PPT

The PPT (Pellet Projection Tube) is the "standard police weapon" of the late 22nd century. The PPT utilizes non-lethal pellets as projectiles to temporarily incapacitate a human target. Darien Lambert became an "expert with the pellet projection tube" as part of his law enforcement training at the International Police Academy at West Point on Hudson.

Size
PPT pellets have a diameter of 3.05mm. SELMA posits that for a marksman of Darien Lambert's skill (expert with the PPT), even under less than ideal circumstances, hitting a target with a diameter of 8mm at close range should be relatively easy.

Standard Pellets

 * Blue: stuns a human target for two minutes
 * Green: stuns a human target for three hours

TXP Pellets

 * Red: insertion of TXP into a living target. Pellet injection puts the subject into a coma. Afterwards, a transmission tone can be activated (by SELMA) to temport the subject to TRAX control in the 22nd century. Activation of the transmission tone can be done immediately or can be delayed.

Modular design
The PPT is shown to be a modular weapon system (MWS)

Styles

 * Combat: Two PPTs in a double-tubed over/under combat-style frame are used by a cadet on the shooting range at the International Police Academy.
 * Side-handle baton: a PPT in a side-handle baton frame is carried by Darien Lambert and other members of the police force that breach TRAX control to apprehend Mordechai Sahmbi.
 * Straightstick: a PPT in a straightstick frame with a lanyard is used by Wallace Morgan to incapacitate his victims.
 * Gauntlet: Two PPTs in a gauntlet frame are used by a cadet on the shooting range at the International Police Academy.

Miniature design
The MPPT (Miniature Pellet Projection Tube) is a smaller, and more compact version of the PPT.

Styles
The MPPT Darien Lambert employs is designed to look like a key fob for a late 20th century car alarm. Darien Lambert's MPPT can be loaded with both standard pellets and TXP pellets. The pellet capacity of Darien Lambert's MPPT is never stated but it has on at least one occasion depleted its compliment of pellets and required a reload.

Humans
Standard pellets projected from a PPT are effective on all humans.

Procardians
It is implied that TXP pellets are effective on Procardians, but unknown what effect; if any, standard pellets (blue and green) have on the Procardian physiology.
