Great points Cuervo, the P250 is a range only firearm.. I found it a little too large/thick to carry comfortable. I prefer IWB. So the single stack factor on the 239 seems like a better route for carry to me. I actually own two of the P250s so I have no attachment. The one I have is the compact model, stainless slide. The 239 is the same caliber, both 9mm. Standard model 239 as far as I know. Definitely not a tactical model, does not have dak trigger, it is da/sa.
I actually really like the DAO trigger on the 250, i am a revolver shooter so I enjoyed having a semi with a similar double action trigger. DA/SA is about the same for me as the DAO. Either way works. The only thing about the 239 that I see from first glance that I don't like is the aftermarket grips on it. I believe they are something like hogues, thick rubber with finger grooves. I will probably put something similar to the thinner factory grip panels back on.
Thanks for all of the replies so far, if nothing else it has confirmed my feelings on the trade.
