New DHS Sidearm SIG SAUER’s P320C Currently In FAT

Thursday, October 12th, 2017

Although the Department of Homeland Security selected the compact variant of the SIG P320 early this year, it was kept quiet.

Initially, there was the matter of a Government Accounting Office protest to wait on. That cleared up fairly quickly, but still the Department has kept mum on the subject despite an announcement via InSight, their internal news system. This screenshot originated on


Currently, the P320C is in First Article Testing, a process which ensures production models will meet the same government requirements as the prototypes did during the solicitation.

This is the pistol they selected, as seen at AUSA.


Of the commercial P320 line, the DHS pistol is closest to the closest to the X Carry. Additionally, each fielded firearm comes with eight magazines, a cleaning kit, parts to support use out to 10K rounds, HD sights, training, manuals and cable lock, as per the contract.

SIG SAUER Introduces 6.5 Creedmoor Match Grade Ammunition

Tuesday, September 12th, 2017

Newington, NH (September 11, 2017) – SIG SAUER, Inc. extends its Match Grade Elite Performance Ammunition line for rifles with the addition of a 6.5 Creedmoor Open Tip Match (OTM) round. Featuring a 140gr Sierra MatchKing® bullet, this new 6.5 Creedmoor load has a muzzle velocity of 2,625 fps with muzzle energy of 2,142 ft-lbs.


Designed for superior accuracy, the SIG 6.5 Creedmoor Match Grade load performs exceptionally well in wind, thanks to its high ballistic coefficient, delivering a flat trajectory with minimal recoil.

“The 6.5 Creedmoor is one of today’s most popular cartridges with competition shooters and hunters alike,” said Dan Powers, President of the SIG SAUER Ammunition Division. “It is an impressive, flat-shooting round that delivers precision in challenging, windy conditions.”

Engineered to excel in today’s precision rifles, SIG SAUER Match Grade Elite Performance Ammunition uses a temperature-stable propellant that delivers consistent muzzle velocity in all weather conditions. Premium-quality primers ensure minimum velocity variations, and the shell case metallurgy is optimized in the SIG Match Grade OTM cartridge to yield consistent bullet retention round to round. All SIG SAUER rifle ammunition is precision loaded on state-of-the-art equipment that is 100% electromechanically monitored to ensure geometric conformity and charge weight consistency.

Fire Control Unit – X01 for the SIG P320

Monday, September 4th, 2017

The EXO ONE (X01) is pretty slick. It takes advantage of the SIG P320 Fire Control Unit (FCU) as a plug-and-play component. This multi-caliber exoskeleton accepts the FCU, barrel, slide assembly, and magazine release and can be configured in 9x19mm Parabellum, .357 SIG, and .40 S&W by transplanting the corresponding P320 components (.45 ACP is in development, as the changes in magazine well dimensions require a specialized lower receiver).


It features a non-reciprocating charging handle locks the action open (the slide to the rear) with an upward motion when fully retracted. The action can then be released with a downward motion (akin to HK-style weapon systems). In addition, if the charging handle is in the forward position, the slide can be released via the FCU slide release during reload procedures. The X01 features three M-Lok slots near the muzzle for accessory and grip attachments. The upper receiver features a 19-slot milspec M1913 picatinny rail.


Like the SIG MCX and MPX, the rear of the lower receiver features a vertical M1913 Picatinny rail to accept SIG MPX/MCX buttstocks and arm braces.

SIG SAUER Launches MCX Rattler

Tuesday, August 22nd, 2017

I knew SIG had been working in a new, compact version of MCX. They’d been refining this design for awhile, having heard rumor of it overseas as far back as two years ago during DSEI. Later, after asking about it, I was shown developmental models. Today, it all becomes clear. SIG SAUER is launching the Rattler, the latest addition to the MCX family. I got a chance to speak briefly about the gun with Patrick Hanley, Rifle Product Manager at SIG.

The first question I asked him was about the name. I’d been hearing it float around for quite awhile and wondered where it came from. Apparently, after firing it on full-auto the first time, the designer said, “It really rattles your teeth when you fire it.” Considering the nickname of MCX, Rattler stuck.

Next, I asked him why they built it. Hanley answered, “Everything was designed to be as discrete and small as possible with this gun.” Quite simply, customers came to them and asked for a Subgun size weapon in 5.56mm or .300 BLK. This is the result of that work.

Initially, they leveraged the MCX short stroke piston design, but quickly found that the upper would have been longer than the 5.5″ barrel. Instead, they developed two separate gas systems, one for the .300 and a second for the 5.56.

