Any sights specifically designed for GLOCK® 9mm pistols (models 43/43X/48 excluded), are appropriate for use on RIVAL ARMS™ slides.
NOTE: certain styles of sights may extend over the optics cover plate. This style of sights may still be installed and used, however this style of sight will preclude the use of a red-dot optic. Be sure to know if you intend to use an optical sight, you will need to install MOS sights that do not extend over your optics plate.
