The ADE Advanced Optics RD3-006x includes a Glock dovetail adapter, allowing for installation on Glock pistols that are not optic ready (MOS) from the factory. If you have an MOS model 43X, you cannot install this optic. 43X MOS pistols accept optics with the RMSc footprint, direct fit options include the Sig Romeo Zero, Shield RMSc, Vortex Defender CCW and more.
