FOREWORD
This manual is published for the information and guidance of
personnel whose duties involve the use, maintenance and repair
of the Ml0 SMG and the Ml1 SMG. Disassembly, assembly, cleaning and minor repairs may be undertaken in the field.
In all cases where the nature of the repair or adjustment is beyond
the scope of facilities of the unit, the Manufacturer should be informed in order that trained personnel with suitable tools and
equipment may be provided.
1. INTRODUCTION
The Ingram Model 10 and Model 11 represent a significant break
through in compact submachine gun design. The Ml0 is available
in 9MM Para and .45 ACP calibers, the Ml1 in .380 ACP caliber.
Both Models are light in weight, durable steel construction and
easy to fire, either semi-automatic or full automatic.
The compact size of the Ml0 makes it especially suitable for
tank crews, gun and mortar crews, etc., and its selective fire
capability makes it an excellent weapon for police use.
The addition of a noise suppressor further enhances the performance, reducing the noise and eliminating muzzle flash.
The weapon operates on the straight blowback principle and is
magazine fed.

2. CONSTRUCTION
The weapon consists of the foliowing major components:
Barrel, Receiver, Bolt, Frame, Firing
Mechanism, Magazine, and Extendable Stock
A sling swivel is attached to the barrel and receiver assembly.
The front end of the barrel is threaded to accept a suppressor.
The receiver is fitted with a fixed front sight and houses the bolt,
recoil spring, buffer and ejector rod. The frame carries the receiver group, trigger mechanism, magazine housing, stock guide,
and safety assembly.
The trigger mechanisms consist of sear, sear spring, selector
lever, retainer, trip, trigger, trigger pin, trigger spring, and disconnector.
The stock is designed to telescope into the frame when not in use
thereby reducing the overall size of the weapon.
The bolt assembly on the Model 10 and Model 11 is fitted with
a cocking handle. Both models have fixed firing pins. The ex
tractor on the Model 10 operates on the leaf spring principle while
the Model 11 utilizes a compression spring.
The magazine for the Model 10 .45 ACP and Model 11 380 ACP
caliber are both of the double column single position feed type,
while the Model 10/9MM Para caliber is of the double column
two position feed type.

I. Firing the Submachine Gun
As the bolt is moved back to the cocked position, the recoil spring
is compressed and the sear engages the sear notch of the bolt.
When the trigger is pressed, the sear releases the bolt, which is
driven forward by the recoil spring. During this forward move-
ment, the bolt strips a cartridge from the magazine into the
chamber. The bolt continues forward and fires the cartridge.
When the cartridge is fired, the chamber pressure forces the
bullet out of the muzzle of the barrel. At the same time, this
pressure overcomes the forward movement of the bolt and starts
it to the rear. By the time the bolt and empty case have moved to
the rear far enough to open the rear of the chamber, the bullet has
left the barrel, and the chamber pressure has diminished. (In the
submachine gun, the chamber pressure is relatively low and the
bolt is relatively heavy; this eliminates the need for positive locking and unlocking.) During the rearward movement of the bolt, the
empty cartridge case is extracted and ejected, the recoil spring
is compressed and the top round in the magazine moves up
against the lips of the magazine. The rearward movement of the
bolt is stopped by contact with the buffer plate.
J. Malfunctions
Malfunctions are usually the result of worn parts or improper care
of the gun. A knowledge of how the gun functions enables the
user to classify and correct the malfunction. Listed below are the
types of malfunctions which might occur.
1. Failure to Feed. The top cartridge in the magazine is not po-
sitioned up and in front of the bolt. Most malfunctions of the
submachine gun are failures to feed caused by a defective or
dirty magazine.
10
2. Failure to Chamber. The top cartridge from the magazine is not
seated in the chamber.
3. Failure to Fire. The cartridge is chambered but does not fire.
4. Failure to Extract. If the cartridge fires, the chamber pressure
will normally push the empty cartridge case out of the
chamber. If the cartridge case is not completely removed
from the chamber and the bolt is retracted, then there is a
failure to extract. This malfunction seldom occurs.
5. Failure to Eject. The empty cartridge case is not ejected from
the weapon.
6. Failure to Cock. If the bolt is retracted and is not held by the
sear, or if, during firing, the bolt does not move to the rear
far enough to clear the top cartridge in the magazine, the gun
fails to cock.
11
Common Malfunctions.
The two most common malfunctions are:
1. Failure to feed-usually caused by a defective magazine.
2. Failure to fire-usually caused by defective ammunition.
Causes of Malfunctions. The following chart lists common causes
of various malfunctions and corrective action.

4. STRIPPING AND REASSEMBLING
The Model 10 and Model 11 have been designed so that no special
tools are necessary in order to’strip or reassemble the weapon.
Stripping
Before starting to strip the weapon remove the magazine and
check the barrel chamber by looking through the EJECTION
PORT to make sure there are no live rounds in the weapon.
A. Field Stripping consists of
1) Removing Upper Receiver (Cock Weapon)
Push receiver pin catch back and remove receiver pin. (See Fig.
10). On alternate configuration where there is no receiver pin
catch, a sharp push on the receiver pin is all that is required for
removal.
Push upper receiver from frame. (See Fig. 11)

the top coil of the spring corresponds with the slope on
the follower.
5. REASSEMBLY
Items are reassembled in the reverse order to the stripping procedure.
17
6. CLEANING AND
It is essential for reliable operation and performance. that the
weapon receive careful maintenance. It should be cleaned at
the end of each day’s firing.
The Gun need only be “field stripped” for this maintenance.
Barrel and Receiver Group Cleaning
A.
Use cleaning rod, patch and solvent. Stubborn residue can
be removed with a bristle bore brush.
B.
Swab bore with patch saturated in solvent.
Use solvent saturated patch and swab inside of receiver to
C.
remove residue.
D.
Use clean dry patch to dry barrel and inside of receiver
group.
E.
Dampen patch with light oil and swab barrel and receiver.
Assembly Cleaning
Bolt
A.
Remove powder residue with solvent and patch.
Wipe all surfaces of bolt to remove carbon. The bolt face
