Hi, Tony. The Gun Digest Book of Firearms Assembly/Disassembly covers this pistol, but it's fairly simple to explain. Starting with the pistol empty and the hammer in the fired position, take the magazine out. Then, use a fingernail or paper-clip to pull the top of the little "prong" in the middle of the backstrap back and down. Once that's pulled all the way down, you can pull the bottom of that piece straight back out of the backstrap, then pull the whole assembly down out of the pistol (this pulls a round pin down out of the back of the tubular receiver). This also frees the bolt to come straight back out of the receiver. Once that's out, you can use a rubber or leather mallet to tap the tubular receiver forward off of the locking step that holds it to the grip-frame. Re-assembly is in the reverse order, but you have to hold the pistol pointing up towards the ceiling to get the end of the hammer strut back into the mainspring housing, otherwise it either won't go together or won't cock. (The mainspring housing is the first piece you take out at the beginning). I hope this helps.
