Item #: SCP-4XXX
Object Class: Safe
Special Containment Procedures: SCP-4XXX is to be locked in a Weapons Locker at Site-19. Access to SCP-4XXX can granted to Research Personnel with clearance level of 3 and higher.
Description: SCP-4XXX was previously used by Agent ████████. The object appears to be an ordinary Glock 21 magazine. The ammo capacity of SCP-4XXX appears to be unlimited. The SCP-4XXX will accept standard .45 ACP bullets. If a smaller bullet is inserted into the object, The
SCP-4XXX will turn it into the .45 ACP bullet.
When SCP-4XXX is inserted into the Glock 21 and the pistol is fired it will continue shooting until all rounds loaded into SCP-4XXX have been shot even if the object was detached from the pistol. When there are no more rounds in SCP-4XXX, it will detach itself from the gun if it wasn't detached previously. It is not possible to insert the SCP-4XXX back into the weapon it was previously attached to. Object will not lock in place and will fall out of the gun. If the SCP-4XXX is unable to fall out, it will refuse to load the bullet into the chamber. Any attempts to disassemble the object have failed.
