undergone rigorous reliability testing!

The design phase

Every product we make goes through a week long design process and multiple versions before we machine a prototype!

CNC Machining

We currently machine all of our compensators on 2 brand new Doosan DNM4500S CNC milling machines and a 2019 Tormach 1000mx CNC milling machine!


The answer is easy! All you need to do is purchase the threaded barrel that matches your slide. For example, if you have a carry length slide you need a carry length threaded barrel (4.6"). If you have an X compact slide you need a X compact threaded barrel (4.3"). This will allow you to run a longer frame and give you an integrated look.


Yes they do. We have run tens of thousand of rounds through all of our models and have had zero malfunctions. If you are having an issue with a build, it is likely the case you have installed our prodcut incoretly or your handgun needs broken in. Compensators need a smooth running system to be reliable. A new handgun has tolerances that need to be worn in before we suggest adding a compensator

-It's easy! We designed our comps to be self-timing so all you have to do is

- Remove your slide from you frame

- Remove your guide rod assembly

- Apply Loctite to barrel threads

- Thread comp onto barrel until it stops

- Back off a 1/8 turn

- Apply Loctite to set screws

- Tighten down set screws
