SIG Sauer Electro Optics is releasing a new branch of the Romeo family of slide mounted electronic red dot sights for handguns: the SIG Romeo X Series. The new SIG Romeo X Series are inspired by SIG Sauer’s military grade M17 Romeo optics but optimized for civilian EDC (every day carry) needs and purposes. Currently there are two different red dot sights in SIG’s X Series lineup: a standard-size unit compatible with duty sized guns such as the Sig P320 and a slimline variant meant for guns like the SIG P365 series.

SIG Sauer Romeo X Series sights are designed with a “low deck” height which allows the sight to co-witness more easily with the pistol’s iron sights. Traditionally, when it comes to slide mounted red dot sights, users who wished to keep their irons sights would need to install suppressor height front and rear sights in order to clear the base of most slide mounted optics. Today, though, the trend is towards optics with lower bases that do not need taller than normal sights, as is the case with the new Sig Romeo X Series.

“The Romeo-X family of red dot sights is completely optimized for everyday carry and built using the same technology and testing standards of our mil-spec optics that are designed to withstand the rigors of the battlefield,” said Andy York, President, SIG Sauer Electro-Optics. "The Romeo-X Series is designed for ease of use beginning with the side battery placement leading to an overall low deck height of the sight. This profile gives the optic an extremely low position when mounted to the slide for a full sight picture and co-witness with the existing standard-height iron sights. The Romeo-X Compact and ROMEO-X Pro are engineered, tested, and built-in Oregon to be the ultimate aiming solution for EDC.”
