Silent Hill: Homecoming All Bosses NG+ Tutorial
So because I'm a dummy I totally forgot to grab the laser pistol dupe. Make sure to check out deadrobots guide explaining how it works.
All in all though you just grab the pistol when you come back to the Shepherd house after getting the Ceremonial Dagger. Then when you enter the underground after the church you kill all the order members with the pistol. Much easier than grabbing the regular pistol lol.
