Do a search, I've posted on this a few times before.

Short story:

1) It doesn't have the heirloom potential of the original Walther pistols;

2) It's a pistol people love to hate, due to the use of Zamak alloy in the frame and slide - but most of those haters don't actually own one; and

3) Mine shoots just as well as my Walther PP in .22 LR, with the advantage of a much better magazine design, and much more available magazines at inexpensive prices.
