Martini Type Rear Hinged Breechblock Action Exploded View

Hammerli Model 103.

By EDWARD J. HOFFSCHMIDT

The free-pistol is designed specifically for precision slow-fire target shooting. It is free of practically all design restrictions, hence the term free-pistol. Choice of barrel length, sight radius, trigger pull and grip shape are practically unlimited.

By far the most popular is the Hammerli free-pistol. It has swept the field in most International and Olympic matches. This popularity is based on the amazing reputation for accuracy that the gun has established for itself.

Basically the Hammerli is a cal. .22 long rifle single-shot Martini action pistol. The set trigger mechanism can be adjusted to maximum sensitivity. Since the slow-fire 50-meter International

matches are generally fired over a 3-hour period, a shooter must be able to relax his grip frequently. Hammerli free-pistol grips are designed for just that. When a shooter buys a Hammerli, the company requests a sketch of his hand and information on whether he shoots with his arm extended or bent in the European manner. The resulting grip will fit like a glove. However, if a shooter wants to shape his own, the grip can be supplied unfinished.

The Martini-type action of the Hammerli gives the rigidity and short hammer throw necessary in any super-accurate gun. The action also allows for easy loading and has a powerful extraction system.

The frames of earlier Hammerli free-pistols were machined from bar stock, a costly procedure. With the advent of precision investment casting, Hammerli chose this method to produce the frame and some of the internal parts. The

The trigger mechanism is the heart of the cal. .22 Hammerli free-pistol. It is carefully adjusted at the factory and can be adjusted to a very light pull. The exploded view of the trigger mechanism gives some idea of its complexity and why it should be disassembled and adjusted only by factory trained gunsmiths.

resultant gun is just as accurate as was the earlier model.

The Hammerli Models 101, 102, and 103 were replaced in February 1963 by the Models 104 and 105. The new pistols have the same mechanism as former models, but are fitted with improved grips, an adjustable rest for the trigger finger, and a larger trigger guard.

2 Two methods of rear sight attachment are used by Hammerli. Jhe later type shown here is attached by a sight retainer screw (37) and a retainer plate (38). When the screw is loosened, the rear sight slides off the integral sight mount. The earlier type uses 2 screws to retain the sight. These are under the leaf and tapped into the sight mount. The leaf must be raised upright to get at these screws.

3 Occasionally it is necessary to remove the breechblock (10) for cleaning. To remove it, lift the hinge pin retaining spring (15) slightly and push it forward and clear of the breechblock hinge pin (14). Push out the hinge pin. Depress front of the breechblock (10) and lift it out. It may be necessai7 to move the loading lever a bit to free it from the breechblock.

Hammerli International

IThe Hammerli has a miniature Martini action. To drop the breechblock (10), squeeze the lever latch (30) at rear underside of the grip. When the lever (24) is moved forward, it cocks the hammer (25), drops the breechblock, and actuates the extractor (20).

4 The cross pin (17) retains the rear of the trigger guard, the lever (24), and the hammer (25). Before attempting to remove it, loosen the mainspring retaining screw (28); this relieves tension on the cross pin (17). When cross pin is out, the trigger mechanism can be removed intact by removing front guard screw (23). ■

Deer hunting is an interesting thing that reminds you of those golden old ages of 19th centuries, where a handsome hunk well equipped with all hunting material rides on horse searching for his target animal either for the purpose of displaying his masculine powers or for enticing and wooing his lady love.
