Although AR-15s are all the rage in gun circles right now, this hasn’t always been the case. It wasn’t long ago that the tactical pump shotgun was the mainstay of law enforcement throughout the country and was still being used fairly often by the military. Yet even with the popularity of the AR-15s, the shotgun still has legions of fans and one in particular is so popular that Inland Manufacturing made the decision to manufacture a replica of it — the famed M37 Ithaca Trench Shotgun.
Inland teamed with Ithaca Gun Company to create the 12-Gauge recreation of a weapon the U.S. Navy Seals depended on in Vietnam. The point man of the SEAL team would carry the Ithaca M37 because of the formidable 12-gauge caliber rounds it could unleash at point blank range in the dense jungle.
Ithaca uses their 18-inch barreled Defense Gun with its standard bottom feeding and ejection port as the foundation for the M37 Trench Shotgun. Then by using Computer Numerical Control (CNC) milling, the shotgun undergoes three modifications.
The first change is the replacement of the Defense Gun’s 18-inch barrel with a 20-inch version of the original, complete with beaded sight. The next modification is a bayonet mount, which also acts as a heat shield. Although no bayonet is included, the addition of the mount/shield provides a definite boost to the Inland M37 Shotgun’s cool factor. The final modification is the replacement of the Defense Gun’s rubber recoil pad with a military-style grooved buttplate.
The M37 Trench Shotgun is very sharp-looking with rich oil-finished walnut stocks that could match up to many of today’s most expensive guns. The modifications not only provide an aggressive tactical look, but help increase the accuracy of the shotgun.
Author Scott W. Wagner explains how the modernized M37 Trench Shotgun improves overall efficiency for the shooter in his article “Inland Manufacturing 12-Gauge M37 Trench Shotgun: A Historic Reproduction Ready for Duty” at USConcealedCarry.com:
“The extra two inches of barrel and the weight of the heat shield and bayonet mount impart more weight up front, which helps keep the muzzle locked on target for rapid-fire shooting. “ (Read more at USConcealedCarry)
During range testing, the Inland M37 proved itself combat ready. Using a variety of ammo, the Trench Shotgun was consistently true to the point of aim and at a distance of 30 feet, four-inch groupings of eight pellets were the norm.
If this weapon has piqued your interest and you would like to purchase a working recreation of one of the workhorses of Vietnam ground forces, be prepared for sticker shock. The MSRP on the Inland M37 Trench Shotgun is $1259. However, you can rest easy knowing that you are the proud owner of not only a great shotgun from a historic standpoint, but an excellent modern home defense weapon.
