The M10 was built predominantly from steel stampings. A notched cocking handle protrudes from the top of the receiver, and by turning the handle 90° would lock the bolt, and act as an indicator the weapon is unable to fire. The MAC-10 has a telescoping bolt, which wraps around the rear face of the barrel. This allows a more compact weapon and balances the weight of the weapon over the pistol grip, where the magazine is located.
The MAC-10 fires from an open bolt, and the light weight of the bolt results in a rapid rate of fire. In addition, this design incorporates a built in feed ramp as part of the trigger guard (a new concept at the time) and to save on cost the magazine was recycled from the M3 Grease Gun. The barrel is threaded to accept a suppressor, which worked by reducing the discharge's sound, without attempting to reduce the velocity of the bullet. This worked well with the .45 ACP versions, as most loads are subsonic already, as opposed to special, low-powered subsonic loads usually required for suppressed 9mm weapons.
Due to the weapon's poor accuracy, in the 1970s International Association of Police Chiefs weapons researcher David Steele described the MAC series as "fit only for combat in a phone booth".
This is why it was better to use with a suppressor with a two stage design, such as the one from Sionics. Not only did it give the weapon a distinct look, and was very quiet only hearing the cycling of the bolt. The last benefit was an increase in better accuracy. See the Ingram MAC-10 footage here.

I shot the .45 caliber version quite a bit.It’s fairly accurate once you learn how to handle it.Poeple size targets at 50 yards are not a problem.
....People size targets at 50 yards are not a problem...
As with any firearm, practice is needed. These are fine at close quarters. Their rate of fire is very fast, so practice is needed there too.
What’s a phone booth?
I have one of those around here...left by a buddy in case I ever needed it.
I have never fired it.
Back when I lived in Miami you could buy one in any pawn shop for about 100-125 dollars.
Would make nice weapons to drop over en mass over the NK countryside for the peasants...with LOTS of ammo.
It’s just hard to believe that the two young actresses in that photo are now 51 and 57 years old respectively. I suddenly feel very, very old.
A video that shows just how quiet the Mac 10 can be with a suppressor: https://www.youtube.com/watch?v=YSiLmpaDknI
An empty enclosure with a chain that used to tether a phone book to it for convenience. A bar that my Dad played softball for had one back in the '50s.
I held one of those in the Mac-10 rifle configuration. First thing I noticed was it was well balanced and very comfortable. More comfortable than the Thompson next to it.
I did not get to fire it but it balanced very well.
My favorite line from that movie! I saw it in the 1980s and never forgot it.
Ever time a MAC10 or 11 post comes up that line comes to mind.

IT was really intended as a “dump and run” weapon.
You walked up to a confined space such as a car, dumo the magazine into the space, drop the weapon and run the hell out of there.
The idea was to kill everyone in the space, the weapon as a drop was cheap enough to produce so there was no loss to dropping it to free the perpetrator to depart, unfettered by having to tend to a spent weapon.
