Zev Hellbender Z17 & Z19 Slides

Zev, the Washington-state-based manufacturer of aftermarket parts, accessories, and complete weapons, has updated its offerings for Glock and OZ9 slides to include the updated Hellbender slide. The Hellbender slide is compatible with Gen 3 and Gen 5 Glock 17 and Glock 19 pistols as well as Zev’s own OZ9 pistols.

The Hellbender sports coffin-shaped cuts on the top of the slide and three side windows per side. The cuts are there to help cut down on the overall weight of the slide and help reduce the recoil impulse of the pistol. The Hellbender is manufactured from single billet 17-4 stainless steel to incredibly tight tolerances that factory slides. Zev states that this increases consistency in barrel lockup for improved performance and accuracy of the weapon.

Additionally, the Hellbender features deep serrations on both the rear and the front of the slide. This creates a more aggressive grip for betting handling and manipulations of the slide. The Hellbender gives durability and accuracy when it matters most, according to Zev.

Like all other Zev slides, the Hellbender has the patented optic cut with threaded mounting posts machined in the slide for a more stable and secure optic mounting platform. Since the optic cuts are so deep, it allows the red dot sight to sit lower in the slide making it so the shooter is able to co-witness with even standard iron sights.

Zev Hellbender slides have DCL or PVD coatings that have a Rockwell hardness rating above that of factory slides, according to Zev. Also, using a Hellbender slide will reduce the reciprocating weight, reduce shooter fatigue, and increase the speed of follow-up shots. This is thanks to it weighing less than factory slides, with the Z17 weighing 9.3 ounces and the Z19 weighing 8.2 ounces.

The RMR plate is included from Zev for the Hellbender and the slides are available in black or gray for all models. The Zev Hellbender Z17 and Z19 have a price tag of $455.
