Your Questions Answered
Is this legal to install on my pistol?
Installing this selector switch on a pistol creates a machine gun under the National Firearms Act (NFA). You must have a registered, transferable Glock auto-sear (drop-in auto sear) or a registered Glock frame/receiver to install this legally. We are an FFL and recommend consulting with your local dealer or a qualified NFA attorney to ensure full compliance before purchase.
How reliable is it out of the box?
Based on our staff’s hands-on experience, we recommend a break-in period. Run 50 rounds through the system in a controlled, legal environment to ensure all components are cycling smoothly before considering it for any serious use. This allows the detent and spring to seat properly.
Will this work with my aftermarket slide?
Compatibility is primarily with the frame and fire control group. It should function with most aftermarket slides, provided your slide and barrel combination can reliably cycle at a high rate of fire. Ensure your entire system is built to handle the increased stress of automatic fire.

Product quality is solid but the website could use some work. Hard to find what I was looking for at first. The Buy Selector Switch for Glocks – Purple itself? No complaints.

Did a lot of research before pulling the trigger on this purchase (pun intended). Read reviews on 3 different sites, watched YouTube videos, and ultimately went with polymer80warehouse.com because of the price and shipping speed. Not disappointed. Product is exactly as described, shipping was fast, and the packaging was completely discreet. Already eyeing a few more items in their Glock Switches section.

Product is fine but shipping took 6 days instead of the 3 they estimated. Not a huge deal but worth mentioning.
