Meaning... your slide lock busted itself up? Part 92B-61?
If so, perhaps an aftermarket slide lock might work? I dunno, like a Guarder one is cheap - but on second thought - its made by Guarder... but then again, its only $19 USD from eHobby or whatever. There are also a few others out there that I saw (not on eHobby), can't remember who made them or where I saw them cataloged.
