I bought one one of the 239s in 9mm when they first hit the market, I have since acquired barrels and magizines for the .357 and .40. All function well, and the gun is an excellent shooter with either barrel. tho the .357 seems to be my favorite. For a carry gun, I pack a Sig 245 (scaled down 220), like all of the Sigs, they are absent of a SAFETY lever, switch, button, but I carry with a round in the chamber and feel quite safe doing so.
I highly recommend the Sig, and am sure you will too once you have some experience with it. If/when you butt is on the line, you will be glad you are packing a Sig.
