My P229SAS runs like a champ; very accurate and solid. Think SIG BlackSpecial of the pistol world.

When I handle it I am still in awe with the finish (how perfect and flawless it is - no crooked lines or flashing anywhere)
The design is almost perfect (my only complaint is the trigger return spring), otherwise it's a tank!
I enjoy tinkering too much and have already put in a 19# hammer spring and 17# recoil spring from Wolff - trigger feels even better now and the slide feels smoother (the stock recoil spring is so tight on the rod that I could hear it when I worked the slide - not an issue at all).
I've ordered/received all the spare parts I wanted for it as well as some extra mags.
I also bought a set of regular P229 grips to temporarily replace the wood for range use as they are thinner. I am now seriously considering buying all the parts I need for a SA/DA trigger group; that way I can swap between DAK and SA/DA whenever I like (and 15 minutes of my time).
I just ordered a Short trigger yesterday and am looking forward to its arrival; I'll post pics when it gets here.
So... in short... I do not regret the purchase and it is hands down the best pistol I've ever owned.
The only negative is the cost to me and the interest I pay VISA every month (Ugh, I need make more money).
I post all this info, because if anyone out there is a modding bastard such as myself, I suggest the DAK model as you cannot readily buy the DAK trigger group parts, but the SA/DA parts are very easy to get

just an FYI
