Sig Goes Modular in Pistol Red Dots
New Hampshire-based Sig Sauer this week announced that the new Romeo 2 red dot is now shipping, in a choice of four different reticles
Billed by Sig as designed and built “for the most rugged and adverse conditions” the Romeo 2 uses a 7075 aluminum housing that features a modular shroud system including two steel shrouds to provide multiple layers of protection and allow the user to configure their optic in three different profiles.

Two steel shrouds and a polycarbonate rear window allow the Romeo 2 to be used in three different configurations from open to fully enclosed. The optic is rated IPX7 when it comes to waterproofing. (Photo: Sig)

It also is night-vision friendly for goon work, with Sig’s Dark Adaptive Reticles & Coating system and three of the 15 brightness settings are specifically for use with PNVs. A MAGNETAC system automatically turns off the optic when holstered with a compatible holster and turns in on when drawn. (Photo: Sig)

You’ve got me seriously considering diving into the modular world of Sig Sauer optics! The Romeo 2’s adaptability with those steel shrouds and multiple configurations sounds fantastic. How easy is it to actually switch between setups? And have you noticed any impact on accuracy or sight picture depending on the chosen configuration?”
I’ve been running it in the fully enclosed flavor on a 10mm (SIG P320 XTen) for several months. Have about 500 rounds through it thus far with no issues. Still on the original battery.
