Have many of you had any dealings with the customer service groups of either Smith & Wesson or WaltherUSA by using email? If you did, what was the typical response time for a question in days or weeks. The reason I am asking, I bought a new Walther PPK/S for the wife, which she just loves, lucky me. I have a problem with extra mag, I sent a email question to them over a week ago and have not received any response or confirmation that the even received the initial email. Today I re-sent the request just asking if they received the first one. I used the address they have listed in the manual.
