appears the regulation applies with equal force to the revolver, if applicable to that weapon.]

135.[9] NOMENCLATURE AND CARE OF THE WEAPON; HANDLING AND PRECAUTIONS AGAINST ACCIDENTS.--The soldier will first be taught the nomenclature of those parts of the weapon necessary to an understanding of its action and use and the proper measures for its care and preservation. Ordnance pamphlets Nos. 1866 (description of the Colt's automatic pistol), 1919, and 1927 (description of the Colt's revolver, calibers .38 and .45, respectively) contain full information on this subject, and are furnished to organizations armed with these weapons.

[Footnote 9: The number refer to paragraphs in the Small Arms Firing Manual, 1918.]

Careless handling of the pistol or revolver is the cause of many accidents and results in broken parts of the mechanism. The following rules will, if followed, prevent much trouble of this character:

(a) On taking the PISTOL from the armrack or holster, take out the magazine and see that it is empty before replacing it; then draw back the slide and make sure that the piece is unloaded. Observe the same precaution after practice on the target range, and again before replacing the pistol in the holster or in the armrack. When taking the REVOLVER from the armrack or holster and before returning it to the same, open the cylinder and eject empty sh.e.l.ls and cartridges. Before beginning a drill and upon arriving on the range observe the same precaution.

(b) Neither load nor c.o.c.k the weapon until the moment of firing, nor until a run in the mounted course is started.

(c) Always keep the pistol or revolver in the position of "Raise pistol" (par. 146, Cavalry Drill Regulations, 1916), except when it is pointed at the target. (The position of "Lower pistol" is authorized for mounted firing only.)

(d) Do not place the weapon on the ground where sand or earth can enter the bore or mechanism.

(e) Before loading the PISTOL, draw back the slide and look through the bore to see that it is free from obstruction.

Before loading the REVOLVER, open the cylinder and look through the bore to see that it is free from obstruction. When loading[10]

the pistol for target practice place five cartridges in the magazine and insert the magazine in the handle; draw back the slide and insert the first cartridge in the chamber and carefully lower[11]

the hammer fully down.

[Footnote 10: TO LOAD PISTOL: Being at raise pistol (right hand grasping stock at the height of and 6 inches in front of the point of the right shoulder, forefinger alongside barrel, barrel to the rear and inclined forward about 30).

Without deranging position of the hand, rotate the pistol so the sights move to the left, the barrel pointing to the right front and up.

With the thumb and forefinger of the left hand (thumb to the right) grasp the slide and pull it toward the body until it stops, and then release it. The pistol is thus loaded, and the hammer at full c.o.c.k.

If the pistol is to be kept in the hand and not to be fired at once, engage the safety lock with the thumb of the right hand.

If the pistol is to be carried in the holster, remove safety lock, if on, and lower the hammer fully down.]

[Footnote 11: TO LOWER THE HAMMER: Being at the loading position at full c.o.c.k.

I. Firmly seat thumb of right hand on the hammer: insert forefinger inside trigger guard.

II. With thumb of left hand exert a momentary pressure on the grip-safety to release hammer from sear.

III. At the same instant exert pressure or the trigger and carefully and slowly lower the hammer fully down.

IV. Remove finger from trigger.

V. Insert pistol in holster.

CAUTION.--The pistol must never be placed in the holster until hammer is fully down.]

In loading the REVOLVER place five cartridges in the cylinder and let the hammer down on the EMPTY CHAMBER.

(f) Whenever the pistol is being LOADED or UNLOADED, the muzzle must be kept up.

(g) Do not point the weapon in any direction where an accidental discharge might do harm.

(h) After loading do not c.o.c.k the pistol or the revolver until ready to fire.

(i) Keep the working parts properly lubricated.

136. POSITION, DISMOUNTED.--Stand firmly on both feet, body perfectly balanced and erect and turned at such an angle as is most comfortable when the arm is extended toward the target; the feet far enough apart to insure firmness and steadiness or position (about 8 to 10 inches); weight of body borne equally upon both feet; right arm fully extended, left arm hanging naturally.

REMARKS.--The right arm may be slightly bent, although the difficulty of holding the pistol uniformly and of keeping it as well as the forearm in the same vertical plane makes this objectionable.

137. THE GRIP.--Grasp the stock as high as possible with the thumb and last three fingers, the forefinger alongside the trigger guard, the thumb extended along the stock. The barrel, hand, and forearm should be as nearly in one line as possible when the weapon is pointed toward the target. The grasp should not be so tight as to cause tremors of the hand or arm to be communicated to the weapon, but should be firm enough to avoid losing the grip when the recoil takes place.

REMARKS.--The force of recoil of the pistol or revolver is exerted in a line above the hand which grasps the stock. The lower the stock is grasped the greater will be the movement or "jump" of the muzzle caused by the recoil. This not only results in a severe strain upon the wrist, but in loss of accuracy.

If the hand be placed so that the grasp is on one side of the stock, the recoil will cause a rotary movement of the weapon toward the opposite side.

The releasing of the sear causes a slight movement of the muzzle, generally to the left. The position of the thumb along the stock overcomes much of this movement. The soldier should be encouraged to practice this method of holding until it becomes natural.

