No, they are completely different grip frames. As far as the stippled 952 grips, you MIGHT find someone who would be willing to trade. IMO, given the collector value on these, most owners would want to keep them in factory as-built configuration.
The stippled grips are hard to find, you may have to keep looking for a year or more. I got some from a lady here in TX who had three sets to sell. How she got them I have no idea, this must have been 7 or 8 years ago. I have a NIB 952-2 that I will eventually sell and will include them with that package.
There are almost no grip/stock options for the 952.
I am certain that 52/39 stocks and grips will not fit, even though it would seem like they might. The screw locations are close but NOT the same. I would love to hear an insider’s answer as to why because this is as ludicrous as it sounds.
There is one company I know of that has made aftermarket stocks for the 952 and that is KSD in Turkey. I have not looked at their site in some time so I can’t say for sure if they still do. They are nice stocks.
Nill made a stippled set, and I regret not buying them when I had the chance along with the same for my 845. It’s good to know they exist though, right?
