- PIPE PISTOL FOR 9 MM AMMUNITION
- A 9 mm pistol can be made from 1/4" steel gas or water pipe and fittings.
- MATERIALS REQUIRED:
- -------------------
- 1/4" nominal size steel pipe 4 to 6 inches long with threaded ends.
- 1/4" Solid pipe plug
- Two (2) steel pipe couplings
- Metal strap - roughly 1/8" x 1/4" x 5"
- Two (2) elastic bands
- Flat head nail - 6D or 8D (approx. 1/16" diameter)
- Two (2) wood screws #8
- Wood 8" x 5" x 1"
- Drill

- PROCEDURE:
- ----------
- 1. Carefully inspect pipe and fittings.
- a. Make sure that there are NO cracks or other flaws in the pipe or fittings.
- b. Check inside diameter of pipe using a 9 mm cartridge as a gauge. The
- bullet should closely fit into the pipe without forcing but the cartridge
- case SHOULD NOT fit into pipe.
- c. Outside diameter of pipe MUST NOT BE less than 1 1/2 times bullet diameter
- (.536 inches; 1.37 cm)
- 2. Drill a 9/16" (1.43 cm) diameter hole 3/8" (approx. 1 cm) into one
- coupling to remove the thread.
- Drilled section should fit tightly over smooth section of pipe.
- 3. Drill a 25/64" (1 cm) diameter hole 3/4" (1.9 cm) into pipe. Use cartridge
- as a gauge; when a cartridge is inserted into the pipe, the base of the case
- should be even with the end of the pipe. Thread coupling tightly onto pipe,
- drilled end first.
- 4. Drill a hole in the center of the pipe plug just large enough for the nail
- to fit through.
- NOTE: Hole MUST be centered in plug.
- 5. Push nail through plug until haed of nail is flush with square end. Cut
- nail off at other end 1/16" (.158 cm) away from plug. Round off end of nail
- with file.
- 6. Bend metal strap to "U" shape and drill holes for wood screws. File two
- small notches at top.
- 7. Saw or otherwise shape 1" (2.54 cm) thick hard wood into stock.
- 8. Drill a 9/16" diameter (1.43 cm) hole through the stock. The center of the
- hole should be approximately 1/2" (1.27 cm) from the top.
- 9. Slide the pipe through this hole and attach front coupling. Screw drilled
- plug into rear coupling.
- NOTE: If 9/16" drill is not available cut a "V" groove in the top of the stock
- and tape pipe securely in place.
- 10. Position metal strap on stock so that top will hit the head of the nail.
- Attach to stock with wood screw on each side.
- 11. String elastic bands from front coupling to notch on each side of the
- strap.
- SAFETY CHECK - TEST FIRE PISTOL BEFORE HAND FIRING
- --------------------------------------------------
- 1. Locate a barrier such as a stone wall or large tree which you can stand
- behind in case the pistol ruptures when fired.
- 2. Mount pistol solidly to a table or other rigid support at least ten feet
- in front of the barrier.
- 3. Attach a cord to the firing strap on the pistol.
- 4. Holding the other end of the cord, go behind the barrier.
- 5. Pull the cord so that the firing strap is held back.
- 6. Release the cord to fire the pistol. (If pistol does not fire, shorten the
- elastic bands or increase their number.)
- IMPORTANT: Fire at least five rounds from behind the barrier and then re-in-
- spect the pistol before you attempt to hand fire it.

- Flat head nail - 6D or 8D (approximately 1/16" (1-1/2 mm) diameter
- 2 wood screws, #8
- Hard wood, 8" x 5" x 1" (20 cm x 12-1/2 cm x 2-1/2 cm)
- Drill
- Wood or metal rod, 1/8" (3 mm) diameter and 8" (20 cm) long
- Saw or knife
- PROCEDURE:
- ----------
- 1. Carefully inspect pipe and fittings.
- a. Make sure that there are NO cracks or other flaws in the pipe or fittings.
- b. Check inside diameter of pipe using a .22 caliber cartridge, long or
- short, as a gauge. The bullet should fit closely into the pipe without
- forcing, but the cartridge case SHOULD NOT fit into the pipe.
- c. Outside diameter of pipe MUST NOT BE less than 1-1/2 times the bullet dia-
- meter.
- 2. Drill a 15/64" (1/2 cm) diameter hole 9/16" (1-1/2 cm) deep in pipe for
- long cartridge. (If a short cartridge is used, drill hole 3/8" (1 cm) deep).
- When a cartridge is inserted into the pipe, the shoulder of the case should
- butt against the end of the pipe.
- 3. Screw the coupling onto the pipe. Cut coupling length to allow pipe plug
- to thread in pipe flush against the cartridge case.
- 4. Drill a hole off center of the pipe plug just large enough for the nail to
- fit through.
- NOTE: Drilled hole MUST BE OFF CENTER in plug.
- 5. Push nail through pipe plug until head of nail is flush with square end.
- Cut nail off at other end 1/16" (1-1/2 mm) away from plug. Round off end with
- file.
- 6. Follow procedures of Section III, No. 1, steps 6 through 11.
- 7. Follow SAFETY CHECK, Section III, No. 1 or No. 9.
- HOW TO OPERATE:
- ---------------
- Follow procedures of HOW TO OPERATE PISTOL, Section III, No. 1, steps 1, 2,
- and 3.
- Section III
- No. 11
- LOW SIGNATURE SYSTEM
- Low signature systems (silencers) for improvised small arms weapons (Section
- III) can be made from steel gas or water pipe and fittings.
- MATERIALS REQUIRED:
- -------------------
- Grenade container
- Steel pipe nipple, 6" (15 cm) long- See Table I for diameter
- 2 steel pipe couplings - See Table II for dimensions
- Cotton cloth - See Table II for dimensions
- Drill
- Absorbent cotton
- PROCEDURE:
- ----------
- 1. Drill hole in grenade container at both ends to fit outside diameter of
- pipe nipple. (See Table I.)
- 2. Drill four (4) rows of holes in pipe nipple. Use Table I for diameter and
- location of holes.

- * Extra Heavy Pipe
- All dimensions in inches
- 3. Thread one of the pipe couplings on the drilled pipe nipple.
- 4. Cut coupling length to allow barrel of weapon to thread fully into low
- signature system. Barrel should butt against end of the drilled pipe nipple.
- 5. Separate the top half of the grenade container from the bottom half.
- 6. Insert the pipe nipple in the drilled hole of container. Pack the absor-
- bent cotton inside the container and around the pipe npple.
- 7. Pack the absorbent cotton in top half of grenade container leaving hole in
- center. Assemble container to the bottom half.
- 8. Thread the other coupling onto the pipe nipple.
- NOTE: A longer container and pipe nipple, with same "A" and "B" dimensions as
- those given, will further reduce the signature of the system.
- HOW TO USE:
- -----------
- 1. Thread the low signature system on the selected weapon securely.
- 2. Place the proper cotton wad size into the muzzle end of the system.
