Yes, the Sightron SRS-2 6MOA Red Dot Sight can be mounted to a Springfield 9mm handgun using the correct adapter plate. The specific adapter plate needed depends on the specific model of Springfield 9mm handgun you are asking about. The Sightron SRS-2 6MOA Red Dot Sight uses the Docter/ Vortex Viper and Venom footprint so one of the plates listed below should work for most Springfield Handguns.

The Sightron SRS-2 sight at the link below uses the CMORE mounting footprint so you would need to use the compatible MOS mounting plate to mount it to a Glock 19 MOS.

In order to mount the Sightron SRS-2 6MOA Red Dot Sight to a Ruger Max 9 you would need to use an adapter plate that gives your Ruger a Vortex Venom footprint. Unfortunately we do not carry the correct adapter plate for the Ruger Max 9. However, Evolution Gun Works makes a ""VORTEX VIPER / VENOM RED DOT SIGHT MOUNT FOR RUGER MAX-9"" adapter plate that will work. Once you get the adapter plate, you can mount this optic as well as any optic that shares the Vortex Viper footprint.
