Sigs are good guns. I'd add a 229 to your list and remove the 250. For the money you spend on that 250 you could get a Glock 19 or something else and they would run far better. Though your list seems more for ccw then OC.
I prefer a Walther PPK/S to the 239. Thinner and much easier to conceal. Get a pre-Smith & Wesson one though. Interarms, Manhuirin, or W.German ones are the best.
