the breechblock. An illustration of this spring is shown in the drawing from page 216, Mannlicher Rifles and Pistols, Smith, 1947. When the pistol is discharged, as the breechblock moves to the rear and the slide rails travel back in the receiver guides, the cross-beam at the forward end serves to compress the recoil spring against the frame. The lockwork is incorporated on the left side of the frame where it is covered by a removable side cover housing of unusual design, being wrapped around at the forward end and serving also as a cover of the recoil spring. An illustration of this cover is shown in the below drawing from page 218 of the same work. This cover is installed on the frame from the front, and is retained by a spring catch forward of the trigger-guard. The trigger is connected on the left side of the frame to a trigger bar, which, as the trigger is pulled, moves rearward, pushing against the sear tail, which is under the control of the V-spring that serves as both trigger spring and sear spring. The sear nose engages in a notch in the left fork of the hammer (which is external) to provide a smooth trigger pull that is very unusual in an automatic pistol. Mounted on the frame under the right portion of the side cover housing is the mainspring, a heavy V-spring. Its greater arm (lower) engages a notch in the right fork of the hammer to drive it forward when released by the sear. Its lesser arm (upper) continuously presses a cam upward that engages a slot in the under-surface of the breechblock slide when the action is closed. To load the pistol, the breechblock is grasped on the serrated gripping surfaces on the sides, and is pulled straight to the rear. The magazine follower rises to hold the action open, while the cross beam at the forward end of the slide compresses the recoil spring. A loaded stripper clip is inserted into the clip guide in the face of the breech block, and then the cartridges are stripped into the magazine, compressing the spring below the follower. An illustration of this process is shown in the drawing from page 214 of the above-mentioned work. The spring lip at the top of the magazine serves to hold the cartridges.
