mg357, I purchased a Walter ppk over 1 year ago. The first time I fired it, nothing but ftf and jams. At that same time, a recall was issued, so I contacted S&W, they provided ups instructions and label and off it went. I included a letter about the malfunctions and requested any help they could offer. The pistol was gone about 3 months due to the influx of a lot of pistols. Long story short, finally got a chance to put it through its paces with quality ammo today and it worked like a charm. Understand that it is not a comfortable weapon due to its design, but with practice it can be a lot of fun. I do carry it concealed, especially on days with very light clothing.
