The Zaffiri Precision IBS complete slide is built around a simple idea: get the recoil-taming benefits of a compensated pistol without bolting a comp onto a threaded barrel. Zaffiri took their time-tested ZPS.1 slide and blended it with their Blowhole compensator, so gas gets redirected upward at the muzzle to flatten out your shots. The single-billet 17-4 stainless steel slide is machined to tight tolerances and finished in black Cerakote, with front and rear serrations for a solid grip during manipulations. It's cut for an RMR footprint and ships with a black anodized cover plate and the correct mounting screws, so it's ready for a Trijicon RMR, SRO, or Holosun 407c/507c whenever you're ready to run a dot.
Most compensated setups on a Glock require a threaded barrel and an add-on comp that can complicate holster fit. The Integrated Blowhole System skips all that by venting gas through slide cutouts that line up with the included chunk-ported barrel. You get the flatter shooting and quicker follow-up shots that come with gas management, and because it's tuned as a system, it tends to cycle reliably on stock springs. The barrel on this configuration is machined from 416R stainless steel and finished in black nitride to match the blacked-out look.
This slide is designed to drop onto a Glock 19 Gen 3 frame, and it also plays nice with the Ruger RXM and popular aftermarket frames like the SCT 19, Polymer80 PFC9, and PSA Dagger. Everything is American-made at Zaffiri's facility in Florida, and the fit and finish reflect that. This particular SKU comes with blank co-witness height sights, which is the smart move here since the heat off a ported barrel can be rough on fiber optic rods over time. A little blue Loctite on your optic screws and you're squared away.
It's worth noting the chunk-ported barrel that comes with this system is matched specifically to the IBS slide, so the porting lines up the way it's supposed to. Standard flush/crown and threaded barrels will also fit if you want to swap later.
No, and that's the whole point of the Integrated Blowhole System. It uses a chunk-ported barrel that vents gas through matched cutouts in the slide, so you get compensated, flat-shooting performance without a threaded barrel or an external comp. The barrel comes included and is tuned specifically to this slide.
It's designed to fit a Glock 19 Gen 3 frame. It's also compatible with the Ruger RXM and several popular aftermarket frames including the SCT 19, Polymer80 PFC9, and PSA Dagger. It is not designed for Gen 5 frames.
The slide is cut for the RMR footprint, so it accepts the Trijicon RMR, Trijicon SRO, and Holosun 407c/507c along with other optics sharing that pattern. It ships with the correct mounting screws and a black anodized cover plate. Use the provided screws and a dab of blue Loctite for proper retention.
Zaffiri recommends solid sights on their ported systems because the heat coming off the ported barrel can melt and loosen fiber optic rods over time. The blank co-witness height sights are sized to co-witness with a red dot. If you want a night sight, a tritium front is a solid pick here.
