U.S. Marine Corps Adoption of M18 Underscores Success of SIG SAUER MHS Program

NEWINGTON, N.H.-(Ammoland.com)- SIG SAUER, Inc. is honored to announce that the United States Marine Corps (USMC) is set to adopt the M18, the compact variant of the U.S. Army’s Modular Handgun System (MHS), as their official duty pistol.

“The Marine Corps announcement to put the M18 in service with the Marines is a very exciting development for SIG SAUER, and a true testament to the success of the MHS program,” began Ron Cohen, President & CEO, SIG SAUER, Inc. “The Marine’s procurement of the M18 brings the adoption of our Modular Handgun System full circle, as this means, beginning in 2020, either the M17 or the M18 will be officially in service with every branch of the U.S. Military.”

The M18 is a 9mm, striker-fired pistol featuring a coyote-tan PVD coated stainless steel slide with black controls. The pistol is equipped with SIGLITE front night sights and removable night sight rear plate, and manual safety.

Recently, the M18 successfully completed a MHS Material Reliability Test that consisted of firing three M18 pistols to 12,000 rounds each for a total of 36,000 rounds in accordance with the MHS requirements. Comparatively, the U.S. Army’s legacy pistol was only tested to 5,000 rounds making the test duration for the M18 pistol 2.4 times greater than that of the legacy pistol. In this testing, the M18 experienced zero stoppages despite being allowed up to twelve stoppages. Additionally, the M18 passed a parts interchange test, and met stringent accuracy and dispersion requirements.

“The success of the MHS program is the direct result of the indisputable performance and superior quality of the M17 and M18 pistols, and the commitment and dedication of the men and women of SIG SAUER to those that serve in the defense of freedom,” continued Cohen. “We are very proud, and humbled, to have earned the trust of every branch of the U.S. Military through their acceptance of the MHS program and adoption of the M17 and M18 pistols.”

Currently, the M17 and M18 are in service with the U.S. Army, Navy, Air Force, and Coast Guard. The USMC will begin their acquisition of the M18 pistol in 2020.

It’s a P250 wit ha fancy firing pin. Same piece of carp as the P250.


I care not what ‘pistol’ the military decides to put in our youngsters’ hands. I do care that this just looks like some ‘Back To The Future,’ or Back To The Past move. Even as far back as the 1870’s they had handguns with more energy than the two loads (124/147) our people will ‘attempt’ the last resort of saving their lives. That 147 is less than 400 FPE and the 124 has far less than 500 FPE! I just don’t appreciate that ‘my Marines’ are saddled up with these weak sister “compromises!” The military and civilian law enforcement have… Read more »


Meant to add, that the .45 ACP, in in a +P+ loading, does not reach that 500 FPE level I would prefer our people be able to pack around! Accuracy? I call this my “Mickey Mouse” off-hand group:

Everyone I’ve ever shot in the face with a 9mm has left me the hell alone.


LOL! Excellent; however, you see that video, just today, of that whack wanting to shoot up some federal bldg? Don’t have a clue what those PD boys were shooting the guy with, but appears none got him “in the face,” as he was running and attempting to hide in the parking lot until he finally died out! Lotsa folk believe in and depend on the 9mm, which, if it meets “their” need, is at least NOT unarmed. I’m just too old school, I prefer BIGGER boolets, the BIGGER the animal the BIGGER the boolet – ANY armed animal gets the… Read more »

Has the drop fire been fixed on all these pistols to include future manufacture. There is also the problem of being discharged by a well place hammer strike. Until they are all fixed I would not want to be anywhere near one. I wonder if all military and others exposed to the P320 platform is aware of the problem. Somebody should tell them. A wider training of live grenade procedure should be implemented for this pistol.

I had to send mine in and it came back with no issues. They identified it a couple years ago and have since corrected the issue.


I carried an M9 for over 20 years, in and out of the Corps, could shoot it by memory very accurately. So it was surprising that I consider my Sig a much more reliable handgun.

Why you little whipper snappers the military should never have gotten rid of the 1873 Colt .45. A true soldiers handgun
if it can take down a horse it can take down the enemies of “merica”.
I hope you all realize this comment is dripping with sarcasm. Guess what you get a hole poked into you by
a SIG 320, an M9, a 1911 or a Colt Peacemaker your not going to care that it was fired from a gun you dislike.


Remember one thing-military contracts go to the lowest bidder or to companies that politicians own a lot of stock in.


Allow soldiers and Marines to buy their own sidearms, of their choosing , to save their bacon… that way we can save a lot of money and all the soldiers can be armed.. and they can actually train with it on their own, instead of that vanilla military pistol training…
if I was going to have a Sig it would either be an M11 A1 or a Mark 25..or a BRAND NEW M9 or px4 compact.. I would want a double strike option.. light primer strikes will get you killed..the p320 is..


The p320 is CRAP!!

The SIG TRIGGER HAS ALWAYS BEEN A PROBLEM FOR ME. My H&K P7 trigger is much easier and more comfortable shooting. Several members of my family have Sigs and love them. I have BIG hands.


@Luther Lewis…Apologies in advance…You cite having “BIG” hands. The H&K P7 has a smaller trigger guard opening and the trigger is shorter and more sharply curved than the Sig P320/M17/M18. I had a P7 and sold it off because the trigger and guard opening was too cramped up for me (I also sold off several Glocks for lack of interior space in the trigger guard). I now have 3 P320’s with much more working room than the P7 had and I shoot them better as a result. Now granted, we all have our own very personal reasons for loving or… Read more »
