Don't know what Cratex wheel is but that might 'polish' it and put a glare on the sights...
(added picture to OP)
A Cratex (brand name I think) will polish glass or metal. It comes in different grits but if anything CAN be polished, a Cratex wheel will do it!
I'm very happy so far with my LC9sPro and just thought I'd toss out the sharp top edge of rear sight post to see if mine was different from others. I'll be back at the LGS I bought it from and if I remember will compare it to other same model.
If you own a Dremel type hand drill you would like a Cratex wheel. It's hard to soft rubber with the grit imbedded and very useful for many things. In the smaller grit wheels you can polish without fear of hacking away too much material [object being polished).
