NORINCO 7.65 mm Type 64 and Type 67 silenced pistols
The NORINCO Type 64 is a pistol produced solely in silenced form. It may be used either as a manually operated single-shot arm or as a self-loader.
When the maximum silencing effect is required, the selector bar is pushed to the left and the lugs of the rotating bolt in the slide engage in recesses in the receiver and the weapon fires from a locked breech. After the round has been fired the slide is hand-operated to unlock the bolt, retract the slide and extract the fired case. When the selector bar is pushed to the right, the locking lugs do not engage in the recesses in the receiver and the pistol functions as a blowback-operated semi-automatic. This results in a more noisy method of operation as the slide reciprocates and the empty case is ejected. The cartridge is 7.65 × 17 mm. It is rimless and unique to this pistol; no other round can be used.
The silencing effect is obtained by placing a large bulbous attachment on the front of the receiver extending well forward of the muzzle. The gases leave the muzzle and expand into a wire mesh cylinder surrounded by an expanded metal sleeve. The bullet passes through a series of rubber discs which trap the gases. Used as a single-shot manually
operated pistol it is extremely quiet but its reduced muzzle velocity greatly affects its powers of penetration.
The Type 67 is an improved model; in essentials it is the same as the Type 64 above but the silencer has been reshaped, making the weapon easier to carry in a holster. There are some small changes in the assembly of the silencer but the principle of operation remains the same. It is chambered for the 7.62 mm Type 67 cartridge, a rimless, necked round of reduced velocity.
