The P95 has been the subject of much discussion on this forum. The consensus being, it's rugged, reliable, inexpensive, big, blocky, poor sights, and has a terrible trigger. If this suits you, you'll be well armed. No experience with the 225, but having owned both the 220 and the 226 find that the Sig is also a bit blocky for my tastes, but has better sights and trigger, and is a bit more expensive. Both are fine guns. I would take the Sig, any Sig, over the Ruger. I still own the 220, I made a present of the P95, and traded the 226.
