ABSTRACT:
A two-part chamber block for a handgun which does not interfere with the inspection, operation or field stripping of the weapon other than access to the chamber and barrel. In a first embodiment, two lengthwise segments can be offset, inserted into the barrel and then aligned and retained by a cable tie or similar to prevent their removal. In a second embodiment a cable tie, or similar, connects a chamber portion and a barrel end portion to effectively block the chamber and barrel. A third embodiment uses segments inserted from opposite ends of the barrel with opposing teeth which interlock to retained the segments. Optional locking collars, latches, and configurations increase the adaptability of the chamber block.
