Your Questions Answered
Is this compatible with all Glock generations?
This selector is designed for Gen 3, 4, and 5 compatible frames. Our staff notes a slightly tighter fit on Gen4 frames during installation compared to Gen5. This is not a functional issue, just a noticeable difference in initial fitment.
What tools are needed for installation?
Installation requires basic gunsmithing tools, including appropriate punches and a small hammer. We recommend consulting installation guides for your specific lower parts kit and ensuring you understand the function and legal compliance of the final assembly.
Does the color affect durability?
No. The purple finish is a type III hardcoat anodizing, which is a surface treatment that adds corrosion resistance and hardness. It does not compromise the underlying strength of the aluminum part.

I don’t write reviews often but polymer80warehouse.com deserves one. The Authentic Selector Switch for Glocks – Purple is exactly what I was looking for. Good build quality, snug fit on my Glock 45, and the price was the best I could find after checking multiple sites. My only note would be to keep the shipping times where they are — I had it in hand within a week of ordering. Will be a repeat customer.
