Sig Sauer MPX 9mm sub-machine gun review

While 9mm SMGs aren’t as tactically relevant as they used to be, there is still a market and a place for them. I’m a huge fan of the Sig MPX, and now that they’re offering it in a carbine version makes me genuinely happy. 9mm rifles/subguns are awesome fun, and while they may not be as practical as a rifle, you can do a lot worse for a defensive firearm.

SIG SAUER® Introduces .38 Super +P Elite Performance Ammunition

Newington, NH (October 7, 2015) – SIG SAUER, Inc., designer and manufacturer of the world’s most reliable firearms, silencers, optics, ammunition, airguns, and accessories is pleased to introduce 125gr .38 Super +P Elite Performance Ammunition in V-Crown™ jacketed hollow point (JHP) and SIG FMJ full metal jacket loads.

With a muzzle velocity of 1230 feet per second, the 125gr .38 Super +P ammunition delivers exceptional accuracy and reliability. The SIG V-Crown load features a proprietary stacked hollow point bullet for reliable, uniform expansion and optimal terminal performance. DUCTA–BRIGHT 7A™ coated brass cases also provide enhanced lubricity, offering superior corrosion resistance, and more reliable feeding and extraction in semi-automatic pistols.

The SIG FMJ premium target loads feature solid brass cases and durable, copper-jacketed bullets that remain intact on impact. The precise, uniform profile of the SIG FMJ bullets results in maximum accuracy and consistency. Dependable primers and clean-burning powders are used for reduced barrel fouling with more reliable functioning.

“With the introduction of the .38 Super +P ammunition, we now offer Elite Performance Ammunition for all SIG SAUER pistols,” said Dan Powers, president of the SIG SAUER Ammunition Division. “SIG FMJ ammunition is the perfect combination of affordability and performance in a premium target round. It is designed to approximate the performance of the corresponding SIG V-Crown jacketed hollow point rounds, giving our customers the advantage of a seamless transition from target ammo to carry ammo.”

All Elite Performance Ammunition is manufactured in the United States by SIG SAUER to the same exacting standards as the company’s premium pistols and rifles. For more information, visit

SIG Sauer P239: The gun I’ve always wanted (and have never bought)

P239_SAS_Nitron_L_sm-FWhat does it say that I’ve always wanted a P239, but I’ve never bought one? I didn’t want one that bad? There was no story to go with it? I don’t know. It’s always in the back of my mind though. An all-metal single stack 9mm with a DA/SA trigger is a bit of a departure from my regularly preferred plastic fantastics, but I’ve always had a soft spot for this.

Do you have a gun you want but have never gone out of your way to add to the collection?

From NRA Annual Meetings: The Sig P239 Tactical


While cruising the floor of NRA Annual Meetings, I made my ritual stop at the Sig Sauer booth, to handle guns I can’t afford. Usually I don’t make it past their competition section, full of X5s and SAO P-series guns, but that day I wandered just a bit.

SIG Sauer suing ATF

At SHOT Show 2013, Sig Sauer announced a version of the MPX Carbine that would have a 6.5 inch barrel and come standard with a permanently welded 9.5 inch long muzzle brake. The get up looked like this:


The ATF took one look at the gun and said “that’s not a muzzle brake because those are clearly the baffles from a suppressor, and we’re saying that device is officially a suppressor.” Usually when that happens, companies will return to their offices, tails tucked between their legs, duly chastised. But not this time. Not Sig. In fact, Sig has gone the opposite route, deciding instead to spit in the tyrant’s eye sue the ATF.

[Sig Sauer’s] suit, filed in the U. S. District Court of New Hampshire, states that it submitted a rifle, with its muzzle brake, to the ATF on April 4, 2013 for evaluation. The device is described as 9.5 inches long and permanently attached with a weld to a 6.5 inch barrel, making the overall barrel length 16 inches.

The ATF responded, by letter dated Aug. 26, 2013, that the device is constructed as a silencer component commonly referred to as a “monolithic baffle stack,” the suit states.
“Welding it to a barrel does not change its design characteristics or function,” Sig says it was informed by the ATF.

The news of this lawsuit from Sig comes on the heels of the ATF’s recently letter declaring that the Sig Pistol Brace is not a stock, regardless of how it’s used by the end user. It seems to be part of a trend from Sig on pushing the limits, and honestly, it’s one that we here at Gun Nuts support wholeheartedly. In a perfect world, there would be no NFA list; in a nearly perfect world the only things on the NFA list would be actual machine guns and destructive devices. I’d love to see the NFA deregulated and suppressors and SBRs moved off; and maybe that will happen some day.

In the meantime, we wish the best of luck to Sig with this lawsuit. The analysis of the merits of the suit are interesting, because if the muzzle device does not suppress sound in any way, can it really be classified as a suppressor? If the case is interpreted purely on the performance of the muzzle device as it is attached to the barrel, then it’s clearly not a suppressor. However, the ATF seems to think that because it could be readily made into a suppressor, that it should be classified as one from the get-go.

