This document discusses various types of improvised firearms, also known as zip guns. It provides examples such as zip guns, pen guns, pipe guns, and guns disguised as everyday objects like flashlights, cell phones, cigarettes, briefcases, and keychains. It describes how some of these firearms are constructed in a rudimentary way from available materials to function as a weapon. The document cautions that these improvised firearms can be unstable and pose safety risks due to improper materials or assembly.

2.  IT IS ALSO CALLED AS ZIP
GUN OR PIPE GUN.
 ANY ITEM THAT HAS BEEN
DESIGNED, MODIFIED, OR
DISGUISED TO FUNCTION AS A WEAPON.

FIREARM MANUFACTURER OR A GUNSMITH,AND
ARE TYPICALLY CONSTRUCTED BY ADAPTING
EXISTINGMATERIALS TO THE PURPOSE.

4.  -Zip guns are among the most
commonly improvised firearms.
 -Finding pieces of metal pipe and
tubing like these on a suspect
may indicate the makings of a
zip gun, among the most common
improvised firearms.
 -A handgun round is inserted
snugly into a small diameter tube.
 -That "loaded" tube is then
inserted into a larger pipe, which has
an end cap with a piece of pointed metal
inside it.
 -When a suspect slams the end cap back against a hard surface,
the pointed metal strikes the primer of the round like a firing pin
and discharges the weapon

using 2 pipes and an end- Cap, these
guns usually fire shotgun shells.
 -Place the smaller diameter pipe into
the larger diameter pipe and
forcefully slide it back until the
shells primer makes contact with
a fixed firing pin located inside the
end-cap, firing the gun.
 -They are easy to use and easy to make and can easily fire
around
 12 to15 shots per minute.

7.  -A Mini-Maglite Gun that fires a single .380 or .22
Calibre round.
 -It operates just like the Maglite Shotgun Flashlight.

normal cell phones and has been
completely gutted and replaced
with a rudimentary spring-wound
percussion mechanism.
 -From the outside this “phone” is
indistinguishable from normal cell
phone except it is much heavier.
 -The gun is loaded by twisting the
phone in half.
 -A .22 calibre round fits into the top of
the phone under the screen. The lower half,
under the keypad, holds the firing pins.
 -The bullets fire through the antenna by pressing the keypad from numbers
five to eight, or depressing the “connect” button.

beneath the packet's label.
 -In addition, the packet could be
kept closed, concealing the barrel
but not hindering the operation of the weapon.
 Any brand of cigarette or cigar packaging could be used in
such a device

15.  -Briefcase’s design features a fully
functioning six shot .22 LR revolver
incorporated in the handle of a
professional briefcase.
