   ORIGINAL MAUSER AUTOMATIC
SINGLE- AND MACHINE-FIRE PISTOL
CAL. 7.63 mm (0.300")

Shown with 10-round magazine (left) and 20-round magazine (in place),
in machine fire mode, holster attached, safety off, ready to open fire.

The Mauser-Werke have now placed on the market under the designation Original Mauser Single- and Machine-fire Automatic Pistol, cal. 7.63 mm. (0.300) a new autoloading pistol which can function at will as an ordinary semi-automatic (shot-for-shot) arm, or by the simple motion of a change-over lever on the side as an

ALL-AUTOMATIC QUICKFIRER

embodying the further eminently practical novelty of alternative methods of loading on the clip and detachable magazine systems.

In its essentials the new arm is identical with the universally-known and famous Stan dard 10-round Mauser Automatic Pistol, cal. 7,63 mm. and is the same masterpiece of design and workmanship which has assured the sweeping success and unique reputation of its older brother throughout the entire world. Those interested are referred to Special Catalogue, Be - 2 P. of the Standard Model.

In particular, the new arm, like the old, is distinguished by the absence of all screws and pins from the working parts and their entire enclosure in the body, where they are fully protected against the action of corrosive gases, dust, mud and snow. The chief parts subjected to specially severe stresses have been greatly reinforced, and the weapon stands up without reserve to the intense and racking stresses developed in automatic fire, in which the shots follow each other with machine-gun rapidity. The unsurpassed solidity of design and execution afford a positive guarantee for absolutely uniform and sure functioning in continued automatic fire.

In brief, the new model is an absolutely first rate, unconditionally reliable automatic arm, fulfilling to the last iota the most exacting desiderata which a responsible war, gendarmerie, police or customs department can demand in a weapon for the equipment of its officers and subordinates.< /font>

PISTOL WITH 10-ROUND MAGAZINE
Bolt closed, hammer down and safety "off"
in normal (single-fire) mode.

Single or automatic fire is obtained at will by the simple motion of a switch (change-over lever) located on the left hand side of body. The switch is locked in its working positions by a spring stud which prevents accidental derangement.

When th e pointer of switch is opposite letter N on body, the arm is in semiautomatic (single-fire) adjustment, requiring a fresh pull of trigger for each shot. Releasing switch by pressing in stud and turning until pointer is opposite letter R, the adjustment changes to full automatic delivering a burst so long as trigger is held back: quick relea se of trigger stops the fire, thereby enabling the delivery of short bursts at will.

Rate of Fire. Including the necessary time for changing magazines, the practical rate of continued automatic fire is about 280 rounds per minute.

Equipment. The pistol is regularly supplied with a 10-round magazine, for which a large, 20-round magazine can be exchanged at will. Spare magazines are carried in leather pouches on the belt.

• The 10-round magazine is the rule for single fire, the arm being used as a handgun or with butt at will.

• For automatic fire, the 20-round magazine is preferable as it enables a greater number of short bursts to be delivered before having to reload. On account of the extreme rapidity of automatic fire (15 to 16 rounds a second) the pistol should then always be issued with butt, and rested on some solid object whenever possible, in order to obtain satisfactory fire effect.

Changing magazines is exceedingly quick and sure. Pressing magazine catch on right hand side of body just in front of trigger guard releases the empty magazine (Fig. 9), when the full one, pushed right home, snaps into place.

To load. Cock hammer. Retract bolt fully (Fig. 5), in which position it is retained by hammer. Push full magazine right home into body till click is heard. Ease hammer slightly, releasing bolt, which immediately closes, carrying topmost cartridge into chamber.

Pistol is now ready to fire. On firing the last cartridge, bolt is automatically held in "open" (rearmost position), leaving the arm immediately ready to reload.

Recharging magazine without removing it from pistol is effected in the well known manner by the Mauser clip (Fig. 6), when it is not desired to exchange it for a fully charged duplicate.

Unloading. Remove magazine: then retract bolt gently until any cartridge which may be in chamber drops out. I is most important that this motion shoddy invariably follow removal of magazine for any purpose whatever, thereby preventing any possibility of accident from the "forgotten" cartridge. Then release bolt by slightly easing hammer, and lower latter by pulling trigger.

The pistol is fitted the new Universal safety lock, which realizes the following novel combination of functions requiring the use of thumb of pistol hand alone: Permits arm to be node "safe" or "ready" whether cocked or uncocked, loaded or empty. When "on," hammer is released without the slightest risk by s imply pulling trigger. Provides positive safety against accident during loading or unloading, whence its name.

