馬卡洛夫手槍
The PB uses an integral suppressor, which, unlike most similar systems, consists of two parts. This allows the pistol to be carried and kept concealed without the front section of the suppressor attached, and for the suppressor to be quickly deployed prior to use. The pistol may also be fired safely without the front section attached, which may be important in critical situations. When fired like this, the PB sounds similar to a regular Makarov pistol. The detached suppressor is carried in a special compartment of the holster, which was designed especially for the PB.
