Death Wish 2 Beretta ID

[Mauser]

Could anyone help me positively ID the Beretta used by Bronson in Death Wish 2. I had originally listed it as a model 85 due to the scene where Bronson was loading a single stack mag into the pistol. But people have brought up in the discussion page the fact that the gun has a rounded trigger guard and suggested it was an 87. I don’t believe the pistol is a .22, so I thought it could be an 84. The 84 uses a double stack mag unlike the single stack you see Bronson insert into the gun. I’m not sure if mags are interchangeable between model 84s and 85s or if there were 85s produced with rounded trigger guards. Any ideas?
