I Reitterate: What I discribed with regards to cutting off the mag catch & Drilling it for a Pin punch TOOL. THEN the retaining CROSS PIN that holds the Ejector & magazine catch assembly in place could be welded with a 'Blob' of weld deposit on the NON Headed side. Thus 'Premanantly' retaining the Modified catch that NEEDS a tool to remove a magazine! HOWEVER, in the event of a broken componant, the weld could be ground off, the parts removed for replacment or repair & the pin re -welded again. THUS, the Magazine is NOT 'Readily Removeable' without a tool. But IS, removable, AS PER YOUR LISTING REQUIREMENTS, that you wrote about earlier. Failing all else, MOVE HOUSE, from 'The Peoples Republic of California'!.......
