The TOZ-34 is an over/under style hunting shotgun designed by N. I. Korovyakov and V. P. Ochnev in 1965 for TOZ (Tulsky oruzheiny zavod, or Tula Arms Plant) in Tula municipal district, Russia. It's affordable price and high damage output make it a popular weapon for rookies around the Zone. It also has the ability to unload both rounds almost instantly.
The Hunting Rifle is one of the first seen and most common weapons in the entire game. It is similar in use and performance to the Sawn-off dbl-barrel; it trades slightly lower maximum potential damage and handling for a sizable increase in accuracy and range. It uses all forms of 12 gauge ammunition (shotgun shells, slugs, darts), and carries up to two rounds at a time. It is an extremely cheap (most pistols are worth more) and a common weapon.
As an early game weapon it is quite accurate and dependable when firing slug and dart rounds at short to medium range, provided the weapon's iron sights are used correctly and the operator adjusts for bullet drop.
When fully upgraded, the Hunting Shotgun is amazingly accurate. The only drawback being not able to use buck shot, however the accuracy with slug shot or dart shot overpowers this drawback, although you can prevent this by not installing the "Threaded barrel" upgrade but note that this will limit the gun's full potential.
Generally speaking, much better shotguns can be obtained from dead stalkers (Chaser 13), found in stashes (SPSA14) or ordered from Nimble (Carabiner, Eliminator), and even the sawn-off shotgun is more efficient with pellet ammo. It is not without its niche however – if the player likes the 12x76 Slug, Hunting rifle has best accuracy rating of all the shotguns, which can be further dramatically increased with the Tier 3 rifled barrel upgrade; the upgrade also increases bullet velocity by 100m/s. While the two-bullet capacity is a downside, it can fire from both barrels at once, putting it above Lynx in burst damage. Ultimately, the biggest problem with "TOZ sniping" is the lack of attachable scope which means the player needs a good eye and a steady hand to use it effectively, as the long reload time will be unforgiving to any mistakes.
