I don't have any problem at all with my Walker using a wooden crab hammer (that's also the same thing as a child's wooden peg hammer, but I digress).
I'm having a lot of problems with my Dance and Brothers wedge, though. That little catch does too good of a job holding the wedge in place, it's like I need to hold a screwdriver or a needlenose pliers against it so I can knock the wedge out. It's already marred the finish after only a few whacks. I've only taken the barrel off twice. I've only shot it once because it's such an annoyance to remove and therefore, to clean.
