I have a West German P228 I love, bought used with little wear or use and which, as I understand, is the double stack (13+1) version of the P225 (8+1), the two being identical in size and weight excepting the P228 is slightly wider to accomodate the double stack. Haven't shot the P225, but I have shot a few other P series and liked them all. It is also my understanding that performance of the P228 is similar to the P225 so I'll give you my experience FWIW.
The only downside I have seen on my P228 is that the slide, which is their standard matte finish, is susceptible to sweat staining and even light surface rust (easily removed) which is typical. They also have a K-kote finish that is much more corrosion/moisture resistant so it just depends on what finish the slide has. There may be other finishes of which I am not aware. Besides that, I have no complaints or problems with it. It has always gone bang when I want it to, never when I don't. Not a single FTF or FTE in 2k+ rounds. It is my fiancee's favorite of my small collection as it has little recoil and quickly comes back on target. It is very accurate at self-defense ranges and supposedly accurate to 100 yds (although I do not know from experience as I would be lucky to hit the barn at that range).
Mine had hogue rubber grips on it when I bought it. I replaced them with factory plastic grips which I prefer for urban conditions Lots of people comment on the factory screws coming loose or being too soft to tighten down well. I purchased a set of hex head screws for it based up on this, but have never installed them as I have had no issues with the factory flat head screws.
I especially like the factory sights which are sort of like the heinie straight 8s. Wide notch at the back with a white square, large white dot at the front. Very quick to acquire, easy to use with both eyes open, easy to re-acquire after the shot, but useless in the dark. I much prefer them to the 3-dot XD sights and can acquire/re-acquire the target much more quickly with the Sig's sights.
Hope that is of some use. From what I can gather, the info should pretty much all translate to the P225.
