History

 The High Standard Model 10 is a recoil operated, semi-automatic shotgun that was manufactured by the High Standard Manufacturing Company of Hamden, CT. It is easily recognized by its bullpup design, rotatable shoulder stock, and integrated flashlight.The basic design of the Model 10 shotgun was developed in the late 1950s by Alfred Crouch, a Santa Monica, CA police sergeant. Crouch's goal was to create the ultimate entry shotgun for SWAT and tactical units. His original design used a modified Remington semi-automatic shotgun.

In the mid 1960s, Crouch sold his design to the High Standard Manufacturing Company, who used their Flite King shotgun as the basis for the first model, the 10A. The Flite King was modified by replacing the stock, relocating the trigger assembly, and fitting a three-piece plastic shell around the receiver and first half of the barrel. The rearward piece of the shell provided an attachment point for the rotatable shoulder stock. The lower piece of the shell provided the grip. Since the trigger assembly was moved forward to accommodate the bullpup design, a rod that connected the new and original trigger locations was used to allow minimal modifications to the original Flite King receiver.

Although the standard capacity of the Model 10 is 4 cartridges, there was a magazine tube extension available which would increase the capacity to 6 cartridges.

On the early model, the 10A, the upper plastic section also housed the built-in flashlight and carrying handle.

The later model 10B was improved with a left-hand charging handle, flip-up front sight, and utilized the new flashlight mount/carrying handle mounting block (which doubles as the carrying handle mount) as the rear sight. The "Kel-Lite" branded flashlight can be removed, as it is attached to the aforementioned mounting block.

 The HS-10 is available in Zombies from the Mystery Box. It has medium range and decent power. When upgraded, it becomes the Typhoid & Mary, giving it the Dual Wield attachment.

Unlocked after purchasing all other shotguns, it is unlocked at level 24. The HS-10 has more damage than the Spas. Despite being the last shotgun unlocked, it has a relatively small magazine size meaning reloads are constant, and combined with a moderate range, the player could spend more time reloading it than firing it, making Sleight of Hand a good choice to decrease reloading time. Dual Wield also substantially increases the size of the cross-hairs, making it a rather poor choice of attachment, unless the player equips Steady Aim to tighten the cross-hairs, effectively increasing its ability to hit targets. The weapon starts with only 12 reserve shells and so Scavenger is also a good choice to get more ammo.
