If you are working on a Polymer80 build or even wanting to overhaul your existing Glock, there are a ton of parts on eBay. You can find some good deals but I would recommend you stick with reputable brands and sellers. For the sellers, I would look for lots of sales – at least over 30 and ideally hundreds – and very good scores. There are cheap imports/knock-offs showing up so beware no-name stuff.
The following are all real-time listing on eBay so you can go there and find parts.
