Dayton OH -(AmmoLand.com)- MKS Supply, LLC, the exclusive marketer for the latest Inland Manufacturing retro military firearm – the famed Ithaca Model 37 combat shotgun.

Manufactured by Ithaca in a joint and exclusive effort with Inland Manufacturing, the Ithaca Model 37 “trench gun” is back. This new, all-American-made combat shotgun is faithful to the original from its bead sight, Parkerized finish, oiled stock, and ventilated hand guard to its hard-to-miss bayonet lug that fits the long 1917 bayonet.

The receiver is CNC-machined from a solid block of steel and features the same military markings as the original. Also like the original, it loads and ejects through the bottom of the receiver.

Charles Brown of MKS Supply, the exclusive marketer for the Model 37 says, “For those who want a mean-looking, authentically reproduced combat shotgun, the new Ithaca/Inland Model 37 will be both fun to shoot and a good-looking, authentic combat firearm once used by our troops in Vietnam.”

Editorial background:

Produced in small numbers during WWII, the Model 37 production stopped in 1945 but enough 37s and other brands of so-called “riot guns” had been made to satisfy civilian and law enforcement needs for years to come. The Vietnam War reignited the need for a combat shotgun and Ithaca started building Model 37s again beginning in 1962. Initially made for the Vietnamese military, the 37 proved very effective in jungle fighting and again was found to be needed by our military so subsequently models like the current Inland/Ithaca version were produced throughout the war.

The Model 37 was generally found with some elite units such as Navy SEALs and Army Green Berets. The Model 37 was especially handy for Marine Corps combat medics (Navy medics) and others in support roles on the battlefield – where quick, fight-stopping high-hit probability shots and total reliability were critical while the operator performed his primary mission task.

Out of production since 1975, the Model 37 is now back and every bit as mean-looking and effective as it was in the jungles of Vietnam, where it was effective to 75+ yards with 000, 00, and #4 buckshot, slugs and even flechette rounds (to a lesser degree). The Model 37 has proved to be a serious fight stopper in all out combat since WWII and now again is available to firearm aficionados and those wanting a piece of firearm history.

I bought my Ithaca M37 Defense shotgun tw years ago. I have owned many Ithaca Model 37 shotguns over the last 40+ years and I can tell you the guns being made out of Upper Sabdusky, OH are probably the best guns the company has ever made. Mine has to 20″ barrel, 8-shot magazine and synthetic stock. I paid $610 for mine new.

I played with one yesterday at the local gun store. Fit and finish were excellent, and full figured walnut was used. Yes it is a replica, and it is not cheap. Quality black guns are going for over $2000, and they aren’t collectible either. I checked some recent sales of arsenal re-furbished units used in the Nam. They were going for over $6K. $6K is probably OK, if you are using money that is only earning 5/10th of a percent interest in the bank, as these will rise a demand increases. The problems with the originals, is that because of… Read more »




Now that I see the finished product, I think this is a $600 gun. It is really nothing more than a parked M37 with a repro adapter on it. They did not really do a good job of duplicating the original.

That being said I repeat

A real one costs in the $20K range. All you guys posting about $400 trench guns bought fakes. They only made 1422 of them, and around 12 of them are known to exist in the US.


Would I like to have one of these? Yes, but not at over a grand. Will it slam fire? I’m told yes. So will a Win 97. I would like it as a new model piece of history, just as I would like a Colt New Model Army, Win 73, BAR, and a Sharps 45-110 (or even 45-70). The price for the new models of all these are meant for collectors, re-en actors, or serious history buffs, not the common man. I’ll keep my Rem 870s running. I’ve yet to find a place on them, (wood, newer vented ribs, and… Read more »

And original WWII Ithaca Trench gun in good to excellent condition will bring nearly $20,000, NOT $2000.
A Viet Nam Issue (which is really what this gun appears to copy) in excellent condition will bring somewhere near $5000, maybe more.
These are exceedingly rare.

I will be buying one of these.

D. Denson

I agree . I’ve always wanted one of the trench shotguns. Now that Inland and Ithaca have collaborated to bring these back I will be purchasing one. I don’t fret over the cost of this versus that etc. If I want it I buy it period ! When my National Guard MP unit deployed to Iraq in 2003 we received the Mossberg 500’s And 2 metal case containing model 12 Winchester trench guns !!!! Don’t know how these came about probably stored in some warehouse until they were shipped to us. They were in mint condition these were slam fire… Read more »

Original M37 could be slam fired, from what I understand. Will this new version also allow this?

Devereux Earl

Will the new Ithaca trench shotgun be able to slam bam ?

Bob Sadtler

Will they be making duckbill attachments too?


I would like to have one, but I wouldn’t pay more than $500 for it. This model is way overpriced at $1239. The only thing driving up the value of the originals is their rarity, not that they’re the perfect trench gun, & this gun is NOT an original. By way of comparison, I have an original WWII US marked M37 riot gun (not a trench gun) that I bought a few years ago for only $700.

i just got through refurbishing on of these original trench guns they are a nice gun but not over a 500 dollar gun at the most


There is not one word about that model 37 shotgun, on either inland or mks, website. why waste our time with this story.

Gun writers would boil their own children for a free handout gun from a mfg.

Waste of space.


$1300.00 FOR FAKE HISTORY, Why be a pretender for that price. Not practical for anybody but a rich wanabe. $1500.00 for a Benelli M4 and you have the best tactical shotgun anybody would be happy to have!! Bayonet charges were over rated method of suicide.


Bayonets made it more difficult for prisoners to grab the barrel of a gun. A combined bottom loading ejection and loading port makes for one less hole in the gun for sand and mud to get into the inner workings. I guess we will have to disagree on Benelli vs. Ithaca, but I’ve used Ithacas (and other shotguns) in the marshes, fields, and woods for almost 40 years, so I’m going on more than reviews and conjecture…maybe you are too.

Inland is focused on making perfectly working Quality reproductions of the original firearms used by our hero’s in the military, not selling mass quantities of cheap imports- the Model 37 is made by Ithaca right here in the USA using 100% American materials/parts/labor and most understand the built in value of this historic product not available for the last 40 years. Just like the originals the new M-37 will last decades, there will be only aprox 500 made in 2016, we have had the M-37 at several consumer and industry shows and the interest is very positive, when you see… Read more »


Cam: An original is one way to go but you’ll be shelling out 2 grand or better.


I can understand why a collector could be willing to part with $2K for an original with the duckbill, but this repro doesn’t have any real value except as a wall hanger. I wouldn’t go duck hunting with it, and there are much better, cheaper options for a home defense gun.


There may be shotguns that are cheaper, but not better. I have owned pump shotguns made by Remington, Winchester, Mossberg, Browning, Savage, and Ithaca. The Ithaca just edges the Browning, in my opinion while the others lag far behind. My uncle’s M37 bought in 1960 is just as slick and tight now as it was in the gun shop 56 years later…and no plastic or aluminum


Way over priced Why????


I might pay $500, might, but a benelli supernova tactical would most likely get my cash if i wanted a pump. If I want to buy a piece of history I would buy a real original pre 1975, not a copy that will depreciate.
Make some improvement in the design. Put a 3.5 inch receiver with a 3 inch chamber to speed reloads. I guess if you don’t have the capacity to build a lot and want to keep quality up, trying a collector angle may pay the bills but rarely did anyone get rich playing it safe.
