The Handkanone is a dedicated crowd-control sidearm that fires a single, very powerful rocket. It offers tremendous damage for a pistol (with its damage-per-shot only exceeded by a few of the pistols) and deals this damage over a moderate area.
However, this high damage comes at the expense of many drawbacks. The Handkanone is by far the heaviest pistol in the game, with a weight comparable to the Tempest shotgun, and only has a single-shot clip with slow re-fire rate, which gives it much clumsier handling than its compatriot pistols.
The Handkanone's nature allows one to experiment somewhat with augmentations, but in serious usage general guidelines remain. Deadly and Race Modded are always viable options, as is Adaptive.
As with all weapons in SAS 4, the Handkanone offers two permanent additional inventory slots and 50% more experience, both Mastery and standard, when enemies are killed with it. Augmentation and resetting of augmentations are also completely free of charge. It costs 80 NK Coins to buy. It also happens to be the only non-rocket launcher weapon manufactured by Teknoboom, though it still fires explosives.
The Handkanone's name translates to "hand cannon", a term often used to describe particularly large and powerful handguns, such as Desert Eagle .50.
The Handkanone cannot be augmented with capacity nor overclocked (semi-auto). However, the level 3 pistol mastery will still add one rocket to the Handkanone, resulting in a capacity of 2.
Though semi-auto, the Handkanone was initially said to be full-auto in the purchase screen.
