I have a 239 in .40 and love it. At 30', I can put 15 shots (7+1 in first mag, 7 in the second mag, new mags started in DA mode)in under 2" easily. If I really try, I can group 12 out of 14 in just over an inch, one big hole, with the occasional flyer. The flyers aren't the DA shots, but usually toward the end of the string, and I can call them as flyers. The flyers are only about 1" out of the group, but I still like only 1 nice big hole :) 239 is very comfortable to carry, and the Hogue finger groove grips are awesome as well. I also have a 686+ 4", and can get slightly smaller groups with that at the same distances, and I seem to be more consistent with it with less flyers. Just haven't found a IWB holster I like for it yet. 239 is heavier than the baby glocks IIRC, but it shoots very smoothly and well, the weight is a plus in controlling the hot .40 and making quick follow up shots. I had a glock 23, and the 239 is similiar size, but heavier, and i like it much better.
