This sight uses a CR2032 battery. It installs from the bottom so you have to remove the sight from the base to replace it. The battery doesn’t securely snap into place and pops out when trying to reinstall the base, which is rather annoying.
It fits my weaver rail so it should fit a picatinny
The SOUSA OPTICS Raid Pistol Dot Sight RPD utilizes the Trijicon RMR mounting footprint. So if you have an MOS (optics ready) model Glock 19, you would use the included plate #2 to fit this optic. If you do not have an MOS model Glock 19, you can use an adapter that requires you to remove your rear sight, and replace it with a plate that uses the Trijicon RMR footprint. You can find the correct adapter plate in the link below:
