I've carried a P239 for many years. Originally in .40, I got a Barsto 357 SIG barrel and mags for it.
Mine is DAK. I have to carry a Glock at work, so, I intentionally stayed with a no de cock no safety trigger system. But, that's just for me. The DA SA is fine too if that's what you are used to.
Off duty I carry appendix. (I wont carry a glock appendix) For me, the P239 rides perfect. I've tried a lot of other guns but always come back to the P239.
If you look at the stats, a P229 is just a tiny bit bigger, but carrying it the way I do, it's radically different.
The P239 is exactly just big enough to shoot like a full sized gun and just exactly small enough to carry comfortably.
