... smoothing up the trigger is an easy operation with some fine crocus cloth. The action is fairly simple. Cleaning up manufacturing burrs and such doesn't take a college degree on this one...
Very true, but if you've not done it before, remember to go very slowly and be careful not to alter the engagement angles of the sear and hammer notch. (If you muck up the sear you'll have to get a gunsmith to order a new one as they are FFL restricted; Brownell's will happily sell you a new hammer, though- go figure. I speak from experience on this, having just worked on my Model 1895 that a previous owner had apparently tackled a little too aggressively.)
What I have found works well (aside from using a proper ceramic stone) is to get a piece of very thin but rigid steel strip and glue a piece of, say, 600 grit wet 'n dry to one side and 2000 grit on the other. (A thicker piece of steel with a bevelled edge, so you can get right into the hammer notch, such as an old planer blade, would work well, too.) Go slowly and work in good light and you'll be just fine.
