On the "other" forum, I posted a method I used then to make the LCP slide easier to grip. It consisted of using little strips of 3M stair tread tape stuck into the grooves on the right side of the slide (I am right handed and usually carry on my right side). Here are the photos I posted back then:
Here is the tape applied to the LCP's slide:
This is the tape that I used. It's available at Home Depot.
After carrying a bit and cycling the slide even more, the tape strips started to come off one at a time. I got several months' use out of one application but decided that wasn't good enough. So, I poked around the shop and found a container of coarse silicon carbide grit that I'd hoarded away. It's about 60 to 80 grit size. Here is a photo of the grit applied to the LCP and another of the carbide grit in a dish with a .223 55gr bullet for size reference:
I applied the grit to the LCP using these steps:
Obviously, this could be applied to any hard-to-grasp pistol slide and not just to the LCP's slide.
Though I got the small supply of silicone carbide grit which I have from one of my industrial customers while I was still working, I found a place where it can be purchased by anybody. The place is: The Rock Shed. I would suggest trying the 80 grit size first, though it's cheap enough to get a pound each of the two coarsest grits they sell.

I applied the grit to the LCP using these steps:
- Remove the slide from the LCP.
- Thoroughly clean the slide with MEK or Acetone.
- Plug the hole in the furthest forward groove (right side) with a round toothpick.
- Cover the extractor completely with masking tape.
- Using a sharpened toothpick, put a layer of epoxy glue in all of the grooves.
- Very carefully wipe off any excess epoxy that may outside the grooves.
- Carefully pour carbide grit over the epoxy using just a little more than needed.
- With a finger or a slightly rounded stick, poke the carbide grit to seat it better in the epoxy.
- Remove the excess carbide grit. Care in this step greatly affects the appearance of the finished job.
- Wait for the epoxy to cure before handling the slide.
- Thoroughly clean off any carbide grit that got into places where it shouldn't be (and it did).
Obviously, this could be applied to any hard-to-grasp pistol slide and not just to the LCP's slide.
