To get a more secure grip many of my concealed carry 3rd Gen Smith's sport stippled grips.

I do all the checkered area....... sides and backstrap. A fish scale pattern with a soldering iron.......

Warning..... just go slow; don't overheat the grips or you can warp the front/top/bottom edges of the grip........ if you do; boiling water will allow you to adjust them ( submerge ( about 30 seconds) the section of the grips that's warped then squeeze the sides together/hold till cool) back into shape.

I generally over compensate and have to "force" the grips over the frame, for a really good, tight fit.