Using Sig’s Arm Brace to Poke the ATF

20140409-104258.jpgWhile working on my interior design degree I saw a lot of unrealistic projects. Often, students who attempted to create something utterly original, forgot about things like gravity and good taste. My perusuit of an education in an applied design (instead of a major like painting or sculpture), was specifically chosen to avoid such work. Continue reading “Using Sig’s Arm Brace to Poke the ATF”

Gun News: Sig Sauer discontinues all models but P-series classics and MPX

In news that will shock many, today Sig Sauer discontinued a massive number of guns in their product line. All handguns other than the classic P-series guns such as the P226 and P229 have been dropped from the lineup, effective immediately according to a source inside Sig. On the rifle side, all long guns other than the new MPX submachine gun have been dropped as well. A Sig Sauer insider was quoted saying “Look, we all know what you want is more P226s and P229s, but for years we kept making diamond plate rainbow compact 1911s. We’re really sorry about all of that, and we’re going to go back to making the awesome guns that you actually want.”


The abrupt cancellation will definitely affect the availability of Sig’s new striker fired polymer pistol the P320 which was in the process of shipping to dealers this week. Inside the Sig factory, CNC machines once dedicated to the production of P238s and Molon Labe 1911s were taken offline, scolded for being naughty, and brought back online to machine slides for new production Sig P229s in 9mm. The real question in this announcement is whether or not the news from Sig will affect the just launched P227, their double stack .45 ACP pistol that rounded out the classic P-series line-up. While not a true classic, it fits within the spirit of the classics, and our inside source reports that it will stay around.

In other news, Sig discontinued all calibers other than 9mm for the P226, P229, and P239. Again, our inside source was quote as saying “These guns were designed for 9mm, and 9mm is just better than .40 anyway.” Additionally, the DAK trigger system has been banned from new production guns, and all P-series pistols will now ship standard with Sig’s Short Reset Trigger. Any plans or references to the DAK trigger have reportedly been taken to the fires of Mount Doom and destroyed by BJ Norris and Caleb Giddings.

Early news of Sig’s plans have been greeted with wide-spread acceptance from the serious shooting community. Noted firearms trainer Rob Pincus was quoted as saying “While I only shoot Glocks these days, it’s about time that Sig dropped those other guns. People want the classics, because the classics are the best. And no more diamond rainbow finishes!”

Sig Sauer CEO Ron Cohen was unavailable for comment.

New Sig Sauer 556xi modular rifles

One of the neat guns we had the opportunity to shoot at SHOT Show was the new Sig556xi rifle platform. A big theme this year with Sig Sauer is the modularity game, and the SIG556xi steps that game up. The trick part of the rifle is that the upper is the serialized part, meaning that lowers can be switched out very easily to accommodate different calibers. We shot two versions at media day: a select fire model chambered in 7.62×39, and a semi-auto model in traditional 5.56 NATO. Both guns were very easy and fun to shoot, and the 7.62 model was easy to control on full-auto.

Caleb with SIG556xi

No word from Sig on when they’ll be available for dealers, and I’d suspect a retail price north of $1200. I’ll keep an eye on that, because it is an interesting rifle. The full press release from Sig follows below.

SIG SAUER® Raises the Bar with the SIG556xi®

NEWINGTON, N.H. (January 14, 2014) — SIG SAUER introduces the SIG556xi, rewriting the standard for modularity, reliability, and performance for the modern rifle platform.

Based on the legendary SG 550, the SIG556xi will change the way military, law enforcement, and responsible citizens look at adaptable rifles. Utilizing the time-tested rotating bolt and adjustable gas piston operating system, the SIG556xi allows operators a choice of caliber, barrel length, handguard/stock configurations and lower receivers.


“The SIG556xi has been designed to be the most modular and easily adaptable, hard-use rifle available,” said Jeff Creamer, SIG SAUER Director of Product Management. “From the furniture to caliber to barrel length to magazine preference, the SIG556xi can be completely changed over in minutes to suit the user’s needs.”

A removable barrel allows the operator to select the necessary length for a given mission. Adding the appropriate bolt, the SIG556xi can be changed to any of three calibers, 5.56x45mm NATO, 300 Blackout, and 7.62x39mm. Users can also quickly change out the non-serialized lower receiver, allowing the use of either AR-style STANAG magazines or rock-and-lock AK-style magazines. The SIG556xi upper receiver is the serialized part, making the lower an easy to purchase part.


Polymer handguards accept all Magpul® light and rail kits, while the aluminum and carbon fiber handguards accept 2”, 4”, and 6” M1913 rails. Barrels are available in 10”, 14.5”, and 16”. Truly ambidextrous, the SIG556xi features an ambi safety selector, magazine release and user swappable charging handle (right- or left-handed). Optional receiver end plates allow for the use of either AR receiver extension tubes and buttstocks or M1913 compatible stocks

Thanks to a redesigned trigger package, the military and law enforcement versions of the SIG556xi are capable of full-auto fire in every caliber, including 7.62x39mm. The Russian lower has been thoroughly function tested with many available AK magazines, including US P.A.L.M.
