I had TercGen make a set of grips for me using 3906 grips which have a curved backstrap unlike the normally used 3913 grips which have straight backstraps, and he did an excellent job.
Their shape went well when paired with the Kahr magazine base plates.
I knew going in that the Delrin grips have always tended to have a slippery feel for me, especially when my hands are cold & dry, as
GaryS also said for him, but I gave it a try anyway.
I too ended up putting grip sleeves on it but they loosen up after a while & feel mushy when they no longer fit snugly giving a less than secure feel.
The last item that caused me "grief" about them was the very angular heel of the grip lending to be more likely to print when carried AIWB. Admittedly the 3906 grip possibly accentuated this.
So I ended up selling them & going back to the Hogue grips but first I used my Dremel, with a small sanding drum on it, to re-shape them.
First I rounded the heel then I removed what I could to taper the vertical edges of the backstrip, also working the backstrap's hump to lessen it.
You are limited on how much of the softer rubber you can remove as the grips are layered so go slow.
I liked the improvement so much I plan on doing the same thing to my CS40's grips.

I don’t think anyone is currently doing the mod. I agree with you in that I personally ruined three grips trying to do it myself and I’m above average talent wise. That’s not a good thing cause there’s three less available of non renewable product.
