My local dealer has a Sig P239 in .357 Sig. I've never owned a Sig or any pistol chambered in .357 Sig. I like the feel and size of the P239. Any recomendation on the .357 Sig? I am leaning toward the p239 in .40S&W due to ammo cost and availablity. I welcome your opinions and ideas. Thanks. BTW, the cost of the p239 in .357 Sig out the door is $500. Good price?
