The P95 may need a new extractor as they have had issues with them not being hardened and become bent causing FTE'S. They may have corrected this but I have not heard publicly that they have.

P89 (have one) have an alloy frame and weigh a little more. As far as working the slide on it, no problem for me. just grab it at the rear where the Ambidextrous safety/de-cocker is. They have a good ejector on them.
Also I am seeing the P95's going for about $340 new here.
