I'd have to vote for the Sig p238 .. just got a Scorpion, which is a bit beyond your price range. But the basic gun is close, and the extras are amazing. Night sights, two mags, paddle holster (which I don't like, but you might). Had it to the range today, amazing accuracy at 7 yds (200+ rounds, all in the center two rings of a 12-inch Shoot'n'see target, zero failures of any kind), very light recoil and a real thumb safety. I tried a few others -- LCP, Glock 42, and handled the Kimber. The night sights helped clinch the deal, but the overall feel and obvious quality sold me. My pocket holster arrives tomorrow (a Nemesis) and it becomes my summer EDC.
As for your concerns, the Sig is very narrow across the slide and appears it will be far easier to pocket than my PM9. It weighs a bit more (around a pound loaded) but that is a great help with recoil, which means you're back on the target faster. The beavertail, of course, is near the middle of the backstrap and will not interfere in any way with the draw, IMHO.
Have to disagree with Mr. DeShivs ... I pocket carry the PM9 often and the Sig is smaller and far easier to conceal. I'm 5-10, 160 ...
