my brother carries a 239 in 40 s&w, i had one years ago but it was a double action only and i dident like it, i shot my brothers and loved it, i was trying to trade for one a couple of weeks ago but couldent find anyone that would trade, i will probably end up with a 357 sig 239 at some point again, excellent quality gun!
Summit Gun Broker has 239 SAS CPOs (only in 357 Sig) for a very good price.
