This weapon was developed from the earlier PP-90 submachinegun to have better ergonomics and general handling characteristics. One of the major intents of the design was to have a compact, slim weapon that could be easily concealed. The PP-93 meets that criteria with there even being a holster made and issued for the weapon.
To maintain the compact size of the design, the telescoping bolt has a large percentage of the bolt mass at the front of the receiver above the barrel. There is no protruding cocking handle on the bolt. Instead of a conventional cocking handle, there is a horizontal cylinder under the front of the receiver, sitting at a ninety-degree angle to the line of the weapon. To cock the weapon for firing, the serrated ends of the cylinder are grasped, pressing in the latch on the end of the cylinder at the same time. The cylinder is drawn back to just in front of the trigger guard, cocking the bolt to the rear. When the cylinder is released, it moves back to the front of the receiver under spring tension.
The folding stock is thin and formed from sheet metal. It folds over the entire top of the weapon, merging smoothly with the receiver. When the stock is not used to brace the weapon, it is recommended that a two-handed hold be used to help control full automatic fire. The front of the trigger guard is formed to aid in bracing the weapon with some of the fingers of the non-firing hand. A laser sight and suppressor are both available for the PP-93. Each device can be mounted separately or together depending on the needs of the user. In addition to the safety/selector switch on the left side of the weapon, there is a separate drop or impact safety that locks the bolt if the weapon is dropped or otherwise jarred.
