L2d combat upper parts kit glock 9mm (for my glock 19) - chameleon - L2D Combat Upper Parts Kit, Glock 9mm

I've owned this L2D Combat Upper Parts Kit Glock 9mm in Chameleon since September 2019 and I am very pleased with the quality overall. Although there was a minor issue with the ISMI Striker Spring that came with the kit (caused light strikes), I called L2D and spoke with Greg and we concluded that it was a bad batch from ISMI, which is not L2D's fault at all. He sent me a Wolf Striker Spring right away for free as a replacement since they had to wait for a new batch of Striker Springs from ISMI. Eventually, they sent me a new ISMI Striker spring as well, which I have not tested because the Wolf spring has performed great with the rest of the kit. Other than that, the design, performance, and aesthetics are perfect. Also like my review on their Tyton Slide, I would like to mention the extremely great customer service that Greg and Jason from L2D have provided overall. Unbeatable customer service compared to many other companies out there!
