Strike Industries SMC Bravo

Chassis Review

Today, we're taking a look at the Strike Industries Bravo Chassis designed for the Sig Sauer P320. I received this chassis from Strike Industries, and since I had a P320 Compact sitting around, unused—not due to reliability issues, but simply because I didn't like how it felt or shot. I decided to reach out to Strike Industries for a chassis to create an interesting range toy.

Upon receiving the Bravo chassis, I realized I needed a few additional parts to complete the build. So I headed back to Strike Industries to purchase their pistol brace, compensator, and blast shield. I also contacted the team at XS Sights for a set of tall tritium suppressor sights that illuminate brightly. Now, back to the chassis itself, everything necessary to complete the build was included in the box. Including the chassis and a new back plate with a charging handle for easier operation.

I opted for the FDE version of the chassis and mixed in some black components to enhance its appearance. The SMC Bravo stands for Strike Modular Chassis, and it's a lighter alternative to the Alpha system. Made from Polymer Extreme, it’s both durable and lightweight. This chassis is designed to accommodate the fire control unit and offers ample rail space for accessories. From the grip upwards, it features a flared mag well for smoother reloads. The frame includes a built-in gas pedal for improved stability, quicker follow-up shots, and better control. The rear back strap is integrated with a 1913 rail for attaching your preferred brace. Additionally, there's a molded QD socket for a quick-detachable sling system, making this chassis a versatile platform for a PDW, SBR, or any creative setup you envision.

I added a spare magazine holder to the front, which provides quick access to an extra magazine and offers a place to index your hand. The takedown lever is a standard OEM part, and installing the trigger package was straightforward, as it is designed to accommodate both OEM and aftermarket trigger units. The Strike Bravo chassis is compatible with all P320 slides, but if you plan to use a shorter compact slide, a threaded barrel and compensator will be necessary to manage the muzzle blast. You can utilize P320 17-round, 21-round, or larger magazines. While it’s claimed that the chassis fits a variety of holsters, I've chosen to carry mine in a sling bag without a round in the chamber, as I find it would be too bulky in a holster.

At the range it was a pleasure to shoot. It was great having a third point of contact to stabilize the pistol. I was able to easily hit targets at 50 yards with iron sights. I had no issues with the reliability of the system. Everything on the system was either Strike Industries or OEM Sig parts.

As with Strike Industries and their website, there is very little technical information or specs on the product. I would like for Strike Industries to add size and width, blah blah, to the product specs. Overall I like their system. I don’t think it is a viable option to a traditional pistol when being worn in a holster. I do think it is a viable option of being a truck gun, backpack, or sling bag firearm. Home defense would be a plus as well. Their Bravo chassis opens itself up to give you a platform to go from mild to wild. I think it was clearly made well, the price for the chassis is on point, but to add all the other accessories, it gets a bit pricey.

After using the Strike Industries Strike Modular Chassis for the Sig P320, I am finally letting you know my thoughts. The Strike Modular Chassis - Alpha series, or SMC for short, is made to drop in your Sig P320 fire control unit and slide. This gives you a more controllable platform with a bunch of different accessory options.

In the box with the Alpha series Strike Modular Chassis are a bunch of other accessories. You may or may not choose to use them, but they are there. Of course there is the Alpha series SMC. But along with the SMC is an optics platform, a side charger adapter, a set of gray grip panels, and an angled front grip that also will hold an extra magazine. Various screws and allen wrenches are also included to install all that stuff. There are also some added bonuses. Like a mini figure SMC for those brick toys, a SMC patch, and a SMC pin. Those little add-ins are pretty cool.

I’ll try to explain the SMC to you, but the pictures may explain it better. It is machined from 6061-T6 aluminum, so it’s not your Grandma's plastic grip. As it sits, it looks like a pistol frame with an extension running off of the back. The extension has some QD’s on it, along with a vertical picatinny rail for attaching stuff, like a pistol brace, when they become legal again. Along this extension is also where the raised optic platform mounts. Up front is a standard picatinny rail section for attaching lights or the supplied angled foregrip/extra magazine holder. Oddly enough, there is also a hole through the front pic rail which is used to mount compensators, more on that later.

