CHAPTER VI - REPAIRING AND OVERHAULING

WHEN A PISTOL DOES NOT FIRE

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.
