Emerging smokepowder weapons in my fantasy

As their metallurgy improved, they even put it in small "hand cannons," working their way down to regular muskets and pistols.

But this is a fantasy realm, with gods of crafts and artifice. They could possibly have the high-grade metallurgy needed to not have man-portable guns blowing up in people's faces all the time.

But I'm not sure of anything I just said, so take with a grain of salt. :-)

I know why it happened in the real world.

I was just making the point that in a fantasy world where metallurgy was already at a similar level to our 17th century, it is unlikely that there is any great mystery involved with making strong gunbarrels.
