Warfighting, like any line of work, gets much easier when you have the right tools for the job. A long barrel and high powered optics may make you a lethal opponent in the long-range shootouts of Afghanistan, but that same loadout could quickly become a liability in the close-quarters battles of Baghdad. Of course, some circumstances may call for both accuracy at a distance and the rapid target acquisition of an in-your-face fight, and in those situations, you’ve got to make do with what you’ve got.
That’s where platforms like FLUX Defense’s MP17 for the new Army standard issue M17 pistol could come in. Instead of replacing the Army’s existing sidearm, FLUX Defense went to work on finding ways to make Sig Sauer’s M17 more lethal and efficient in situations where one might not normally reach for a sidearm. In order to do that, they found what the M17 really needed was a third point of contact on the user’s body.

Most special operators rely on a pistol as a secondary firearm, using their primary weapon (commonly an assault rifle or submachine gun) whenever possible thanks to its greater degree of control, accuracy, range, and often, ammunition on hand. A sidearm like the Army’s M17 pistol is often seen as a weapon of last resort, or at the very least, a weapon with advantages under only specific circumstances.
The FLUX Defense MP17, however, adds a retractable stock (though, it’s important to note, it’s not legally considered a stock) and accessories to the standard Sig Sauer M17. The retractable stock and custom holster means the pistol still rides on a soldier’s hip like the M17 normally would, but instead of drawing the weapon and firing it like a traditional pistol, the user can deploy the stock and shoulder the weapon like a rifle — adding a great deal of stability, accuracy, and recoil control that wouldn’t otherwise be possible.
While current M17s come standard with either a 17-round or extended 21-round magazine, the MP17 increases that capacity to 43 rounds, thanks to a second magazine holder that doubles as a forward grip. It also offers a rail for mounting lights or lasers and optics mounts on the back. Importantly, beneath that optic mount is a gap that allows users to continue to use the pistol’s iron sights even while it’s housed in the FLUX brace.
According to the manufacturer, you can convert your standard-issue M17 into the MP17 in as little as 60 seconds, and it weighs in at just 2.8 pounds with the firearm (and no ammunition) installed.
FLUX advertises that the platform “shoots like a primary, holsters like a pistol,” and for many special operators or even those with concerns about home defense, that’s an offer that’s too good to ignore. This system could also serve as a significant benefit for personal security details and pilots — both of whom are constantly balancing security and preparation against a lack of usable space.
Last year, fighter pilots began carrying a new M4 variant dubbed the GAU-5/A Aircrew Self Defense Weapon, which breaks apart to be easily stowed in the cockpit. A platform like the FLUX MP17, however, could be used to those same ends without requiring assembly after a crash.
The holster allows for suppressors, flashlights, lasers, or whatever else you crazy kids are using these days.
Civilian customers can purchase the brace system without its custom holster for around 0, or with the holster for 0. As FLUX will point out, there aren’t currently any other holster options available on the market for the platform, however, so you’ll probably want to spring for the full package. That duty holster is open near the muzzle, allowing for a wide variety of flashlights, suppressors, or other tacticool (or legitimately tactical) add-ons. They also sell variants for use with Glock pistols.
Of course, despite being classified as a pistol brace rather than a stock, there could potentially still be legal issues with picking up your own MP17. While FLUX doesn’t sell their brace kit as a Short Barrel Rifle kit (SBR) and they say it doesn’t fall under the ATF’s AOW (All Other Weapons) category to require a special stamp, the ATF is sometimes slow to make rulings about new products. It’s also a good idea to familiarize yourself with any state or local laws pertaining to the use of SBRs before you make a purchase.
Provided you can get your hands on the FLUX Defense MP17 legally, it may be just what you need to turn your standard sidearm into the right tool for the job, even if the job at hand is something pistols have no right to be doing.
