I have done this with P90 to P90DC simply by swapping the manual safety slide for the correct decock only slide. From the information I see, I would think that the P95 would be the same.
Check out -www.gunpartscorp.com- for slide availability. Right now when I looked they had a listing for both blued and stainless decock-only slides. Be sure you are looking under P95DC (and not P95 or P95DAO) when you select a slide to order.
For those looking to convert a P90 to P90DC, gunpartscorp.com lists a P90DC slide (stainless) assembly, but they have been out of stock for months. If anyone is interested in a P90DC slide, I have one listed in the current classifieds here.
