2 Grasp recoil spring guide from below, maintaining contact between magazine and guide with thumb pressure from above. Raise guide into alignment and ease to rear. Draw slide slightly rearward to unlock from safety, and ease slide forward off frame (12). Remove recoil spring (11) and guide from frame. Then, remove firing pin (6), mainspring (7), signal pin (21), and spring (22) from slide. This completes field-stripping for normal cleaning.

A semi-automatic pistol small enough to be carried in a vest pocket was designed by John Browning and introduced by the Belgian firm Fabrique Nationale in 1906. The great success of this compact cal. .25 ACP handgun resulted in the development of many other vest-pocket semi-automatic pistols, among them the Haenel-Schmeisser Model I.

Designed by Hugo Schmeisser, the Haenel-Schmeisser Model I pistol was produced by the C. G. Haenel firm, Suhl, Germany. This blowback-operated handgun chambered for the cal. .25 ACP cartridge was brought on the market in the early 1920's. It is generally similar in appearance to the Browning vest-pocket pistol introduced in 1906, but differs considerably from the Browning in mechanical details.

The Haenel-Schmeisser Model I has a spring-driven firing pin as in the Browning vest-pocket pistol, and the firing pin also serves as the ejector. When the pistol is cocked, a signal pin projects from the rear of the frame. There is no ejection port in the slide as in the Browning. Instead, the upper front of the slide is cut away so that the breech is exposed when the slide is to the rear.

Located on the upper left side of the frame behind the grip, the safety is of half-turn type. The magazine cannot be removed unless the safety is engaged on safe. Also, the safety cannot be turned forward to the fire position with the magazine removed from the pistol. This unusual arrangement accomplishes the same thing as the conventional magazine safety of many other semi-automatic pistols, but is slower since it requires operation of the manual safety.

Overall length of the pistol is 4Vi", and weight unloaded is 13 Vi ozs. The magazine holds six rounds. Metal parts are blued, and the black hard rubber grips are checkered and bear the interlocked letters "HS". Workmanship and finish are excellent.

This pistol should not be confused with the Haenel-Schmeisser Model II pistol which is smaller and lighter than the Model I. Both models were discontinued at about the time of World War II. ■
