ok stuck trying to get the trigger pin out of a DM5 body have looked on the nation got the frame the right way up and smashing the crap out of it, and it aint budging
Needs to be at least on a hard surface and ideally in a vice. If you are not already also use a metal hammer rather than a rubber mallet as with both you get a much more forcefull 'shock' to the pin.
If you get really desperate then this stuff is the nuts!
