I don't have a bodyguard, but I have a Kahr that is a little fussy about taking the slide off, you have to be pushing forward on the slide with a moderate amount of force then pull the trigger. Push too hard, no go, push too soft, no go, pull the trigger then push no go, gotta be just right. It's like Goldilocks when it comes to field stripping.....not sure if this technique can apply to yours but sounds like it wouldnt hurt to try??
