Mendoza HM-3
Notes:
This weapon was developed in the early 1970s, and was to become the
standard submachinegun of the Mexican forces in 1976.
The unusual feature of the weapon is the bolt; it is very large, and is
not telescoping in the usual sense, but instead telescopes around the barrel.
In addition, much of the bolt (and bolt spring) is exposed, to allow the
weapon to be partially cleaned without disassembling it.
In a sense, the operation of the HM-3 is much like a giant pistol.
The folding stock is also unusual; the stock is meant to be opened with a
simple flick of the wrist. As I
said, the HM-3 was meant to be the standard Mexican submachinegun.
Instead, there were too many unusual features, especially the large
exposed length of the bolt and recoil spring, and only a small number were
bought by Mexican military and police forces.
The Mexicans decided instead to use the German MP-5.
Some 30 years
later, the US company of X-Arms brought out a new version of the Mendoza, called
the Cobra. Differences are
primarily in the caliber and barrel length (8.2 and 10 inches). Another version
is the Bulldog, with a 6.2-inch barrel. The receiver and grip of the Cobra is
primarily of polymer, as is the buttplate of the right-folding stock.
The rear sight is adjustable for windage and elevation, while the front
sight has a fiberoptic inlay. The
barrel is threaded for a silencer.
Proprietary mounts allow for special sights or optics.

Notes: Production of the HM-3 was restored in 1997, and large numbers of them
were used during the invasion of the US.
Merc 2000 Notes:
The CIA liked this weapon, as it confused enemies when it was captured; Mexico
didn’t otherwise have a high profile in the espionage world.
