S&W used to ship N-frames with somethin' like these, in the late '80's ...
... those were the fattest grips I'd ever handled! ... but, it's a different feel from the round-to-square conversion grips!
I've since been competing mostly with a 1911 ... at which, I'm now favoring much more slender grips ... which is kinda odd, 'cause I've got XXL hands!
I now actually favor the factory/hogue rubber grips ... as they're among the most slender! ... and the extra traction is nice!
If ya want a fatter grip, but with some traction, I'd look at slippin' a hand-all 'er some such over a wood grip ... that JM might be a nice one, fer that?! ... not sure if anyone makes any such thing that'd fit well, though?! ... maybe borrow one, to check it out?!
Maybe seek out some 1-on-1 training ... work on yer grip ... if ya don't like Miculek's style ... and ya don't like Strad 'er my style ... maybe it's you?!
