Idle,
you should be able to get that out without taking off the stock.
Have you pushed out the takedown pin and tried to take it out yet? The takedown pin is the big one just above the trigger. Just push it thru with a small screwdriver, and then pull down and slightly back on the trigger guard. Again, as soon as I have a couple of free minutes, I'll post the Win1300 takedown process with pics, but you should be able to get past that once you take the takedown pin out. Getting it back together is acutally more difficult, but I'll take pics of that too.
DO NOT dissassemble the bolt completely unless you are prepared to look for springs and stuff all over your room. It's pretty well self contained unless you start pushing out pins and stuff. If anyone is interested, I can go into that process of pulling the bold apart, but it's under alot of tension so make sure to wear safety glasses as always.

PS... you do not want the hammer to be disengaged, it makes it a little more difficult to get out... so rack the slide, and put the safety on, leave it in the charged position when removing the trigger assembly.
