Any reason you want the Walther over other 380's. Not trying to change you mind, but I have been real happy with my Bersa Thunder 380CC. I have about 300 rounds through it so far without a hiccup. And the Bersa's are much better on the wallet. But they are going up in price as more people find out about them. But you can still get a new Bersa 380 for the price of a used Walther and possibly still have some left over.
I have the CC version, which is slightly thinner, basically no sights, flat mag, and a few other design variations compared to the regular Thunder 380.And it does hold 8+1 vs 7+1 in the regular Bersa Thunder.
Again, not knowing your intentions, just throwing that tidbit out there. Most that look at the Walther's end up looking at the Bersa's as well to compare. Good luck with your search. The Walther's are nice guns.
