Vortex has expanded the Defender family by adding a new standard-size red dot, called the Defender-ST.
This optic is slightly larger than the Defender-CCW, which debuted in March of 2023. Vortex sees this red dot filling the roll for larger pistols and shotguns as well.
In the electronics department, the Defender-ST utilizes a motion activation and a 10-minute auto-off to save battery life. In addition, it features a choice of either 3-MOA or 6-MOA dots and is listed as running 25,000 hours on a top-loaded CR2032 battery.

The optic utilizes a 7075 aluminum body with a polymer insert to make it durable. It also features a large windowed, hard-coated, aspherical lens, which provides a clear sight picture. This lens is further protected by texturing on the outside, which also aids shooters in racking the slide.

The optic comes with a rubber cover and Picatinny mount.
Additionally, it uses the DeltaPoint Pro footprint and also includes a comprehensive set of pre-packaged bolts for mounting the optic to a wide variety of firearms, removing a lot of guesswork.

The Defender-ST is available in stores now with an MSRP of $469 though retail prices are around $329.
