Threads exactly the same. If it doesn't come undone via hand pressure (ie: if you need to apply heavy clamping and leverage to move it), I would leave well enough alone and go forth with it and have fun. One of my 1899H's barrel is so tight in the receiver that I shrugged my shoulders and just treat it as a solid frame.
