Walther patents anti-disassembly mechanism

Carl Walther GmbH has filed for a patent on a mechanism which prevents a pistol being disassembled if a round is chambered. It works by using the extractor to manipulate a pin which prevents the disassembly.

Diagram from the patent.

Personally, I think all gadgets like this are unnecessary. Police departments, on the other hand, love these kind of features. That the Glock requires its trigger to be pulled on disassembly has often been cited as a reason police have switched away from the Glock in favor of its competitors.

The patent application can be viewed online at Scribd.com.

    I remove the magazine, then rack the slide a couple of times, then make sure the chamber is empty, then ride the slide home until it's almost closed, then again check that there is no brass in the chamber (with the slide almost in battery). Then I aim and fire in a safe direction (half expecting it to go bang).

    Safety mechanisms should make sure that the firearm won't discharge on it's own when carried or handled or possibly struck or dropped. They should not replace the brain of the operator.
