Dawn of the Dead (1978)

The weapons used in this movie are:

Adler-Jager AP-74

Peter (Ken Foree) aims his Adler-Jager AP-74 (standing in for a real SP1 or M16). The AP-74 was a .22lr M16 clone that had characteristics of both the SP1 and M16A1. - 22LR

The original M16, the first version, firing in a 20-round magazine, adopted in large numbers by the U.S. Army in Vietnam. This has the original 3-prong flash hider. It would later be replaced by the upgraded M16A1 - 5.56mm

• Used by all SWAT members, in particular, the characters of Peter (Ken Foree) and Roger (Scott H. Reiniger) but eventually discarded after raiding the gun store. In one shot, when Peter is unloading his weapon after shooting the zombie kids, we can see the tiny .22lr magazine. The Adler-Jager AP-74 is an inexpensive .22 AR15 clone (that was actually pretty close to an SP1 and much better looking than the .22 M16 clone made by Armscor). The guns were pretty much 'mime' fired, with only the sound effect and blood squibs to indicate that the rifle was fired.

The Armorers for the movie was an East Coast outfit called "The Plastics Factory", however other information on them are unavailable.

Ruger Single Six

A Colt Peacemaker single action type revolver is used by one of the survivors.

Roger appears to be loading this gun with .22 rounds, so that would mmean it is most likely a Single Six.

Colt Single Action Army w/ 4.75" barrel, referred to as "Quick-Draw" or "Civilian" model.

Derringer pistol

Peter(Ken Foree) when cornered in a room by zombies puts a Derringer pistol to his head contemplating suicide, but then realising that he can escape quits the idea.

Savage 99 rifle

Peter (Ken Foree) takes a scoped Savage 99 lever action rifle, possibly in 300 Savage, from the gun store for his personal use. He later uses it against the bikers when they invade the mall.The Savage 99 was chambered ,at various times, for .300 Savage, .308 Winchester, .243 Winchester,.358 Winchester, 250-3000 Savage, .22 High Power and .303 Savage (there were other calibers but these were the most common) during the 100 odd years that it was manufactured. The one in the movie was chambered in .300 magnum. When they are stocking up on ammunition you can briefly see peter grabbing .300 mags.

Possibly a contunity error. 300 magnum rifle rounds (Winchester and/or Weatherby) would not fit in the rifle and the Savage 99 isn't strong enough for that load.

It might have been .300 savage ammo. all i saw on the box was .300

Smith & Wesson Model 36

While waiting for Roger to return as a zombie Peter appears to be holding a nickle plated S&W Model 36. There is a possibility that it is the stainless steel Model 60 as well.

Colt Python

During the famous gunstore sequence there is a brief glimpse of a Colt Python in the display case. It is priced at $340.00. A substantial sum in 1978 when the movie was produced.For some unknown reason they don't take it.

Colt Python with 6" Barrel - .357 Magnum

Thompson M1928A1

One of the bikers who invade the mall is using a Thompson submachine gun with the fifty round drum magazine and the forward pistol grip.Possibly that biker is played by Tom Savini, special effect wizard on the movie.

M1928 "Tommy Gun" .45 ACP with 50-round drum magazine, made famous through countless classic gangster movies
