Like George said in his article, the 229 SAS is soft shooting for a .40. It is much nicer to fire than my glock 23.
The trigger is very nice. Smooth and not too heavy. Longer and heavier feeling than my glock, but when I took mine to the class the other weekend I didn't have any issues with the trigger.
I did, however, discover that I don't like the rear site on the SAS. I am used to the three dot site system and find I prefer that. The SAS has a single white bar under the notch on the rear site. I plan on swapping the rear site out and putting on a rear night site to go with the front night site.
The grip is slightly longer than my glock 23, though it looks much longer when side by side. The round capacity is 12+1 where the Glock 23 is 13+1. I guess a function of magazine design, no big deal for me. The wood grips actually come down a bit past the end of the frame to form a small mag well. I didn't find the grips to be too fat for my hands. I am tall and thin with hands to match, so YMMV. I did like the swell up near the slide stop, as it helped prevent me from riding the slide stop and having the slide fail to lock back on an empty magazine.
The other thing I discovered that I wasn't completely happy with was the slide serrations don't go all the way to the top of the slide. I guess this is particular to the 229, as the other models have the serrations going all the way. I could get a grip with little issue on the 229, but have a much more positive grip on the ones with full serration. I might look at the 226 SAS and compare the difference in size.
Here is a picture of the 229 next to my glock 23.
