Hungarian Model 37 Field Stripping   To strip the M37, first step is to be sure gun is unloaded. Pull slide (2) to rear until slide stop (38) engages rear notch as shown. Rotate barrel (8) and pull it out of slide. Then release slide stop, ease slide off frame, and remove magazine. A single pin (3) retains firing pin in slide and acts as extractor hinge pin. Hold slide in padded vise as shown and drive pin out., Remove firing pin (7), finning pin spring (6), extractor (4) and extractor spring (5). Only difficult piece to reassemble is hammer spring (16). A slave pin is employed to retain the hammer spring (16)  and plunger (15). This slave pin is a short wire or nail that holds assemblies in place until proper pin is inserted. Correct pun (24) is driven through frame and knocks out slave pin. Disconnector (12) and ejector (11) are retained by cross pin (27) through frame. Remove pin and disconnector will drop out; however, ejector must be driven out as shown. When reinstalling cross pin, be sure it is in slightly below the surface to prevent retarding slide motion.
