I don't own one, because I'm not really a fan. It's a slightly cut down P229. The P229 is a fantastic gun... but they are fairly thick. With as short as the P224 is, it's just... weird. To me anyways.
If you're looking for a gun in that size, I would probably recommend the P320 subcompact, M&P 9c, or Glock 26.
If you really think the thickness isn't an issue for you, or if you really want a DA/SA trigger, then by all means, the 224 is a well made gun. I guess my train of thought is that if I'm already concealing such a thick gun, the minor difference in grip and barrel isn't really a big advantage over having a full grip on the pistol.
The HK P30SK/P2000SK might also be good options to look at.
