Product Details
This is a factory Glock rear sight that fits your G20, G21, G29, G30, or G36 - it's the real deal from Glock, not an aftermarket knockoff. The white dot is easy to pick up in most lighting, and being fixed means there's nothing to adjust or break off. Steel construction means it'll hold up to regular use without fussing. Just make sure you've got one of those models before ordering - it won't work on the G42 or G43.
