As the Classified weapon of the Shotgun class, it is unlocked anytime after level 24, and costs 2000.

The HS-10 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 alsosubstantially increases the size of the cross-hairs, although Steady Aim will tighten the spread of any shotgun, increasing the chance of a one-shot kill. However, the use of Steady Aim without the Dual Wield attachment increases the one hit kill range noticeably. Still, even with the use of Steady Aim and Dual Wield, the cross-hairs are quite large. The weapon starts with only 12 reserve shells (although doubled if the Dual Wield attachment is equipped, and perhaps with greater efficiency with Steady Aim selected) and so Scavenger is a useful perk to replenish the low amount of ammo or Lightweight to get closer to your enemies faster to spray them down. However it should come down to personal preference to having steady aim over sleight of hand. Sometime the spread can be very preferable.

Sleight of Hand is a very useful perk as it halves the time spent reloading that comes with the HS-10's small ammo capacity, however many players choose not to sacrifice Steady Aim'saccuracy bonuses. The Warlord perk, though, is useless, as the only attachment for the HS-10 is Dual Wield.

It is very similar to the SPAS-12 shotgun, but with better spread when ADS, a better iron sights with a slightly higher rate of fire and a faster initial reloading speed, especially if Dual Wield is used. However, the SPAS-12 has an 8 shell capacity, double that of the HS-10's, and starts off with 8 more shells also.

With the Dual Wield attachment (the only non-secondary or SMG to have it), the player reloads both shotguns with 4 shells at once, relatively quickly, making Sleight of Handunnecessary.