At first, I dropped my P320 FCU and a full length 4.7” slide into the Strike Modular Chassis. The FCU slid in pretty easily, but still fit snug. This slide had an optic already mounted to it, so I left it for the time being. I also installed the charging handle on the rear of the slide. One basically swaps out the backplate and then screws the charging handle on, on whatever side you want to use it on. Strike Industries also sent me their Dual Folding adapter, or folding brace. So I installed this on the rear pic rail. This was before using a brace was a problem. I also installed the foregrip. I shot it a while in this configuration. I might mention that where the rear pic rail is on the SMC, it has a “U” shaped cut-out, so you can see your iron sights or slide mounted red dot easier. While using this config, I did notice that the changing handle rubbed a little bit on the side of my optic. The charging handle moves with the slide, so it doesn't rub along the optic, it just rested up against it, causing the vibration of the firearm to rub a little wear mark in the side of the optic. The charging handle really did make it easy to cycle the slide, I can see why Strike Industries now offers it as a stand alone product. Other than the rub mark, I was pleased with how the SMC was working.

After a bit, Strike Industries sent out some more accessories to attach to the SMC. They sent the Magwell, Blast Shield, and 2 compensators. I immediately installed the Magwell as it makes reloads easier. I also installed the Blast Shield. The blast shield mounts up on the front pic rail. It gives the slide some “shields” to keep muzzle blast at bay. It also protects your hands when using one of the compensators. The Blast Shield has a lower pic rail also, so rail attachments can still be used, they just sit slightly lower on the firearms frame. I couldn’t immediately install the comps, because I needed a carry length slide with the 3.9” barrel. Zaffiri Precision was kind enough to help me out with one so that I could use the compensators.

The compensators come in two sizes, a Small and Large. The Large one has more mass and more ports, but it also is longer so it sticks out past the blast shield or dust cover. The Small comp is flush with the blast shield and barely sticks out past the pistols dust cover. Both of these comps are for non-threaded barrels only. This makes the comps 50 state legal. The comps come with a screw to mount them. They mount through the SMC’s dust cover in that previously mentioned hole. Just slide the comp into the SMC and tighten the screw. These comps will only work with the SMC and a 3.9” slide/barrel. I tried out both the comps and really liked them. The Large version seemed to reduce recoil and muzzle rise better than the Small one. But don’t get me wrong, the Small comp still did an excellent job, the Large one just worked a bit better. I would choose the Zaffiri compact slide and Small comp combo when the SMC is configured as just a stand alone pistol.

The Strike Industries SMC doesn’t come without problems. Since the SMC is a modular style chassis, it screws together in places. Mainly where the backstrap slides in. At the top, there are 2 tiny screws to hold it in place. These 2 screws loosen up and can strip the frame holes out. Strike industries now says to use “red” loctite 272 on these. They still loosened up on me and one of the screw holes completely stripped out. Luckily it was on the side where a longer screw can go. So I put a screw with a nut on it and it works fine now. Once I figure out which backstrap I want to permanently use, I will be doing something semi-permanent. So if you get one of the SMC’s, use a red threadlocker on these screws and check the tightness of them after every use. The backstrap, where the web of your hand meets it, is flat. This flat makes the pistol rub your hand a bit. If Strike Industries were to round this out, the SMC would be way more comfortable in your hand, especially after a day of hard use.

When I switched to the compact slide and compensator, I also started using the raised optics mount. The raised optic mount has mounting holes for just about any mini or micro pistol red dot, like an RMR, Shield, etc. The red dot mounting seems pretty high when you look at it, but when you are using it, it works well and doesn’t seem too tall. I really like how it has the ability to mount just about any optic.

The Strike Modular Chassis is a unique addition to your Sig P320. It gives you abilities that the stock P320’s don't. The fixed, non reciprocating optic mount works well. The compensator options are great. Having an angled front grip that houses an extra magazine is very useful, especially since you can put a 30 rounder in it. The screws that strip out are a big downer for me. But as a whole, the Strike Modular Chassis is a fun and useful addition to a Sig P320.
