XTS Large Windows Glock 19 RMR Cut Slide Review

Let’s Dive into XTS Large Windows Glock 19 RMR Cut Slide

The XTS Large Windows Glock 19 RMR Cut Slide is an aftermarket slide designed to upgrade your Glock 19, offering enhanced aesthetics, improved performance potential, and the ability to easily mount a red dot optic. Manufactured by XTS, this slide aims to provide a reliable and visually appealing alternative to the factory Glock slide. The large windows are a standout feature, reducing weight and potentially aiding in heat dissipation, while the RMR cut allows for seamless installation of popular red dot sights.

I was looking for a way to improve the accuracy and overall look of my Glock 19, and the ability to mount an RMR without needing a separate adapter plate was a huge draw. I had been experiencing some issues with the stock slide cycling consistently with lighter loads. An aftermarket slide that potentially offered improved tolerances and lighter weight seemed like the perfect solution.

Upon unboxing the XTS Large Windows Glock 19 RMR Cut Slide, I was immediately impressed with the fit and finish. The Cerakote coating felt smooth and durable, and the machining was clean and precise. The slide felt noticeably lighter than the factory slide, which I anticipated would reduce felt recoil.

I considered a Zev Technologies slide and a Brownells RMR cut slide. I chose the XTS Large Windows Glock 19 RMR Cut Slide because it offered a similar feature set at a more affordable price point, and the large windows provided a unique aesthetic that I found appealing. It also came with an RMR cover plate, which was a nice bonus.

My first impression was excitement mixed with a little apprehension. I was eager to see how it would perform at the range, but also concerned about potential reliability issues that can sometimes arise with aftermarket parts.

Real-World Testing: Putting XTS Large Windows Glock 19 RMR Cut Slide to the Test

First Use Experience

I tested the XTS Large Windows Glock 19 RMR Cut Slide at my local outdoor shooting range. I wanted to assess its reliability and accuracy with various types of ammunition. I shot approximately 300 rounds of 115gr FMJ, 124gr FMJ, and 147gr JHP ammunition through it.

The weather conditions were typical for a summer day – hot and humid. I experienced no malfunctions during the initial testing session, and the slide cycled smoothly with all ammunition types. The lighter slide seemed to reduce muzzle flip slightly, making it easier to stay on target for follow-up shots.

The slide was easy to install and required no gunsmithing. The RMR cut was precisely machined, and my Holosun 507C X2 mounted securely with no issues. Initially, the slide felt a little tighter on the frame than the factory slide, but after a few magazines, it smoothed out considerably.

After the first range session, I noticed a small amount of finish wear around the ejection port. This was likely due to the increased velocity of the ejected casings, but it was purely cosmetic.

Extended Use & Reliability

After several months of use and approximately 1500 rounds fired, the XTS Large Windows Glock 19 RMR Cut Slide has held up remarkably well. It continues to function reliably, and I have experienced no malfunctions related to the slide itself. The Cerakote finish has proven to be quite durable, with only minor wear marks in high-friction areas.

I regularly clean and lubricate the slide after each range session. It disassembles easily, and the internal components are accessible for thorough cleaning. The XTS Large Windows Glock 19 RMR Cut Slide has proven to be easy to maintain.

The XTS Large Windows Glock 19 RMR Cut Slide has exceeded my expectations. It offers a noticeable improvement in performance and aesthetics compared to the factory slide. It has become a trusted and reliable component of my Glock 19 setup.

Breaking Down the Features of XTS Large Windows Glock 19 RMR Cut Slide

Specifications

• Manufacturer: XTS.
• Gun Make: Glock.
• Gun Model: Glock 19 Gen 1, Glock 19 Gen 2, Glock 19 Gen 3. It’s important to note the compatibility limitations with only Gen 1-3 Glocks.
• Finish: Cerakote. Cerakote provides excellent corrosion resistance and comes in various colors.
• Fabric/Material: 17-4 Stainless Steel. 17-4 stainless steel is known for its high strength and durability, making it ideal for slide construction.
• RMR Cut: Accepts Trijicon RMR and Holosun 507C X2 (Tapped 6-32). This allows for direct mounting of popular red dot sights without adapter plates.
• Lowered Ejection Port: Enhances ejection reliability. A lowered ejection port helps prevent stovepipes and ensures consistent ejection of spent casings.
• Forward Exposed Barrel Cut: Aesthetically pleasing and potentially aids in heat dissipation.
• Large Windows: Reduces slide mass. The reduced mass aids in faster cycling and potentially less felt recoil.
• CNC Aluminum RMR Cover Installed: Protects the RMR cut when an optic is not mounted.

These specifications are crucial because they directly impact the slide’s performance, durability, and compatibility. The 17-4 stainless steel ensures long-lasting reliability, while the Cerakote finish provides excellent corrosion resistance. The RMR cut enables easy optic mounting, significantly improving target acquisition and accuracy.
