I would never, ever, EVER EVER EVER carry in a purse.
People would look at me funny. A man carrying a purse and all. (hehehe).
I'd recommend a little holster even for pocket carry. Keep that trigger protected. There are cheap pocket-carry holsters out there. It's still cool enough too that you can get an el-cheap-o hip holster and conceal it pretty well under baggier clothes or a jacket. Gander Mountain out here had some $15 IWB holster. Better than nothing. And a whole lot cheaper than hole-in-leg syndrome, or a stolen gun. In all seriousness, I'm not a fan of off body carry. Snatched purse, or even just something shifting; remember fine motor skills like opening a zipper or manipulating a pistol buried in a purse will go by the wayside in a life-or-death situation. If you've ever been in a situation in your life where you have been truly terrified, and tried to open a lock or get your key in the ignition or something like that you'll know what I mean. If you're terrified, shaky, potentially going to die if you don't react soon, are you going to be able to get that zipper open and find your gun, quickly? With a holster, even a cheap one, you can make reaching for the gun instinctive, and it doesn't require fine motor skills. Just grab the grip and pull. Once the gun is pointed down range, put your finger on the trigger. If necessary, squeeze.
My $0.02.
