A
ll MK19 machine guns should have had MWO 9-1010-230-50-1 applied to
them by now. The MWO changed the MK19's cocking lever from a one-piece to
two-piece design that will improve the gun's safety and reliability and eliminate
out-of-battery firing.
But some MK19s were missed—and
that's why TACOM needs your help,
armorers. Check your MK19s now to
see if they've gotten the MWO. If
they've been modified, they have a
dovetail bracket mounted on the right
side of the receiver and an "-M"
stamped on the left side immediately
following the weapon's part number.
Also check the arms room for a feed slide
adjustment tool that arrived in a square white
box with a label that reads "NSN 1005-01-467-
9435," the tool's NSN. The tool should have
come with the MWO. You'll need the tool after
the weapon has been modified. Instructions for
using the tool come with it. Also see WP 0073
00-1 in TM 9-1010-230-23&P.
If your MK19s haven't been modified or you're missing the tool, TACOM wants
to know about it. Contact Jeannette Morphew at DSN 793-0609/(309) 782-0609
or email:

M9 Pistol
Most of this also applies to the M9
pistol magazines. Load M9 magazines
by hand. Don't stretch their springs.
Don't leave M9 magazines loaded all
the time. Keep them clean. Don't lube
them in the desert. Disassemble and
clean them after every mission. Keep
magazines in their sealed plastic bags
or the ammo pouch, NSN 8465-01-
207-5573, as much as possible. See
Page 3-26 in TM 9-1005-317-10 for
care of the magazine.
But in the desert don't lube
any part of the magazine.
Lube will just attract sand,
which leads to jamming.
In the desert especially, do
everything you can to keep
sand and dirt out of maga-
zines. Keep magazines in their
sealed bags. NSN 1005-00-
193-8306 brings 500 plastic
magazine bags.

When possible, don't leave magazines fully loaded all the time.
Over time that
pressure may cause the magazine's spring to lose its spring and then you may have
feeding problems.
Of course, a dirty magazine will be more likely to jam, especially if sand is coat-
ing moving parts. When you clean your rifle, also clean magazines. Take each mag-
azine apart and run a clean cloth through each tube until all dirt is gone. Wipe off
dirt from the follower and spring. If you're not in the desert, lightly lube the spring
to prevent corrosion.
