I went to take the factory rear off my P-01 and it wouldn't move. Placed the slide in a padded vice and progressed from a small hammer (with Dawson aluminum nylon tipped punch), to a carpenters hammer and then to a large ball peen hammer and it still wouldn't budge with some big wacks. (Of course I removed the set screw.)
I took extra precaution with 18 quintillion layers of masking tape and managed to still mar the sight a little, but the slide is still untouched. Do you think an overnight soak of Zep, PB or Liquid Wrench will make a difference in this case and will it hurt the polycoat?
Does anyone know of a decent low-priced sight pusher because I only plan on using it once for my P-01. I did the sights on my PCR a couple years ago and the rear sight came out right away with a couple of light wacks, but this one IS IN THERE! Thx.
EDIT: I tried hitting it out from right to left because I can see it was installed at the factory from left to right. I even tried tapping it out the other way. No dice.
