The 239 is a great accurate little gun. Mine never failed me. Its my second faviorate 357 sig on the market for ccw next to the glock 33.
The 357 sig hits as hard as the 357 mag with the recoil of a 40 sw. Its reliable, amazingly accurate and an overall great round. Compared to a 9mm its more powerfull, compared to a 40 sw its more accurate and just as good a stopper, compared to a 45 acp it fits in a smaller gun with simular stopping power.
I put the 40,45 acp and 357 sig all in the same ball park for stopping power with the 9mm in a close runner up position.
