Had a P95 in the late 90s and unlike Glock/XD/M&P and other polymer pistols, Ruger P95's frame was made from hard zytel-like material. The slide rides on the zytel rails (yes, no metal inserts) and over the years, wear issue has not been a problem in maintaining the accuracy. All other parts are stainless steel. The width of P95 is wider than most other polymer pistols.
Unlike Glock/XD/M&P which are striker fired, P95 is hammer fired. It is a fairly smooth pistol with shorter barrel (design accuracy was good enough that Ruger kept trimming the barrel length from 4.5" to the production length of 3.9").
It has ambidextrous controls (safety/Decocker, mag release) - I really liked the mag release (you push forward on the release), but did not like the trigger (to me, Ruger triggers are long). It was accurate shooting and if it had a better trigger, I would have kept it.
FYI, on our recent range shoot, a P89 out shot all semi-autos in 9mm accuracy.
For the similar price range, have you considered looking at a S&W Sigma?
