Complete Slide Parts Kits: Everything You Need in One Box

The fastest way to upgrade or rebuild your slide is with a complete slide parts kit. We offer premium kits for the Glock 17 Gen 1-3, Glock 19 Gen 1-3, and Glock 26 Gen 1-3. These kits come loaded with everything needed to fully equip a slide:

• 17-4 stainless steel billet firing pin
• Firing pin spring cups (x2)
• Recoil spring assembly
• Spring-loaded bearing
• Slide cover plate
• Firing pin safety and spring
• Channel liner
• Extractor with loaded chamber indicator

Each of these kits is built by Havatek and uses a billet firing pin instead of the MIM (metal injection molded) parts found in many factory setups. Billet machined components hold tighter tolerances, which means smoother cycling and more reliable ignition over time. Pair a parts kit with one of our complete slide assemblies for a full upper build.

Lower Parts Kits for Glock 17 and 19 Gen 1-3 Frames

While the slide kits handle your upper assembly, the lower parts kit takes care of everything inside the frame. The SCT Manufacturing lower parts kit for Glock 17 and 19 Gen 1-3 includes an upgraded set of components that outperform standard factory parts. This kit works especially well for P80 builds or Geisler frame builds where you're starting from scratch.

The kit covers all the essentials - trigger housing, slide stop lever, magazine catch, and connector - so you're not hunting down individual pieces from multiple sources. For anyone putting together a custom pistol or refreshing a worn frame, this lower kit saves time and gives you better parts than what typically ships from the factory.

Recoil Spring Assemblies: A Simple Upgrade With Real Impact

Over time, springs wear down and cycling becomes less consistent. We carry OEM factory recoil spring assemblies for both the Glock 17 Gen 1-3 and the Glock 26 Gen 1-3, made to the exact same tolerances as the originals. Each assembly also crosses over to additional models in the same frame family:

• The Glock 17 recoil spring assembly fits models 22, 31, and 37 in Gen 1-3
• The Glock 26 recoil spring assembly fits models 27, 33, and 39

Replacing your recoil spring is one of the easiest upgrades you can do at home with no special tools, and keeping a spare on hand is a smart move for any serious shooter.

Firing Pins: Upgrade Your Ignition System

Desert Cat also carries a standalone billet firing pin compatible with the Glock 17, Glock 19, and Glock 26, machined from a single block of high-grade steel rather than cast or pressed like MIM alternatives. It's the component that strikes the primer on every round you fire, so tighter tolerances and better materials matter more than most people realize. 

An upgraded firing pin reduces light strikes, improves consistency, and holds up longer under heavy use - pair it with one of our stripped Glock slides for a complete upper build. 

Sights, Barrels, Thread Protectors, and Other Accessories

Beyond internal components, we carry polymer fixed sights for the Glock 17, 19, and 26, plus Glock barrels including ported options for the Glock 17 Gen 3 that reduce muzzle rise. For threaded barrels, the Strike Industries thread protector keeps your crown safe between uses. Round everything out with Lucas Extreme Duty Gun Oil to keep your build running reliably for the long haul.
