Rastus... the Venom is very small compared to what I perceive as holographic sights... I don't have an EOTech but have an older Bushnell I once used... the Venom is designed to fit on an auto loader pistol slide, and comes with a 1913 rail mounting plate as well as one for a factory prepped Glock... 1 3/4 long x 1 wide x 1 1/4 high.... I have mine mounted on a 1/2" riser... I have the 3 moa dot... the battery compartment is on top, and uses a 1632 coin battery
my USAF tech school was at Goodfellow AFB, San Angelo, Tx.... was treated very well by the locals back in 1970
