After firing of 1000 rounds in each M9 Pistol, thefiring pin protrusion shall be measured and compared with the measurementobtained at the start of the test. If the differ

The occurrence of a misfire resulting fromexcessive fou

If the protrusion is lessthan .025 inches, it shall be assumed the misfire was fouling induced andlot shall be rejected. The occurren
28、ce of 2 or more misfires during thefouling test shall also result in rejection of the lot.4.5.11.6 Other firing defects .
