With any saw you'll have the problem of the edge chipping out.

When I put on a recoil pad, I flatten the butt with a sanding disk in the radial arm saw and the edges are sharp enough to cut your finger. The speed of the radial arm removes wood super fast with 100 or 150 grit sand paper, and there's no need to go to finer grit paper. If you need to shorten 1", saw short & sand to the exact length.

The stock is held in a jig (or sled) that fixes the angle and slides right & left to get the depth of cut. There's a wooden V block fixed at the top 90 degrees to the cut to locate the comb of the stock. A second adjustable wooden V block locates the belly of the stock, so the two V blocks center the stock square to the cut, side to side and square to the comb. Bad description, I hope you can make it out!
