The Sil-50 Sonic Pistol, crafted by Pacnorval Defense Systems, Limited, was comparable in size to the DL-44 heavy blaster pistol. Its maximum operational distance extended to 20 meters (or 40 meters when submerged), while its effective range was 10 meters (30 meters underwater). Differing from the Sg-82 sonic rifle, the Sil-50 was engineered to subdue targets without inflicting physical damage.
This pistol emitted a sonic pulse of extremely low frequency, replicating the signals of the target's nervous system. While it was commonly thought that pulse frequency needed adjustment per species, the reality was that a shared frequency was effective against the majority of humanoid species. Though primarily intended for use on Humans, specialized hypersonic frequency chips could be acquired for targeting Wookiees, Sullustans, and Rodians. The Sil-50's incapacitating sonic emission had such a low frequency that human inner ears could neither detect nor perceive it, even though numerous species possessed the ability to hear such ultra-low frequencies. Typically, the Sil-50 was unable to produce lethal shots directly, but a point-blank, full-power blast could be fatal, especially if delivered underwater.
A target struck by the Sil-50's pulse would suffer from severe vertigo, sickness, complete confusion, memory impairment, and the possibility of throwing up. Approximately two seconds after exposure, the target would lose consciousness, remaining in a disabled state for as long as several hours. In many cases, the target would have no recollection of events until regaining consciousness much later.
