Why a flexure arm matters in a pistol red dot…

Posted on by Leave a comment

SIG debuted the closed emitter Romeo M17 – which, as its name would imply, is built from the ground up as a near “bomb-proof” red dot for the military’s M17 and M18 Modular Handgun System pistols – earlier this year. Constructed of forged 7075 aluminum with a beryllium copper flexure arm (more on that in a minute) the Romeo M17 has an extremely low deck height so that armorers can reuse standard iron sights, has 15 illumination settings (including three for use with Gen 3+ night vision), beats drop and submersion tests, and, importantly, has an integral loaded chamber gas deflector shield that keeps the MHS from gassing up the lens after 10-15 rounds.

The sight has been spotted in military use, it has been submitted to the Army’s Soldier Enhancement Program, it has an NSN number, and SIG tells us a large public safety contract announcement is soon to break on the optic as well.

The Romeo M17 is a hoss. This installed example I saw dropped from 10 feet onto concrete at SIG’s plant in Oregon earlier this year with nothing but cosmetic damage to the housing. SIG explained to Guns.com that the Romeo M17 has surpassed 100,000 rounds in testing without loss of zero or parts breakage. (All photos except noted: Chris Eger)

Part of what makes the Romeo M17 so tough is an innovative beryllium copper flexure arm that replaces springs with a much more robust part – which adds to durability – and helps drop the deck to allow a better co-witness with standard iron sights.

That magical Romeo M17 flexure arm.

Installed near the base of the Romeo M17, the arm provides a backbone – so to speak – for the sight, cutting down on the number of parts that can fail.

The problem is, the Romeo M17 uses a unique mounting footprint, one that has six leverage points and uses 40 pounds of torque with a single optics plate mounting screw. In short, unless you have an M17 or M18 military or commemorative handgun, you can’t mount it.

That’s where the Romeo X comes in.

What’s the Difference between the SIG Romeo Zero, 1, & 2 Pistol Optics?

While Glock, S&W, and others sell pistols and have optics cuts on a lot of their newer models, SIG is kind of unique in the respect that they make both handguns and compatible red dots as well.

Over the past few months, I have been doing my own research when it comes to the company’s Romeo series (Zero, One, Two, Three Max, etc) of pistol-mounted red dots and have put together a guide to the above in my column at Guns.com.

Not gonna lie, tho, I like the Romeo 2 myself, it has proved bombproof in a T&E 10mm P320 XTen over the summer.

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)
