My father in law...on my recommendation, purchased a Ruger LC-9 for convenient concealed carry. He loved it so much he bought two. One to carry and one for...well...he bought two.

He was 79 at the time and gave me something he used to modify his two Rugers that made them easier to operate.

He cut short 2" strips of this hyper sticky-backed abrasive tape...used for the likes of steps on a pool ladder.
He stuck them on to each side of the slide near the rear where Ruger had decided that some very shallow grooves cut into the aluminum were sufficient to grip and rack the slide to chamber a round.

I loved it. Works like a charm for effortless slide draw on that firearm.

Perhaps such a thing would alleviate your issues with grip on other items. Might be worth a try.

Looking at the 3M and Milwaukee Adhesive versions now, trying to balance the strongest adhesive for small strips vs not too thick on the item being taped. Thx!
