Puella Magi Madoka Magica the Movie: Rebellion
The following weapons were used in the anime film Puella Magi Madoka Magica the Movie: Rebellion:
The first gun that appears onscreen is a Glock 19 wielded by Homura Akemi.
Heckler & Koch P7M13
Homura uses an H&K P7M13 in close quarter combat after losing the MG 42 and throws it away upon landing after free-falling.
Beretta Px4 Storm
Homura uses the Beretta Px4 Storm while freefaling again and upon landing.
Homura throws away a P5 and pulls out another P5 with a different finish.
Homura whips out a Beretta 92FS in her encounter with Sayaka.
Desert Eagle XIX
Homura uses a Desert Eagle XIX later in the movie and also in a flashback.
Mami Tomoe wields a magically summoned percussion pistol that only appears onscreen for about a second while she was in free-fall.
It's surprisingly modern in design compared to her muskets, with a vertical "pistol grip," and screwed in grip scales; quite different from real life counterparts.
Double-barrel percussion shotgun
A pair of magically summoned shotguns used by Mami, in a "sawed-off length." Appears to be based off of her muskets, which were also explicitly mentioned to be capable of firing shotgun shells.
Homura pulls out an MP40 with a silver & wood finish, this finish disappears in a later shot.
Sa. Vz.61 Skorpion
Homura uses a Skorpion Vz.61 after discarding the MP40.
Heckler & Koch MP7A1
Towards the end of the gunfight, Homura uses an H&K MP7 with a Zeiss RSA-S relfex sight.
DSA SA58 Pistol
Homura switches to a modified DSA SA58 Pistol quickly after the MP7.
Percussion-lock rifled musket
Mami's primary weapons are percussion rifles summoned and powered by magic. As in the original series, Mami is able to fire multiple in succession and simultaneously by hand or remotely by magic, as well as summon numerous types of small arms.
Homura takes out an MG 42 with a double drum magazine to lay down heavy fire. This is a cameo appearance of the fictional MG 42 variant from the World Witches series, modified to use (stylized) Patronentrommel 34 drum magazines and with the bipod removed.
