Vortex Defender-ST 3 MOA Red Dot Sight, Black, 1.8in, 1.48oz, DFST-MRD3
Compatibility Tags
Overview
The Vortex Defender-ST is the middle of the Defender pistol optic line, larger than the CCW but easier to holster than the XL. It uses the DeltaPoint Pro footprint, ships with a Glock MOS plate, and fits Gen6 Glock ORS/DPP plate setups through the same footprint family.
For Glock 47 and Glock 49 buyers, the ST is the practical Vortex pick: enough window for fast dot recovery on a duty-size slide, but not so large that every holster choice collapses. The top-loading CR2032 battery avoids removing the optic for battery swaps, and Vortex includes common screw sets plus a Picatinny mount in the box.
