At the Vector Optics booth at SHOT show, I got hands-on with an Owlset HEIM ES X-NANO mini thermal pistol sight. This claims to be the world’s smallest pistol-mountable thermal optic. Holosun has a similarly sized optic display but that actually comes in two parts, with a camera section mounted like a pistol light. This Owlset is a self-contained unit, with the lens in its front. It utilizes Vector Optics VOD footprint, which is a variant of the AimPoint ACRO. Vector Optics offers MOS, RMR, and Picatinny adapter plates.
The MSRP was tentatively targeted to be under $600, but with US tarrifs, that’s anybody’s guess at this point? But it’s already available in Asia and set to be released in Q1 here in the US.
