Care and Cleaning
PistOls should be field stripped and cleaned at
reasonably frequent intervals to insure proper
functioning.
Use any good commercial solvent, and after
cleaning, lubricate sparingly with a light weight
gun oil. Outside surfaces may be protected from
corrosion by coating lightly with a rust inhibiting
oil or grease.
Be careful not to d~op magazines, as they may
be sufficiently deformed to cause failure to feed
properly.
