J-frame help please

I purchased my new 642 last summer and looking to change out the factory grip with a set of Pachmayr's. Can someone tell me what size screw (I think it is a torx head) is holding the grip as I do not have a set of these type screw drivers and will need to buy one.

Thanks in advance

In one of the other/earlier threads, the torx size is listed as T-10.

Thanks, I actually was able to get a small Allen key to work.
