Government representative. The first round of each magazine shall
be fired unlocked. The hammer/striker shall be lowered before the
first round by use of the decocking mechanism. The barrel shall
be cooled after each 250 rounds. Twenty (20) magazines shall be
utilized during the test of each pistol. Each magazine shall be
coded and maintained with its assigned pistol.
4.6.7.2 Cleaning inspection and lubrication. The pistol
shall be cleaned and lubricated with lubricant per MIL-L-63460
after each series of approximately 500 rounds. No parts shall be
altered and only parts broken or worn to the extent that they are
unserviceable shall be replaced. At the close of each day's
firing the pistol shall be protected against corrosion.
4.6.7.3 Recording of data. A complete record shall be kept
for each reliability test, showing each stoppage and part
replacement including a complete description of the failure mode,
the round count at each occurrence, and the pistol identification.
Each stoppage and unserviceable part shall be scored in accordance
with Table I.
4.6.8 Durability. After completion of reliability testing
(4.6.7) the receivers from the reliability test pistols shall be
visually examined to determine compliance with the requirement of
3.4.0.
4.6.9 Safety. After completion of the reliability and
durability test, slides, barrels, receivers, and other parts
identified by the Government as critical shall be magnetic
particle inspected (MPI) or dye penetrant inspected (DPI), as
appropriate. DPI testing shall be in accordance with MIL-STD-6866,
type I, method B,sensitivity level 3,form D. Five pistols,
determined by the Government to exhibit most extensive crack
indications, shall be reassembled and fired an additional 5000
rounds. Each critical part shall be reinspected with the same
Inspection procedure as above. Three of these five pistols shall
be selected by a Government representative, reassembled, and fired
as follows:
Each pistol is to be fired to a total of 4000 rounds, or
until each original critical part (as determined above) has been
replaced because it has failed in a manner which precludes firing
of the pistol or causes unacceptably repetitive stoppages (as
determined by a Government representative). Each critical part
(as determined above) shall be subjected to visual inspection
after each 2500 rounds of firing. All parts except the barrel,
slide, receiver and other critical parts previously identified may
be replaced as necessary to assure continued firing. A critical
part may be replaced only after it has failed in a manner which
precludes firing of the pistol or causes unacceptably repetitive
stoppages (as determined by a Government representative). The
first article is rejected if any pistol component fails in a mode
which has the potential of causing injury to the operator or a
bystander.
