The only good things about this pistol are it shoots nice and feels good in your hand.
Everything else sux.
It's a double/single action, but it really doesn't have a decocker, you have to put the safety on and drop the hammer over a blocked firing pin by activating the safety which is nowhere near your thumb. So you really end up using your off hand to do anything with the safety. Therefore, if you carry with the safety on, you'll require two hands doing different things in order to fire it. One hand to point and shoot, the other to disengage the safety. Or you could just play it safe and carry it with the hammer resting on the firing pin without the safety on so you don't have to concentrate on multitasking if you need to draw and shoot really quickly.
In that case, you really shouldn't worry about carrying any extra mags. Even though you'll probably need several, (after all, it is a .380) you'll probably die of blood loss by the time you figure out the trick magazine release lever thingie in order to put in a fresh mag. Evidently, a push button is entirely too easy and makes changing mags too simple and effortless. In order to avoid the problem of quick mag changes, Walther has developed the half trigger guard flippy down thingie to mix it up a little and keep things interesting.
If, by a stroke of luck, you do survive a shoot-out, you aren't out of danger yet: Upon cleaning it, you'll most likely be killed trying to reassemble the recoil spring.
The only reason I would ever purchase one of these P.O.S.'s would be if I won the lottery. I would buy a bunch to use as targets and shoot at them with all my other firearms.
