Stevens M620 (Model 620)

History of Stevens M620 (Model 620)

The Stevens M620 is an improved version of John Moses Browning's earlier M520 series, mainly equipped with a more refined receiver. The gun is available in 12, 16 and 20 calibers and is available in 26, 28, 30 and 32 inch barrel lengths.

Like many other pump action types, the M620 has a five-cup tubular magazine under the barrel assembly. The pump slides are then manually operated by the operator to feed each individual casing into the combustion chamber. Production of this type spanned from 1927 to 1953.

A version with raised, matt ribs was later introduced, called the M621.

In appearance, the M620 follows the traditional design philosophy of shotguns. The stock is well formed, with a one-piece grip (both wooden) leading to a rectangular receiver. The barrel is mounted above a tubular magazine, which is partially encased by a pump slide assembly.

The trigger group hangs below the receiver as usual.

The "Gutter Gun" version of the M620 was used in wartime military acquisitions (primarily in WW2). This variant uses a perforated heat shield on top of the barrel to protect the shooter's hands, and a bayonet mount under the muzzle for close-up work, while being similar to their sporty full-length siblings than, usually equipped with a shorter barrel. In general, however, these versions retain much of the look and quality of the peacetime versions. The "Riot Gun" variant has a similar range, but is intended for security or security purposes, rather than directly fighting the enemy.

These are used with shortened barrels.
