I believe this is another one of the model year differences between the P10s. I don't ever recall seeing a later model P10 with grey door handles. Does anyone have a late model p10 w/ the grey handles?
factory gray handles don't exist, unless someone had them painted that way. 91 to I believe 93.5 had black handles, and the 94 and newer p10's came with chrome. Either of these handles can be painted to match your paint color.
I changed my black ones over to chrome ones on my 93.5.. so now I have a set of black ones laying around... lol.. perhaps I'll go back to them some day if the chrome ones start to look like crap.. but for now.. I love the improved look!
