Smith and Wesson Model 76 9mm Submachine Gun
The Swedes cutoff export of their M45-series submachine gun (SMG) to the Americans as a result of our involvement in the Viet Nam War. Special operations operators were forced to cast around for a replacement. What they found was a U.S.-built, re-engineered version of the Carl Gustaf M45D called the Smith and Wesson Model 76. Smith and Wesson marketed the SMG to both the U.S. military and civilian law enforcement agencies. Limited numbers were used by Navy SEAL Teams and by other special operations forces. However, the gun did not sell well and was eventually dropped from the S&W line by the mid-1970s. S&W did not copyright the M76 and another series of private manufacturers marketed the gun in both 9mm NATO and .45 ACP as the MK760.
If a close comparison is made by of the Carl Gustaf M45D and S&W M76, the similarities are striking. The cocking handle is on the right for both; both have rear sights protected by "ears" that are welded to the receiver; both have their front sights welded to a perforated barrel jacket; and both have a folding stock that is very similar to the other except that the stocks fold in opposite directions. Like its predecessor, the S&W M76 uses the same box magazines as the M45. The form and shape of this 9mm magazine is peculiar to the M45, M76, Egyptian "Port Said", and no others. The M76 or later MK 760 can be found fitted with the very effective SG9 suppressor ("silencer") manufactured by AWC (Automatic Weapons Company).
