I own a P239 and really, really like the firearm. Nice trigger, well balanced and Sig Nite Sights. Mine is chambered in 357SIG. Mags are available through Top Gun Supply. I bought 4 "used" police mags that had never been out of the plastic wrappers for a very good price. I carry mine often, usually in a DeSantis Nemesis in the inner pocket of my cargo shorts (I live in FL). Some complain about the price of the ammo. I bought my first 500 rounds from Georgia-Arms. They sell in quantity called "Canned Heat". Very good stuff. 1300fps. That gave me the initial casings to begin reloading. Good luck to you.
