Well, I mean, maybe I'm a bit overconfident here. I think I would be able to crack open the gun just to drop in a hammer, provided it fits... BUT maybe that is a common novice mistake—to underestimate how complicated the internals and/or break something by accident in the process.
I've been looking for tutorials and guides on how to disassemble these things, but nothing really helpful has come up (maybe I'm looking in the wrong places?).
I mean, how hard could it be? I envision it like this:
- Crack open the sucker
- Take note of where everything is
- Zero in on hammer
- Replace hammer
- Put things back the way they were
Of course, this could all go to hell if something like a spring or something randomly pops out and I have no idea where it comes from. XD
