Ruger P-series pistols are designed to be tough and for the money, very accurate. I have a P89 and it is my home defense pistol. I have shot a manual safety P90 and it's a very good pistol and more accurate than I am. The versions with the Hogue grips already installed (H after model #) are the ones to get. Hogue did a great job with Ruger in getting the grips to make the pistol fit easily in your hand.
Ruger states in their instruction manual that their "P-series pistols are compatible with all factory ammunition loaded to US industry standars, including high-velocity and hollow-point loads, loaded in brass, aluminum, or steel cartridge caes. No 9mm x 19, .45ACP or .40 S&W ammo made in accordance with NATO, US, SAMMI, or CIP standards is known to be beyond the design limits or known not to function in these pistols." That says a lot about the strength of Ruger pistols and Ruger customer service is supposed to be fantastic. Hopefully, I'll never have to find out but knowing that a company will bend over backwards to support their product is a pretty good deal to me.
