Pictures are floating about the web and gun forums or a Glock 46, a new design including a rotating barrel and the ability to disassemble the gun with out pulling the trigger.
Looks like it might have been made for a German police contract. Pictures and information appear to be coming from the German DWJ magazine.
Here is a link to a copy of the magazine. Unfortunately it looks like this upload being shared online may have been uploaded in violation of copyright rules, so I don’t know how long this link will work.
