Military M18 Pistol vs Commercial M18: What's the difference? (Sig Sauer M18 Contract Overrun)

[@treos17]

[@InferiorRifles]

Recoil springs on military guns are stiffer for use with +P ammo, good catch. I forgot to mention it in the video.

The sights on the commercial version are lengthened to accomodate those two mounting screws. I actually just spoke with a rep from Sig yesterday regarding this and the new M17 optic they showed off at SHOT. That M17 is only compatible with the military single-screw mount and is not slated for commercial release at this time. They are working on ways to adapt it, but that won't be a reality for a while.

@@Whiskey.Tango.Actual As I understand it, that sight is a military release only at this time. The rep that I spoke with was NOT happy that they showcased the optic at all since it is not compatible with commercial guns. As I said, they are apparently trying to make a version that can be sold commercially, but it doesn't sound like that will be a reality for some time. The issue is the closed emitter, the low profile that allows it to co-witness with standard height sights, and the overall layout of the sight. I'm sure they will figure it out, but it's going to be a minute....

Commercial version has green night sights on the rear and the military version has orange night sights on the rear. The extractor pin on the military version needs a torx bit to remove where the commercial version does not. Also, the coyote brown PVD on the slide varies. I have seen military versions of the M18 that do in fact have the darker finish like the commercial one in your video. Maybe it's just a batch color variance. I think that there may be more corrosion resistant coatings on the military FCU as well. Not sure about that.

[@spookydookees4399]

Damn, I had to scroll way down to finally read a comment where someone actually knew the differences.

[@rickskeptical]

I found the commercial P320 springs to be heavier than all the M18s we have received. At least providing more tension upon assembly.

[@patrickwolf4505]

Thank you for the video brother, I'm eyeing one of these as my first pistol, currently just own a 716i

[@bishopyourboy8490]

The difference is the military model is fitted with a pretension barrel/slide fitment with accommodating recoil spring assembly. These guns (and top ends) are designed specifically to cycle the MHS ammunition M1152, which is a hot loaded 9MM cartridge similar to what is commonly referred to as “NATO” 9MM.

[@adrnacad3434]

I have the m18 and didn't realize there were differences.

[@paulscountry456]

The Sig Nitron finish is just super tough, the most durable coating that is not a plate I have ever seen.

[@davidcaraballoso2758]

If this is a correctly marked m18, it will have 3 lines on the right side of barrel of markings, plus a p on the under, and on the left side it will also be marked on the barrel. it will also have markings under the slide in the area where the barrel sits. It would be really cool if you could show these markings by taking the barrel out of the slide. Cheers

[@bryanduchane2371]

Love my P320, but have changed out the trigger, grip module, miled the slide to lighten it up, added a gas pedal and had it coated in dark bronze. It doesn't fire anywhere close to what it did when I first bought it, but it's a far better pistol.

[@Moelester692]

Crazy how you have to change everything to make it good lmfao

[@sliturarse]

I notice the lever slide catch is different as well. My M17 slide catch has 2 horizontal lines, where as yours in this video has 3 horizontal lines.

[@tokin420nchokin]

They actually have two different slide catches available in the regular market. The early one was smaller and I believe the made it a little larger for people, however some people preferred the smaller catch depending on how they shoot.

[@R3DNECK]

Those rear sights are notorious for coming off while firing. I'd take it apart and Locktite it before you shoot it.

[@RickNethery]

There needs to be a review of what glue holds these things together best. 👍

[@R3DNECK]

@Rick Nethery's Firearm Channel from what I've heard a little bit of blue locktite will work just fine, and it is what Sig recommends, Sig just "forgot" to do it at the factory.

[@samyousif9028]

The TDP tolerance stack up and the barrel to slide interfaces are much tighter on the contract guns. This was an accuracy requirement by the DOD. Strait from my sig rep.

[@InferiorRifles]

This is correct, Contract pistols have a tighter interface between the Barrel and slide

[@rickskeptical]

Have fired both and saw no difference in accuracy. And most shooting being 25 yds or less anyway. First I have heard of DoD requiring less distance barrel to slide interface as part of contract. Would like to find out if that is in print somewhere. People I work with have been very curious about this very thing.

So the one difference I did find from being issued one and owning one was the recoil spring. The issued ones were circular where it rests on the barrel and the commercial had flat sides (2 short, 2 long) and could only be seated in a certain way when being reassembled. Function and all, the coating on the slide would wear a bit easily and could notice the discoloration when it got warm for the issued ones we had. It wasn't like the very first batches where the controls were also fde color, it was the newer ones where the serials started with TF and the controls were black too

[@johnheater4564]

They are not one peice, the optic that will win the army control is the Romeo-M17 optic and in that the rear sight will go on that.

Supposedly, only a handful of the contract overrun pistols were released to the civilian market. There are M17 contract overruns available with a TF serial number prefix. Remains to be seen if Sig will continue to release more for civilians.

[@spookydookees4399]

For all the comments about the slide not being in battery, it doesn't really matter. It'll still fire that way just fine. If it's really that big of a deal, just swap recoil spring out with the civilian one.

@@InferiorRifles Some M18s have been reported to be developing a ring of metalic buildup in the back of the barrel that actually prevents the round from seating enough to close the action and fire - at least when trying to use military ball ammo.

[@Ideo7Z]

My only real complaint is the way optics are installed on to the slide. The newer Sigs like the AXG Scorpion changed that with a removable plate that is unscrewed from the top instead of the bottom of the slide and the rear sight stays on the gun.

[@heaterfamily]

The optic for this gun doesn’t loos rear sight. Look up Romeo-m17 optic.

Did the contract M18 comes with a +P recoil spring like the contract issue M17? I have a commercial M18 and a milsurp M17 with FDE controls and the slide finishes are the same. I don’t recall if there is a +P spring in the M17 case but the M17 is issued with 2 springs.

All M18s&M17s are on the same assembly line now. At first they kept things separate but now it is all the same.

Source-CO Army National Guard.

[@Cal-Ewok]

So like you said the contractor and commercial sights the biggest difference. Contractor Issued rear sight falls off randomly, reason too much racking the slide back wrongly. I’ve seen while on the range happen several times. The Commercial i’ve not heard any issues, since it’s bolted down as one piece so i’d say commercial is reliable

[@Fugettaboutit]

I thought the actual military issue pistols had all FGDE hardware too, like the trigger and safety lever. Also, isn't there some sort of lock that prevents it from being fully disassembled except by the armorer? Or is the specifically a Marine versions as opposed to the Army version?

[@InferiorRifles]

Only the first “batch” of pistols had FDE controls, all issued guns moving forward will have black controls. The “lock” was an idea that was tossed around but was never implemented.

[@Fugettaboutit]

@@InferiorRifles Ah, interesting, Thx.

[@OttoTheWeim]

Correct. The initial field tested batch had the FDE PVD controls. I have one that was issued and deployed to Iraq. The Army didn’t like how the PVD finish would wear so they asked to have them switched with black controls. The FDE control pistols were then swapped out and put into surplus status and released to the civ market to help recoup costs and as a huge plus to collectors. The rear takedown lock you speak of that was initially pictured in some of the early trial putouts was never implemented and did not go into wide production. Even the Sig employees cannot get hands on one as they were not part of the contract guns.
