Why is there so much disdain towards the M9 Bayonet?

It's been said that the M9 borrowed some cues from both the AK-47 Bayonet and the Buckmaster 184.

The following is just my opinion, but I believe the M9 blade should have used the full length tang method of the previous M7 bayonet.
The Buckmaster 184 had the threaded stub tang design to allow a small storage space in it's hollow handle, but why did they go with a similar threaded stub tang for the M9 blade? The M9 handle doesn't have a hollow handle storage space, and it just didn't need to differ on tang assembly to that of the M7.
The M7 is easy enough to disassemble, having only a few screws to remove it's handle scales for the replacement of those scales, (if needed), or for any other required maintenance it may otherwise need.
If it had followed the M7's bayonet tang idea, I think it would have garnered more of a following. Even those that do battoning, would likely feel better about the knife's construction. It would have given it more of that "pry bar" toughness that a lot of bayonets are often known for.

I just collect all sorts of things, so I have one of the olive drab Ontario M9's in my collection, (just as a representative piece of this bayonet model). I am pretty confident that the testing performed on them during their military trials must have convinced some folks that they are indeed tough enough for their basic military job requirements.
And, it sure is a less plain Jane looking bayonet than the M7 is. It's also likely a better tool than the M7 when it's just being used as a general purpose knife. It's wire cutting ability might not be optimal, but it was tested to do that job in a pinch for soldiers, and so I find that to be a pretty cool feature, (of course inspired by the AK-47 bayonet).

New Ontario made M9's can be had new for maybe $100 to $150, but other than it being kinda cool as a collectible, (or as a cool display add on for one's Mossberg 500 A-1, AR-15, and such), there is probably going to be little interest in it outside of that.

As a collectable, if one wants one made by a US Military supplier, I guess the Ontario M9 is one's only choice if buying a new specimen from a vendor.
I know there are some Phrobis/Buck versions that are quite collectable, and some are quite pricey 😱

This is my M9 made by the Ontario Knife Company. It's factory new, not a military surplus specimen.
I don't believe they make their commercially sold M9's any different than their military slated specimens.
Does anyone know if there are any differences, maybe in markings or materials?

I know there have been quite a few M9 offerings that are/have been made overseas by non US Military contractors, and that they can be had less expensively than, let's say, the Ontario M9's, but... I kind'a prefer such things being made by the actual companies that make them for the GI servicemen.

I have talked with a Marine who was in Iraq for the "surge" in 2004-'05. He said that a mounted bayonet seemed to be intimidating to civilians when clearing a building. He also told me that when on foot patrol they were often harassed by dogs. Not wanting to fire a shot, a bayonet would be their less-than-loud option.

I know that some knifemakers have offered a bayonet. I think Zero Tolerance did. Maybe Gerber did too. I have often thought that one of the high-end or premium makers could or should too. A Randall Made off-catalogue option Bowe-bayonet is one thought. A Chris Reeve Green Beret bayonet is another. Any custom knifemakers ever do a functional bayonet?
 
What movie was that (about the Korean war) wherein the American troops were hiding among rocks, running out of ammo, and massed attacks just kept coming in, until their commander shouted "Fix bayonets!"

There is no bad bayonet. Anything pointy at the front end of your rifle can be very useful in a life-or-death situation. Trouble is, rifles are a bit different now from those used in Korea (or even Vietnam.) I reckon mounting a bayonet onto a contemporary AR-15 type of rifle, and using it realistically, will render that rifle totally messed up.
I don't know the movie, but it sounds like Lewis Lee Millett.

Millett's official Medal of Honor citation reads:


Capt. Millett, Company E, distinguished himself by conspicuous gallantry and intrepidity above and beyond the call of duty in action. While personally leading his company in an attack against a strongly held position he noted that the 1st Platoon was pinned down by small-arms, automatic, and antitank fire. Capt. Millett ordered the 3d Platoon forward, placed himself at the head of the 2 platoons, and, with fixed bayonet, led the assault up the fire-swept hill. In the fierce charge Capt. Millett bayoneted 2 enemy soldiers and boldly continued on, throwing grenades, clubbing and bayoneting the enemy, while urging his men forward by shouting encouragement. Despite vicious opposing fire, the whirlwind hand-to-hand assault carried to the crest of the hill. His dauntless leadership and personal courage so inspired his men that they stormed into the hostile position and used their bayonets with such lethal effect that the enemy fled in wild disorder. During this fierce onslaught Capt. Millett was wounded by grenade fragments but refused evacuation until the objective was taken and firmly secured. The superb leadership, conspicuous courage, and consummate devotion to duty demonstrated by Capt. Millett were directly responsible for the successful accomplishment of a hazardous mission and reflect the highest credit on himself and the heroic traditions of the military service

Millett was quite a guy. I spoke with him on the phone once and have his Challenge Coin. https://en.wikipedia.org/wiki/Lewis_Millett#Medal_of_Honor_citation

there was such hope in '86 for the m9

"....the prior M9 bayonet the handle was formed as a separate part, loosely slipped over the tang, and fastened to the tang with a cap screw. That approach is operable with the present bayonet, but is not preferred because of its lower strength as compared with the molded handle design.
The preferred form of the present bayonet construction is much stronger than that of the prior M9 design. The one-piece, integral blade-and-tang configuration, with the stress-reducing features discussed previously, does not have the potential sources of weakness present in many prior bayonet configurations. Elimination of a threaded connection between the blade and the tang eliminates the threaded structure which is a potential source of premature failure under load. Molding the handle to the tang packs the handle material tightly to the tang and eliminates possible looseness of the handle on the tang that can occur when the handle is fastened to the tang with a threaded or other type of connector. Additionally, the present approach is less expensive than the prior approach, because fewer pieces are required and assembly costs are reduced. The corrosion resistance of the unit is also improved...."

Well crap. I wanted a wire cutter not a finger cutter.
 
The M9 is an OK military field knife but its too heavy. They need to find ways to strip it down to where its not a burden to carry. A few years ago I was hanging out with the 2nd Bat of the 75th Rangers. Several of the young guys told me they carried M7 bayonets by choice because they thought they were better fighting knives than the M9. There were also a wide variety of private purchase fixed blades. So much for the claim often made here that all you need is a multi-too.
 
I asked on the Ontario section of the forum about current OKC M9 commercially sold and the Mil Spec contract M9, and if there were any differences between them. One of the guys gave me the following response....

"No difference at all in the bayonets themselves as they are ALL made to milspecs.
The only "difference" is the military contract pieces are shipped in a plastic bag(as per mil spec contract),the commercial ones are shipped in a box.
Hope this helps"
 
I had to come in and share something I find quite funny about a lot of negative reviews I have read on vendor sites concerning something that is not the M9's fault, but actually many buyer's fault.

You see, it's a bayonet, and so it's designed to be attached at the muzzle end of a firearm. The M9 bayonet's main target is to be used on most military M16/M4 rifles and carbines.

One of the most common negative reviews one reads about buyers not being happy with their purchased M9 bayonet, is that it doesn't fit their civilian AR15/M4.
That's because the distance between the bayonet lug and the flash suppressor on one firearm has to be the same distance apart as is found on the Military's 20" barreled M16's and the Military's 14.5" M4's. Otherwise, it won't fit properly without using an adapter of some sort.
And yet, one can read review after review that tries placing blame on the bayonet for not fitting their rifles 😅
 
No distain. Just lack of interest.

Unless you're on active duty and expect to engage in hand-to-hand combat in the "trenches," what's the value of a bayonet these days? :rolleyes:
