Zaffiri Precision is well known for making aftermarket slides. Starting out with Glock parts and slides, they have moved into doing Sig accessories as well. This includes their Sig P320 Compact slide and barrels.

As mentioned, the Zaffiri slide I received was for the Sig P320 compact. This slide would also be great for anyone building a P320 compact off of the Sig P320 FCU. Zaffiri also sent along one of their threaded and non-threaded barrels, more later on the barrels. I was looking for a compact slide so that I could run it on the Strike Industries modular 320 chassis with some accessories that needed a compact slide. I also installed it on a standard P320 compact grip module to see how it performed as a standalone slide.

The Zaffiri ZPS.2 P320c slide is very nice. You’ll notice that the slide is lightened with, what I like to call, the Zaffiri slide cuts. These slide cuts consist of some small rectangle windows on the side and some angled smaller cuts on the top. It makes for a nice look. Then, as per any slide, there are some rear cocking serrations. A big feature about these slides is that they are cut for an RMR footprint. The slide has bosses to rest the optic on, as opposed to just screw holes. Zaffiri also supplies screws that they say to use for optic mounting. A cover plate comes installed on the slide, in case you don’t want to mount an optic.

Zaffiri Precision has 4 standard color options for the ZPS.2 P320c slides. They are: FDE, OD green, Sniper grey, and Armor black, which is the one that was sent to me. In the custom line of P320 slides you have a vast selection of colors and patterns. Camo colors only add around an extra $90, total, over the standard 4 colors. The Armor Black is beautiful, probably a testament to the applicators. It’s smooth and didn’t even chip or wear off when installing the iron sights. The top notch machining used to produce these slides, also aids in the fact that the coatings look so good.

Now let us discuss the Zaffiri Precision P320 compact 9mm barrels. Zaffiri actually sent me both a threaded and non-threaded (Flush and Crowned) barrel. The flush fit was needed for the Strike Modular Chassis, and the threaded is for future add-ons. Both came in a black nitride coating. SS, TiN, and Spectrum are also available. All the Zaffiri barrels have a swirl pattern on the outside. The threaded barrel comes with a thread protector and is threaded ½-28. Both barrels have conventional rifling and a polished chamber and bore. One can definitely tell that the bore and rifling is polished when looking through the barrels. From shooting both of these, they appear to be very accurate. Or at least better than my shooting ability.

This Zaffiri slide and both barrels performed flawlessly. Both in the Strike Chassis and in a standard grip module. The P320 slide has way more time in the Strike chassis with the standard flush fit barrel. But this doesn’t take away that it works nicely in a grip module. In the Strike chassis, I used it without a slide mounted red dot. When in the 320 grip frame, I mounted up a Swampfox Liberty green dot. The slide functioned great with or without the optic. Lock up with the barrel is super tight. Slide to frame fit is not sloppy. Essentially, in both applications, the performance was good. Plus, the slide and barrel look good, which we all know that looking good is key.

If you are in the market for some aftermarket Sig P320 stuff, Zaffiri Precision has what you need. The ZPS.2 P320c slide and barrels are really well machined and just beautiful to look at. But that’s not all, they perform well too. So if you are building out a P320 compact, or just upgrading the one you have, I would recommend that you check out the stuff from Zaffiri Precision.
