I have a 40 caliber P229 Elite Stainless and a 40 caliber P239.
Frankly, the P229 cycles so smoothly in recoil that I find it a bit boring to shoot. As for the SRT trigger option, the short reset does make it easy to use in speed drills, however it also has a very long sear creep. Sig had to lengthen the sear engagement surfaces because during development it was found that the standard length sears would permit the gun to double or triple fire if the shooter held the trigger right at the reset. As a result the SRT trigger has enough sear creep to drive a Bullseye shooter straight up the nearest wall, I've measured the creep at 0.070 inch on my P229. In adition after about 500 rounds downrange and a ton of dryfiring the DA trigger is still quite heavy and very gritty, another somewhat common complaint about the SRT trigger option. Bascially, it's a great gun for Action shooting or speed matches, however the SRT trigger isn't well suited for precision shooting.
I'll also point out that Sigs with double stack magazines have a grip that is a bit overwide for most shooters. I have slightly above average sized hands and I have to "sidesaddle" the grip on my P229 a bit to get good trigger control. Sig has recentlly addressed this issue with a new style of grip in the E2 series that are snap fit to the frame instead of using screws and feature a reshaped rear surface. Anyone with average to smaller hands should take a long hard look at picking up one of the E2 series. However, currently the E2 guns are only shipping with the thinner short reach trigger and that may cause the reach in single action to feel a bit cramped for those with average to longer fingers. If so, you'll need to have the standard reach trigger installed to make it fit properly. BTW, the design if the E2 components is such that the older Sigs can be converted to an E2 configuration, in Europe these kits are reported to run about 150 USD, in the US these kits are LEO only and something like 105 USD. Note, installing the E2 kit requires a new hammer strut, mainspring, mainspring seat, and the grip, it's not a simple grip swap. However, Sigs by design are very easy to work on, for a Sig Armorer it's probably about a 5 minute job.
As for my P239, it currently has about 2200 rounds downrange. It's also an older non SRT model and the sear creep measures at a very crisp 0.019 inch. Downside is the reset is noticeably longer, however I do so much shooting with revolvers that a long reset doesn't bother me a bit. In addition, it's got enoough "pop" in recoil that I don't see any need for the speed capability of the SRT trigger option. Fact is that my P239 is my favorite semi to shoot, the slimmer grip fits me perfectly and it's a superb point shooter. I'll also note that I've only had one single failure with my P239 and that was a dud primer in a round of 40 caliber Federal Champion. As for it's accuracy, when I'm shooting well it's simply stunning.
Bottomline, Sig's in my experience are totally reliable and very very accurate for Combat pistols. However, I've found that Sig's also need a bit of "fitting" to the shooter, especially the double stack models. I've also found that Sig's need to be run wet, I prefer to use Lubriplate grease on mine, it's cheap and minimized wear. I'll also point out that any Sig not being used at he range should have the bore protected with oil, Sig does NOT use stainless steel barrels and they will rust, I now have a spare barrel for my P239 due to learning that lesson the hard way.
