As with every type of machine and all firearms, Glock pistols do have
some parts and occasionally require maintenance, adjustment or
replacement. Wearable parts are those that by their very nature will not
maintain absolute factory specifications forever and will need to be
monitored periodically for satisfactory function. Generally it is
recommended that all Glock pistols be detailed disassembled and
inspected by a certified armorer at least annually.