To do uniform shooting the weapon must be held with exactly the same grip for each shot. Not only must the hand grasp the stock at the same point for each shot, but the tension of the grip must be uniform.

138. (a) THE TRIGGER SQUEEZE.--The trigger must be squeezed in the same manner as in rifle dring. (See Chapter VIII, section 6.) The pressure of the forefinger on the trigger should be steadily increased and should be straight back, not sideways. The pressure should continue to that point beyond which the slightest movement will release the sear. Then, when the aim is true, the additional pressure is applied and the pistol fired.

Only by much practice can the soldier become familiar with the trigger squeeze. This is essential to accurate shooting. It is the most important detail to master in pistol or revolver shooting.

(b) SELF-c.o.c.kING ACTION.--The force required to squeeze the trigger of the revolver when the self-c.o.c.king device is used is considerably greater than with the single action. To accustom a soldier to the use of the self-c.o.c.king mechanism, and also to strengthen and develop the muscles of the hand, a few minutes practice daily in holding the unloaded revolver on a mark and snapping it, using the self-c.o.c.king mechanism, is recommended.

The use of the self-c.o.c.king device in firing is not recommended except in emergency. By practice in c.o.c.king the revolver the soldier can become sufficiently expert to fire very rapidly, using single action, while his accuracy will be greater than when using double action.

139. AIMING.--Except when delivering rapid or quick fire, the rear and front sights of the pistol are used in the same manner as the rifle sights. The normal sight is habitually used (see Pl. VI), and the line of sight is directed upon a point just under the bull's-eye at "6 o'clock." The front sight must be seen through the middle of the rear-sight notch, the top being on a line with the top of the notch. Care must be taken not to cant the pistol to either side.[12]

[Footnote 12: The instructor should take cognizance of the fact that the proper aiming point is often affected by the personal and fixed peculiarities of the firer, and if unable to correct such abnormalities, permit firer to direct sight at such point as promises effective results.]

If the principles of aiming have not been taught, the soldier's instruction will begin with sighting drills as prescribed for the rifle so far as they may be applicable. The sighting bar with open sight will be used to teach the normal sight and to demonstrate errors likely to be committed.

To construct a sighting rest for the pistol (see Pl. VI) take a piece of wood about 10 inches long, 1-1/4 inches wide, and 9/16 inch thick. Shape one end so that it will fit snugly in the handle of the pistol when the magazine has been removed.

Screw or nail this stick to the top of a post or other object at such an angle that the pistol when placed on the stick will be approximately horizontal. A suitable sighting rest for the revolver may be easily improvised.

140. (a) HOW TO c.o.c.k THE PISTOL.--The pistol should be c.o.c.ked by the thumb of the right hand and with the least possible derangement of the grip. The forefinger should be clear of the trigger when c.o.c.king the pistol. Some men have difficulty at first in c.o.c.king the pistol with the right thumb. This can be overcome by a little practice. Jerking the pistol forward while holding the thumb on the hammer will not be permitted.

(b) HOW TO c.o.c.k THE REVOLVER.--The revolver should be c.o.c.ked by putting the thumb on the hammer at as nearly a right angle to the hammer as possible, and by the action of the thumb muscles alone bringing the hammer back to the position of full c.o.c.k. Some men with large hands are able to c.o.c.k the revolver with the thumb while holding it in the position of aim or raise pistol. Where the soldier's hand is small this can not be done, and in this case it a.s.sists the operation to give the revolver a slight tilt to the right and upward (to the right). Particular care should be taken that the forefinger is clear of the trigger or the cylinder will not revolve. Jerking the revolver forward while holding the thumb on the hammer will not be permitted.

141. POSITION AND AIMING DRILLS, DISMOUNTED.--For this instruction the squad will be formed with an interval of 1 pace between files.

Black pasters to simulate bull's-eyes will be pasted opposite each man on the barrack or other wall, from which the squad is 10 paces distant.

The squad being formed as described above, the instructor gives the command: 1. _Raise_, 2. _Pistol_ (par. 156, Cavalry Drill Regulations), and cautions, "Position and aiming drill, dismounted." The men take the positions described in paragraph 136, except that the pistol is held at "Raise pistol."

The instructor cautions, "Trigger squeeze exercise." At the command READY, c.o.c.k the weapon as described in paragraph 140. At the command, 1. _Squad_, 2. FIRE, slowly extend the arm till it is nearly horizontal, the pistol directed at a point about 6 inches below the bull's-eye. At the same time put the forefinger inside the trigger guard and gradually "feel" the trigger. Inhale enough air to comfortably fill the lungs and gradually raise the piece until the line of sight is directed at the point of aim, i. e., just below the bull's-eye at 6 o'clock. While the sights are directed upon the mark, gradually increase the pressure on the trigger until it reaches that point where the slightest additional pressure will release the sear. Then, when the aim is true, the additional pressure necessary to fire the piece is given so smoothly as not to derange the alignment of the sights.

The weapon will be held on the mark for an instant after the hammer falls and the soldier will observe what effect, if any, the squeezing of the trigger has had on his aim.

It is impossible to hold the arm perfectly still, but each time the line of sight is directed on the point of aim a slight additional pressure is applied to the trigger until the piece is finally discharged at one of the moments when the sights are correctly aligned upon the mark.
