the original target grips S&W put on their revolvers in the 1950s and 60s were slimmer and had a palm swell that looks like a coke bottle shape from the rear. the target grips of the 70s and 80s were a good bit chunkier.
I'm a fan of the coke bottle grips.
Keith Brown and Karl Nill each sell some more high-end versions too