Operation. To make arm safe, push safety lever upwards until vertical (Fig. 7), when the letter S ("safe") appears over wall of body. To make ready, pull lever down until horizontal, the letter F ("fire") then similarly indicating immediate fire readiness. Note when operating safety that the lever must be moved over up or down until it clicks audibly into its end positions.

Accident-proof loading and unloading. Make "safe." Cock hammer. Lower safety lever until midway between "on" and "off" positions (letters S and F both in sight). Hammer then remains locked by sear, so that no possible carelessness, bungling or unintentional pulling of trigger can discharge the arm. It is thus positively accident- and foolproof.

Ordinary Stripping "A" (for cleaning)

1. Removing Magazine (Fig. 9)
To remove Magazine, press magazine catch stud 12526 just forward of trigger guard with forefinger of pistol hand. Take out magazine. Before going further see if a cartridge remains in chamber and eject same.

2. Removing Working Parts from Body (Fig. 10)
Cock hammer 13393. Press muzzle of pistol on table with left hand. Raise retaining latch 13401 with clip cleaning rod or similar object, releasing body, which then strip off towards muzzle.

Fig. 11a	Fig 11b

3. Parting Lock and Barrel Assemblies (Fig. 11a)
Hold barrel assembly 13 396 in left hand, rearsight downwards. Grasp side lugs W of lock frame with right hand and pull upwards, parting lock assembly from locking block 11971. Lift off locking block as shown in Fig. 11b.

4. Stripping Barrel Assembly (Fig. 12)
Holding barrel assembly with rearsight downwards as before, press cleaning rod into slot of striker 1904 firmly forward and give ¼ turn to right (clockwise). Striker and retractor spring 11910 now project slightly from rear face of bolt and can be drawn out. Press closing spring abutment 11987 towards muzzle and remove from receiver. Bolt 12455 with closing spring 10458 can then be taken out. The arm is now dismounted into its chief components for cleaning.

1. Remounting Barrel Assembly
Insert closing spring 10458 into bolt 12455 and enter both (extractor upwards) into receiver. Compress closing spring with cleaning rod until abutment 11987, boss forward, can be inserted from right. Insert striker 11904 with retractor spring 11910 into bolt, press striker firmly forward with cleaning rod and give ¼ turn to left (counter-clockwise).

2. Replacing locking Block 11971
Lay block, hook towards muzzle and locking lugs towards bolt, over lug of receiver and turn into position by reserve motion shown on Fig 11b.

3. Recoupling Lock and Barrel Assemblies (Fig. 13)
First ascertain if catch hook 13398 is in "disconnected" position (upper limb forward), if not, push it as far forward as it will go (III, Fig. 15a), at the same time cocking hammer. Lay lock assembly on locking block 11971 so that hook of block lies forward of coupling 11994, and tooth of lock frame rests on rearward tongue of locking block. Press lock frame and barrel assembly firmly together (shown to larger scale on Fig. 11a), until hook of locking block engages with coupling.

4. Replacing Working Parts in Body (Fig. 14)
First ascertain that catch hoo k disconnector 13405 (located inside body on right hand wall) has not come our of its seating during handling and is in gear with the stud on pivot of switch; the latter must then move to and fro freely. Take united barrel and lock assemblies in right hand, pressing them lightly together, and slide into body until retaining latch 13 401 locks into place. Lower hammer 13393. Push magazin in e into body until its floor makes contact with body and magazine catch snaps audibly into engagement.

Further Stripping "B"

 HOLSTER BUTT (Fig. 16)

Fig 16

The wooden holster for carrying the pistol also forms a butt attachable to the grip, so that the weapon can also be used as a carbine, its use is indeed essential for effective machine-fire. The additional steadiness of a shoulder arm also reduces the "spread" of fire, a factor of special value when firing at longer than ordinary ranges.

The butt is attached by entering tongue of shoe into T-slot of pistol grip and pressing home until catch snaps into place. After releasing, catch butt can inversely be slipped off pistol grip.

 CARE OF PISTOL

The primer composition and nitro powder residues promote the formation of rust, rendering immediate cleaning of bore after firing (even of a single cartridge) essential to the conservation of the arm. This is easily effected by retracting bolt and wiping out bore from muzzle with a patch on cleaning rod. After this preliminary wiping, the nitro residue produce a slight film of rust which is easily removed by further cleaning with "Mauserol."

If much firing has been done, strip arm as described under "A". Then clean barrel from breech, so as to avoid any wear of bor e at muzzle, and consequent loss of accuracy, also cleaning and oiling lockwork. Further stripping "B" is only occasionally necessary.

If the arm is to be put away for a considerable time, clean all parts thoroughly and lubricate more freely.
