Let's see.. I had a Walther P99 and sold it..
Likes...
It Looked awesome
It was 100% reliable
It was easy to field strip
It was easy to shoot well
It felt great in my hand ( like it was custom molded)
The loaded chamber indicator
Interchangeable backstraps
Interchangeable front sights
All the controls worked flawlessly
Came in a cool handgun case with molded foam inserts
Dislikes...
Decocker button on the slide was an awkward reach for this lefty.
The factory sight weren't very good
The DA trigger was well, horrible ( I didn't have the patience to wait until it got better) The DA trigger pull was loooooooong.
Bottom of the trigger would bite the "edge" of my trigger finger
That ski ramp thingy under the trigger..
The high price of factory Hi caps.. ( $100 each, OUCH!)
Again, these are just my personal observations, you results may vary.
I'm going to wait for the P2000... and wait ... and wait.
