+1You just need to spend more time on it.
I cant tell from those pictures what you've done so far.
You'll probably need to start over again with a lower grit sandpaper, and work your way up to 2000 or so. THEN you can polish with the dremel.
Oh please, get a polishing kit from Sears, a 8-9" cloth wheel and the right polish and it is a breeze. Stainless polish or some ebony and it will look great. Just keep it moving as not to burn it.
What effect are you looking for on the slide? Shiny or just a different color?
Thanks everyone for the great responses and advice...
I think I will just leave well enough alone at this point and have it refinished when I can afford it...
I was going for a shiny look, against the black, kinda like this Sig Equinox:
Ooooh... A great opportunity to show off my 226 Equinox...
Trying to make ure bersa look like a sig....
Been there and done that. Did mine with a dremel as well. Turned out too good almost as I could barely see the sights in bright sunlight. Luckily the buyer I sold it to loved it. Next time around I bought the bi-tone.
In your shoes I would use a piece of 1500 grit wet sand paper on a flat surface. Keep it wet and use a little soap and make sure you're holding the slide flat against the paper. Once you take a couple of passes with the sand paper you can decide to either go up to 2000 or down to 1000 depending on how rough the surface is. What is most important is that you keep the slide flat against the paper. You don't want to round any edges. I would work my way up through the grades of sandpaper and finish with 2000 then some polishing compound on a rag. Its impossible to get a nice even finish with a dremel polishing wheel.