The .300 gas system has two positions and can be used suppressed. The 5.56 is a plugged gas system to prevent valve corrosion. Unfortunately, it cannot be used with a suppressor; not at that length. However, swapping between calibers, is as simple as swapping barrels.

The stock was designed so that all controls can be manipulated with it closed and the weapon itself can be fired with the stock closed, making it a very compact package. Additionally, the Rattler’s upper receiver has no forward assist and their slick side deflector for spent cases.

SIG may have succeeded in creating the smallest production AR-style weapon in the world. It’s 16″ while folded and 23.5″ with the stock extended.

Based on these differences, the Rattler comes as a complete pistol (with SPB) or SBR. The barrels are not compatible with any other MCX upper, so SIG is offering dedicated Rattler Upper Receiver Kits which come with the AR lower adapter knuckle. The Rattler upper kit can be used with an MCX lower or AR lower, when used with the adapter knuckle.  For owners of Rattlers, barrel kits to swap calibers will be available so they don’t have to purchase complete URGs. 

The MCX Rattler launches today.

UPDATE: .300 Rattlers will ship next week and 5.56 in November.>

SIG SAUER Issues Voluntary Upgrade of P320 Pistol

Wednesday, August 9th, 2017

P320 pistol meets requirements for industry and government safety standards; performance enhancements optimize function, safety, and reliability.

Newington, NH (August 8, 2017) – The P320 meets U.S. standards for safety, including the American National Standards Institute (ANSI) / Sporting Arms Ammunition Manufacturers’ Institute, Inc. (SAAMI®), National Institute of Justice (NIJ), as well as rigorous testing protocols for global military and law enforcement agencies.

The design of the SIG SAUER P320 overcomes the most significant safety concern in striker- fired pistols today: the practice of pressing the trigger for disassembly. This can be performed with a round in the chamber which has resulted in numerous incidents of property damage, physical injury, and death. The disassembly process of the P320, however, uses a take-down lever rather than pressing the trigger, eliminating the possibility of discharge during the disassembly process.

Recent events indicate that dropping the P320 beyond U.S. standards for safety may cause an unintentional discharge.

As a result of input from law enforcement, government and military customers, SIG has developed a number of enhancements in function, reliability, and overall safety including drop performance. SIG SAUER is offering these enhancements to its customers. Details of this program will be available at on Monday, August 14, 2017.

The M17 variant of the P320, selected by the U.S. Government as the U.S. Army’s Modular Handgun System (MHS), is not affected by the Voluntary Upgrade.

“SIG SAUER is committed to our approach on innovation, optimization, and performance, ensuring we produce the finest possible products,” said Ron Cohen, President and CEO of SIG SAUER. “Durability, reliability and safety, as well as end-user confidence in the SIG SAUER brand are the priorities for our team.”

SIG SAUER Acknowledges P320 Trigger Issues With -30deg Drop, M17 MHS Unaffected, Announces Voluntary P320 Upgrade

Tuesday, August 8th, 2017

In response to recent internet reporting on the safety of the SIG SAUER P320, the company invited us, and other members of the gun media, to their facility in New Hampshire to address the issues. Because the US Army’s new M17/18 Modular Handgun System is based on the commercial SIG P320, I wanted to find out if the M17 is safe for use by service members.

Bottom Line Up Front – SIG acknowledges that the commercial P320, used by armed citizens and members of Law Enforcement, may unintentionally discharge if dropped at a -30deg angle. Consequently, they will be offering a voluntary upgrade. SIG is hiring additional customer service reps to work on this. As I will discuss below, this issue does NOT affect the M17/18 Modular Handgun System.

Initially, the group met with CEO, Ron Cohen. He was very direct and got right at the heart of the matter. Cohen began by stating, “SIG spends a lot of money on developing and producing products.” He went on, “We spend more on product development and testing than anyone else in industry. Most companies spend between 1.1-1.3%, but we spend 4% of our budget on product development.”

“Our customers make us who we are. They constantly drive us to make ourselves better.”

Ron Cohen

“The conversation of safety is complex,” said Cohen, “It has many layers.” For years, Ron Cohen didn’t want to develop a striker fired pistol. He worried about safety in disassembly as well as accidental discharges and didn’t want to disassemble the handgun by pulling the trigger. Consequently, it took 10 years to design and build a striker fired pistol. Instead, they relied on their tried and true SA/DA architecture.

“Drop safe,” Cohen explained, “Those two words don’t exist together. No gun is drop safe. It’s a function of angle, height and surface. If you build it completely drop safe, you legitimize mishandling. Inherently guns are not meant to be dropped, and are unsafe when dropped.”

