I bought one for my wife a while back and have shot it a bunch. Let's see...
The Good:
-small grip fits very well in small female hands. it's also perfectly comfortable in my average sized male hands.
-trigger and sights are decent
-recoil is very, very low. it barely pops more than a .22
-slide is very, very easy to rack. if you have hand strength issues, this right here may sell you on the pk380.
-it's light.
-it's honestly fun to shoot. if 380 were cheaper, i'd bring this thing to the range with my every time.
The Bad
-you need to use a tiny plastic tool to field strip the gun. really? how dumb is that? will walther send you a new tool after you lose it?
-it's as large as single stack 9mm's, and you're sacrificing a lot in terms of ballistics by going with a 380 instead of a 9mm... but modern 380 really isn't that bad anyway.
The Ugly
-it's DA/SA, designed to be carried with the hammer down in DA... but how do you get the hammer down? look at that lever right there, that must be a decocker, right? oh no. the lever simply raises a plate that blocks the hammer from hitting the firing pin. to decock this gun, you flip the safety on then PULL THE TRIGGER. whoever thought this was a good idea should be kicked in the nads.
