FWIW, I know this is a bit of a necro-thread at this time, with me being the latecomer to the party. However, I felt I needed to reply since I own 2 of the weapons in question. I own 2 Walther PPS's in .40, and the Beretta 9000 in 9mm. The Beretta is a great weapon, but cannot hold a candle to the Walther.
1. The Walther disappears on me, the Beretta screams, "Look, he's got a gun!!"
2. I don't care for the blocky grip on the Beretta, The Walther comes with 2 backstraps of varying thickness.
3. The Walther is INFINITELY simpler to field strip.
4. I don't really care for the decocker on the Beretta. Walther's Glock-like safety has spoiled me.
5. Recoil difference is negligible.
For my money, the Walthers were more money, but you get what you pay for. Don't misunderstand, I like my Beretta, and would trust it, and have no issues with it's quality or accuracy. But the Walther blows it away.
*sigh* I guess I'm just a Walther snob.
I do not frequent here very much, (this is my 1st post here) but can be found on concealedcarry.com, and ppstalk.com under the same screen name I use here. And I have set my defaults to accept email if anyone has any other questions. I will try to be of as much help as possible.
