I have used Craig Spegel's grips, slightly modified, for years. Smooth, minimum bulk, no finger grooves. My original set ( have newer ones as well) is now about 27 years old. They get a light refinish of Tru-Oil every couple of years and bid fair to outlast me. You could try him but I don't think he makes them any more (not enough demand).
The Ruger target grips shown are somewhat similar, and I could live with them. Unfortunately they are few and far between.
Finally, Hogue makes those Monogrips in pebbled nylon as well as rubber, and I much prefer those as they do not print or drag, while providing a good grip. Got my last couple sets from Brownell's.
