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.

Turkish Tactical

I’ve been looking at the new Tisas PX-9 Gen3 Tactical for a few months now and have found a lot to like about it. The third generation of the Tisas-made polymer-framed striker-fired pistol includes a 5.1-inch extended threaded barrel, accepts easy-to-find SIG P226 pattern double-stack mags, is offered in three finishes (black Tenifer, OD green, or FDE Cerakote), has a decent 4.5-pound flat-faced trigger, comes with steel suppressor-height Glock-pattern sights with a front fiber-optic, and has a factory micro red-dot slide cut in a Trijicon RMR/SRO pattern.

Proving reliable across the first 1,000 rounds of Barnaul import, CCI Blazer Brass, and Federal American Eagle 115-grain FMJ, I recently quieted down a bit and tested it with a suppressor.

A big one.

For reference, the overall length in this format was 16 inches and it balanced well between the full mag and the can. Keep in mind you could always shrink that down, for instance, the SilencerCo Omega 36M shown can be dropped to its short format, or you could use a lighter can such as an 8-ounce Osprey 9 2.0, but we are getting too much in the weeds here. You get the idea.

Tisas PX-9 Gen 3. Say what?

Posted on by Leave a comment

Tennessee-based SDS Imports is bringing in an affordable 9mm double stack with a ton of features, the Tisas PX-9 Gen 3.

SDS specializes in importing quality pistols, shotguns, and accessories. In the past few years, they have partnered with Tisas (pronounced “Tis-ash”) in Turkey to supply well-made M1911-style handguns to the U.S. market that have built a following through a combination of good reviews and affordable pricing. Newer and more modern is the PX-9 series of polymer-framed striker-fired pistols, with the third generation guns being the most feature-rich.

This brings me to the Tisas PX-9 Gen 3 Tactical I currently have under evaluation.

Gotta say, I don’t hate it as it has a lot of good things going for it including an RMR direct-mount optics cut, an extended threaded barrel, Glock pattern sights, P226 pattern magazines, a decent trigger, modular grip ergos, a ton of accessories, and the ability to use XD-M holsters– all for about $500.

It looks like a mix of every modern combat pistol– and for good reason
