Well I have a G23 that is my EDC, I also have a P228, same as your P229. The Sigs are great machines no doubt. One poster made great sense in saying you have great carry guns already. The 228/9 line is a little bulkier to conceal than one might think. I can hide my G23 way easier than my P228. The 239 is way too heavy and big for what it is. I personally think the Glock 21 is your best bet, and cheaper too, allowing more money for ammo and holsters etc. You wont be dissapointed with a Sig in any form though.
