Okay, still no luck getting this thing apart (I know, it's been a while) and, unfortunately, I've given it a few small scars in the process.
So, my next question is: could I disassemble the gun and throw the cylinder in the oven at around 450* to heat it up? Will this damage the bluing? Will 450 degrees be sufficient to loosen any loctite? I'm somewhat confident this will work, but this is my first blued gun and I'm still not quite sure what it will hold up to.
By the way, thank you for all the suggestions thus far.
