I like G10 grips, but I ultimately settled on some wood grips that had a bit of swell to them, but not quite as much as the factory plastic/rubber grips. i found them on ebay but unfortunately the seller, KSD Grips, seems like they're no longer making grips.
I've got small hands, myself and replacing the stock grips with pretty much anything helped the reach a lot.
My next mod will be better sights, personally. Tested a set of competition rear sights with a fiber optic front that a gentleman was nice enough to let me use and I loved it. My 75B omega is strictly a range gun, so it's just for play.
