• In some cases, a round of ammunition not specified on your
handgun may fit into the chamber or cylinder. Firing
ammunition not specified on your handgun may cause it to
rupture and cause serious injury or death to you or others.
• Always inspect your ammunition before using it. Never use
dirty, corroded or damaged ammunition which can lead to a
burst cartridge which may cause damage to the handgun
and personal injury.

AMMUNITION WARNINGS
• “Plus-P” (+P) ammunition generates pressures in excess of
the pressures associated with standard ammunition. Such
pressures may affect the wear characteristics or exceed the
margin of safety built into some revolvers and could
therefore be DANGEROUS. This ammunition should not be
used in Smith & Wesson medium (K frame) revolvers
manufactured prior to 1958. Such pre-1958 medium
(K-frame) revolvers can be identified by the absence of a
model number stamped inside the yoke cut of the frame.
(i.e., the area of the frame exposed when the cylinder is in
the open position.
• “Plus-P-Plus (+P+) ammunition is not recommended for use
in Smith & Wesson firearms. The marking on the ammuni-
tion merely designates that it exceeds established industry
standards, but the designation does not represent defined
pressure limits and therefore such ammunition may vary
significantly as to the pressures generated.
• “Plus-P-Plus (+P+) ammunition is not recommended for use
in Smith & Wesson firearms.
• In the Model 940 revolver, some brands of 9mm parabellum
ammunition may cause difficulty in extracting spent
cartridge cases from the cylinder. If this situation occurs,
thoroughly clean the cylinder charge holes with solvent. If
this condition persists, we recommend changing to another
brand of 9mm parabellum ammunition.
• Smith & Wesson has found wide variations in primer
sensitivity between some brands and types of .22LR
ammunition. Smith & Wesson recommends that before you
put your .22LR handgun into regular use, that you fire
several boxes of your brand of ammunition through it to
determine reliability of ignition. If “failure to fire” occurs, try
different types of brands of .22LR ammunition until a
reliable loading is found.
