racking down on cracks and
missing springs is important to the
health of your M9 pistols.
There are no
ifs
,
ands
or
buts
about
cracks. Eventually, your M9s will
crack. It’s your job to catch cracks
before they become dangerous.
After every firing, eyeball the slide
rails and the area around the magazine
catch for cracks. That’s where cracks
usually appear. Cracks in the receiver
or slide make the M9 NMC. Turn it in.
Support can replace the slide.
Also check the locking block for
cracks, particularly the left side. Sev-
eral armorers have reported locking
blocks whose left sides were broken
off. A damaged locking block damages
the receiver and slide. Support can re-
place the locking block.
It’s difficult to clean in the magazine well without dislodging the trigger bar
spring. ZING, it’s gone. No spring means no firing.
You can lose fewer springs by pro-
viding your unit soft brushes for clean-
ing around the spring. Soft brushes get
rid of most of the dirt, but are less
likely than a toothbrush to dislodge
the spring. If your self-help store
doesn’t have brushes, you can order
some with NSN 7920-00-514-2417.
When pistols come back from the
range, function test them before you store them. If a pistol fails to fire in double
action, the trigger bar spring’s probably gone. Replace the spring, NSN 5360-01-
204-4350.
Measure recoil springs. If the spring’s shorter than five inches, firing slows
way down. You can replace short recoil springs yourself with NSN 5360-01-
206-0934.
Check for cracks
around slide rails.
