When the magazine has been emptied the magazine follower is free to press against the projection on the slide stop, thus forcing the slide stop into the front recess of the slide, thereby locking the slide in the open position and reminding the person firing that the empty magazine must be replaced before firing can be continued. Interesting Facts about the Pistol. (a) Weight 2½ pounds. Trigger pull, about 7 pounds. (b) Rifling, 6 grooves with left-hand twist. The drift due to the rifling is therefore to the left, but this is more than neutralized by the pull of the trigger when the pistol is fired from the right hand. (c) For ranges up to 75 yards the trajectory is very flat and the drift slight, giving the pistol great accuracy. [Illustration: COMPONENT PARTS.] [Illustration: COMPONENT PARTS. 1. Receiver. 2.

(e) To hit a target at ranges over 75 yards it will be necessary to lay on a displaced point above and to the right of target for ranges approximately as follows: _Vertical_ _Lateral_ _Range, Yards._ _Displacement._ _Displacement, right._ 100 ½ yard ½ yard 150 1½ yards ¼ yard 200 3 yards 1 yard 250 5 yards 2 yards (f) The striking energy of the bullet is sufficiently great to surely disable a man by causing a dangerous wound at all ranges up to 500 yards. (g) The pistol has been fired by experts at 25 yards, aimed fire, at the rate of 21 shots (3 magazines) in 30 seconds. Such rapidity is, however, not necessary or desirable in service firing. Accuracy is always the first consideration. Precautions.
