looking at the pic, the pistol appears to have a mat or brush finish. It also appears that the finish may be black parkerized as you can visibly see where the front portion of the slide was heat treated (hardened) at the factory. If you can polish it, you could blue it also. Looking at the only pic of the slide, it was done on a wheel and the sharp edge was lost. The frame edges on the other hand look decently sharp. If you want to pursue this, I would completely disassemble the pistol, go to a lowes or home depot and buy a 1'x1' square polished marble or granite tile to use as a polishing table. Then get yourself some aluminum oxide (auto grade) sandpaper, it's black and is available at walmart start with coarse in the 100s(if there is no pitting, start with 240) working up 240, 360, 500 grit. If you want a Python grade shine, work on up to 1000 grit.
The process:
For the slide, place it in a vise between wood blocks making sure to not over tighten...all you want is snug. Polish the top using shoe shine method with the sand paper. For the sides of the slide, with the sand paper on the tile, place the slide FLAT and run it across the paper front to back going in one direction. This will return the missing sharp edge to the slide. Pay attention after every few strokes to make sure you are not obliterating the lettering/pony nor the serrations (although these can be sharpened using a small needle file if required).
Polish the frame using the same technique.
Bluing Recipe for doing small jobs such as a pistol:
DO NOT ATTEMPT TO PLACE THIS SOLUTION IN an ALUMINUM PAN or PLACE ANY ALUMINUM ITEMS IN THE SOLUTION AS IT WILL BE DESTROYED!
2 parts Sodium Hydroxide (lye) about 2lbs
1 part Ammonia Nitrate about 1lb
distilled water have 2 gallons on hand
XXX Steel wool
small spool of steel wire
glass candy thermometer that will register at least 300*F
2 metal pans that the pistol will easily fit into and are deep enough to completely submerge the pistol. 1 is for the solution, 1 is for water
Make sure you are out doors in well ventilated area when first mixing solution as it will give off very strong ammonia fumes.
Wear eye protection!
using a steel deep pan, place the lye in first then add the ammonia nitrate. Pour in a small amount of distilled water, just enough to moisten the mixture. There will be a chemical reaction with the mixture reaching boiling temps. Once this occurs and the fumes decrease and the solution is no longer volatile, slowly add more distilled water completely covering the salts. You want the mixture to be deep enough so that the pistol/parts can be completely submerged.
Heat the solution to 290* (Make sure solution is at 290* and no more than 300* or the part will come out red/purple rather than blue/black)
using piece of wire tied to the part, submerge the part into the solution so that it is completely covered but suspended so that it doesn't rest on the bottom of the pan to avoid heat spots. Leave the part in for 20 minutes, remove and place immediately into water pan allowing to cool. Clean part gently using XXX steel wool and dishwashing detergent (dawn works best) examine part to make sure it's satisfactory, if not rinse the part with water and repeat the process. Spray each completed part down with WD-40. Once the job is complete, fill water pan with fresh water and add a box of baking soda and boil parts in it to avoid any bluing creep. Rinse with clean water. Following this, dry all parts and oil with a quality gun oil such as BreakFree. Re-assemble weapon.