All SIG pistols, including the P320 are tested to the following industry and government standards: ANSI/SAAMI, NIJ, FBI/DOJ, TOP, Massachusetts, and California DOJ as well as various others. They are very specific tests, most of which are conducted by outside labs. The P320 has passed all of those tests. Unfortunately, they don’t test the pistol’s performance when dropped at a -30deg unto concrete. They could drop test a pistol in every conceivable combination of angles on three axes, but that’s 46,000,000 different ways. Consequently, manufacturers build to a standard.


When asked if the existing testing protocols were good enough, Tom Taylor, Executive Vice President of Commercial Sales replied, “not for us.”


To that end, SIG engineers spent the weekend conducting 2,200 drops using 11 pistols across three different test protocols. They included dropping the pistol at a -30deg angle.  Interestingly, they learned that a beavertail doesn’t completely mitigate the danger of an unintentional discharge but it does help by absorbing some of the impact. 


We were able to examine the test apparatus and demonstrated three drops each with three compact P320s equipped with the Enhanced Trigger.  There were zero unintentional discharges.  


While the MHS passed DoD’s TOP 3-2-045 test with the trigger currently in the commercial P320, SIG proposed an enhanced trigger via Engineering Change Request E0005. As it didn’t result in additional cost to the government and only improved the firearm’s performance, M17s currently being delivered to the US Army have this trigger. Additionally, this trigger also eliminates the “double click” felt during P320 trigger pull.


Although SIG was already working toward introducing the MHS-inspired Enhanced Trigger to the P320, this -30deg drop issue has hastened their effort. They have lightened the Trigger, Striker and Sear by about 30% overall and added a Disconnect (commercial only, not MHS). The trigger pull weight is unaffected, but rather the trigger part actually weighs less. The reason they lightened those parts is to mitigate the momentum gained by the heavier parts during a drop.

Taylor laid it out, “There is a vulnerability with the P320 at the -30deg drop.” They plan to incorporate the trigger enhancements for the M17 into the P320. They’d been working on them, but implementation wasn’t imminent. Based on what they’ve found, that has been accelerated. Details on their voluntary upgrade program will follow soon.

I want to put this perspective. Since it’s introduction in 2014, they’ve sold around 500,000 P320s. There are three recorded cases of unintended discharges in LE channels . There is one additional commercial incident which I am familiar with but was not formally reported to SIG. That’s four known incidents from 500,000 weapons, many of which are used on a daily basis. Additionally, those incidents have all been within the last year.


Tom Taylor finished up with this statement, “We believe it’s the safest striker fired pistol on the market. We built it to address the most dangerous scenario.”

My take is that despite building their pistols to industry standards, SIG has acknowledged the issue and is taking steps to fix it. They didn’t waste any time. They’ve stopped commercial production of the P320 and are concentrating on the upgrade. It’s going to be more than just swapping parts. The slide and frame will need some work as well so the pistol will need to go back to SIG. Details will soon follow on how to participate in the voluntary upgrade program.

SIG SAUER Reaffirms Safety of P320 Pistol

Striker-fired pistol exceeds safety standards of ANSI/SAAMI® and U.S. military testing

Newington, NH (August 4, 2017) – In response to social media rumors questioning the safety of the P320 pistol, a variant of which was selected by the U.S. government as the U.S. Army’s Modular Handgun System (MHS), SIG SAUER, Inc. has full confidence in the reliability, durability and safety of its striker-fired handgun platform. There have been zero (0) reported drop-related P320 incidents in the U.S. commercial market, with hundreds of thousands of guns delivered to date.

The P320 meets and exceeds all U.S. standards for safety, including the American National Standards Institute (ANSI) and Sporting Arms and Ammunition Manufacturers’ Institute, Inc. (SAAMI), as well as rigorous testing protocols for global military and law enforcement agencies.

All SIG SAUER pistols incorporate effective mechanical safeties to ensure they only fire when the trigger is pressed. However, like any mechanical device, exposure to acute conditions (e.g. shock, vibration, heavy or repeated drops) may have a negative effect on these safety mechanisms and cause them to not work as designed. This language is common to owner’s manuals of major handgun manufacturers.

As a result, individual attempts to perform drop tests outside of professionally controlled environments should not be attempted.

“SIG SAUER is committed to producing only the finest products,” said Ron Cohen, President and CEO of SIG SAUER. “Safety and reliability have been and always will be paramount to the SIG SAUER brand.”
