The High Standard Model 10 shotgun is a gas-operated, semi-automatic, tubular magazine-fed bullpup shotgun. The design was developed in the late 1950s by Alferd Crouch, whose goal was to create the ultimate entry shotgun for SWAT units. The original design used a modified Remington semi-automatic shotgun.

Design detailsEdit

In the 1960s, Crouch sold his design to High Standard Manufacturing company, who used their Flite King model as the basis for the first model (Model 10A). It featured a rotatable shoulder stock, a built-in flashlight, and a carrying handle.

The 10B model was improved with a left-hand charging handle, a flip-up front sight, and a new flashlight/carrying handle mount. The flashlight is now removable.

All models of the Model 10 have 4-round tube magazines by default; 2-round extensions are available, for a total of 6 rounds in the magazine (plus one in the chamber).

The most common problem was failures to cycle correctly. The weapon was only to be used with magnum 12-gauge cartridges to guarantee function, but even these did not render 100% function. The trigger (as with most bullpup designs) was also less than desirable. Additionally, it was unsuited to be fired by left-handed users, as the shells were very forcefully ejected to the right, which could potentially hit and injure the user. Usually, there will be a warning label on the right side of the weapon saying "CAUTION - DO NOT SHOOT FROM LEFT SHOULDER".
