     3. When a pistol does not fire 
    within the allowed pressure limits on the initial test at the 100 foot 
    setting, the firing operation should be repeated several times. If the 
    firing pres-sure is consistent and does not exceed the allowed pressure 
    limits by more than 5 psi it may be assumed that the defect is of a minor 
    nature and can be corrected by recalibrat-ion of the pistol. However, should 
    erratic pressure readings be recorded on repeated fir-ing of the pistol or 
    should the firing pressures exceed the allowed pressure limits by more than 
    5 psi the pistol should be broken down for examination as to the cause of 
    malfunc-tioning.  |
