I've tried the Nill equivalents and really liked them. I have a set on a P210 now. They are a big target grip but very comfortable imo. I don't think the Roco grips will be finished quite as nicely as the nills but they should fit pretty much the same and will still be good quality.
I have bought various products from Roco direct in the past and they (correction - it was Doris I dealt with) were great to deal with and the shipping was way cheaper than Brownells.
