First Impressions of Zaffiri Precision Glock 19 Gen 1-3 Upper Parts Kit

The Glock 19 is arguably the most popular pistol in the United States, praised for its reliability, size, and modularity. Building a custom Glock, or simply replacing worn parts, has become a cottage industry. The Zaffiri Precision Glock 19 Gen 1-3 Upper Parts Kit promises a high-quality, US-made solution for completing or upgrading a Gen 1-3 G19 slide. I was eager to evaluate if it lived up to the hype, given the competitive landscape of Glock aftermarket parts.

My interest in this particular kit stemmed from a recent project. I acquired a stripped aftermarket slide and needed to populate it with quality components without breaking the bank. Reliability and smooth operation were my primary concerns.

Upon unboxing, I was immediately impressed by the individual packaging of the components within the kit. Everything was neatly organized, and the parts appeared well-machined. The finish on each piece was consistent and free of blemishes.

I was considering parts kits from Glock themselves and Brownells. I ultimately chose the Zaffiri Precision kit because of its advertised tighter tolerances and the positive user feedback regarding smooth cycling. The price point also helped to seal the deal, sitting competitively within the market.

My initial impression was positive. The Zaffiri Precision Glock 19 Gen 1-3 Upper Parts Kit seemed like a well-made product that could potentially elevate my custom Glock build. I was excited to get it installed and see how it performed at the range.

Real-World Testing: Putting Zaffiri Precision Glock 19 Gen 1-3 Upper Parts Kit to the Test

First Use Experience

My first experience with the Zaffiri Precision Glock 19 Gen 1-3 Upper Parts Kit was at my local indoor shooting range. I had installed the kit in an aftermarket slide on my Gen 3 Glock 19 frame. I used a variety of ammunition, including 115 grain FMJ, 124 grain FMJ, and 147 grain HST.

The pistol cycled smoothly throughout the first 100 rounds. I experienced no failures to feed or extract, even with the different bullet weights. The slide felt more responsive than with a previous, less expensive parts kit I had tried.

The ease of use was noteworthy; the parts dropped in with minimal fitting required. I am a trained armorer but even a novice should be able to install the kit with some caution and the correct tools. I was pleasantly surprised by the overall fit and finish and smooth function of the kit.

Extended Use & Reliability

After several months of consistent use, the Zaffiri Precision Glock 19 Gen 1-3 Upper Parts Kit continues to perform reliably. I’ve put approximately 1,000 rounds through the pistol since installing the kit. I have experienced zero failures.

There are minimal signs of wear and tear. The finish on the parts is holding up well to repeated cycling and cleaning. Regular cleaning and lubrication are essential, but the kit itself requires no special maintenance.

Compared to other aftermarket parts kits I’ve used in the past, the Zaffiri Precision kit stands out for its consistent performance and durability. It has significantly improved the reliability and overall feel of my custom Glock build. I would choose it over the OEM and other kits in the future.

Breaking Down the Features of Zaffiri Precision Glock 19 Gen 1-3 Upper Parts Kit

Specifications

The Zaffiri Precision Glock 19 Gen 1-3 Upper Parts Kit is designed to complete the upper receiver of a Glock 19, Generations 1 through 3. It includes all the necessary internal components, with the exception of the barrel and guide rod assembly. These parts are sourced from US manufacturers and built to original Glock specifications.

• Extractor: Machined from heat-treated steel, ensures reliable case extraction. A quality extractor is essential for consistent ejection and preventing malfunctions.
• Extractor Depressor Plunger: Spring-loaded plunger applies pressure to the extractor. This pressure guarantees that the extractor maintains a firm grip on the cartridge rim.
• Extractor Depressor Plunger Spring: Provides the necessary tension for the plunger. This spring is critical for proper extractor function.
• Firing Pin Safety: Prevents accidental discharge by blocking the firing pin. This is a vital safety feature in modern firearms.
• Firing Pin Safety Spring: Ensures the firing pin safety is properly positioned. A functional spring guarantees the safety operates correctly.
• Slide Cover Plate: Secures the firing pin assembly within the slide. Made from durable polymer, it protects the internal components.
• Channel Liner: Ensures smooth travel of the firing pin through the slide.
• Recoil Spring Guide/Channel Liner Installation Tool: Necessary to install the channel liner without damage.

These specifications are important because they contribute to the overall reliability, safety, and performance of the Glock 19. High-quality materials and precise manufacturing tolerances ensure that the pistol functions consistently under various conditions. The kit provides a cost effective way to replace existing parts without searching out each part individually.
