NOMENCLATURE

Smith & Wesson firearms are reliable and safe to use when the

firearm safety rules are followed. There are a number of internal

safety mechanisms within the lockwork of the firearm which

ensure that the firearm will not discharge unless the trigger of the

firearm is pulled. That is one reason why it is important to never

modify or alter your firearm. Before you use your firearm, you

should be fully familiar with its operation.

Here is a list of basic firearms terminology.

AMMUNITION - CENTERFIRE - Ammunition which contains the

primer in the center of the base of the case. Among the most

common centerfire firearm cartridges are the .32, .38 Special,

.380, 9mm, .357 Magnum®, .40 S&W®, .45 ACP, .44 Magnum

and 5.56mm.

AMMUNITION - RIMFIRE - Ammunition which contains the

primer material in the rim. Among the most common rimfire

firearm cartridges are the .22 Short, .22 Long, .22 LR, and

.22 Magnum.
