It was all done by hand... no mechanical devices... a couple of thousand "man hours"...Lol those rugers with the black finish removed and polished shine up like chrome . Buddy of mine saw it at work and thought i did have it chromed . I am kinda glad the gunsmith mucked up the finish on mine so that i did what i did . That is one shiny p95 to . Did u use a buffing wheel of any sort or do it by hand like myself ? I might take the slide of mine and use the jewler's rouge and the buffing wheel to really make it shine .
