Walther is re-releasing the PPK in .380 this year ;-)
Now that would be an interesting acquisition. I had one of these 10+ years ago and let it go...I did like it, abeit it was a tad on the heavy side for anything other than waste-ban carry.
Oh, and I have owned two (2) Bersa Thunder .380's back in the late '90's...they were great shooters as well!
