I got caught up in a S&W recall when they wanted 6 years of PPK/s production returned. I lucked out sort of as I just bought mine. I didn't even fire it yet but when I bought it they had a buy one and get two free mags coupon going on. The day the recall was put on their website was the day I went to it to claim the mags so I sent for the return label. How they handled it and probably how this one will go is first come, first serve.
When I bought it I knew going in that many were problematic but I did a lot of reading and the best I could come up with were 3 possibilities. The return spring was inserted backwards with the tight end forward, the ammunition was wrong and should be 90-100 grain, FMJ and/or the ramp needed polishing. The first two were easy enough and I was going to polish the ramp but then the recall happened. They said on the phone to place a note in the box as to why it was returned so I took a chance and wrote recall and ramp needed polishing. Even though mine was one of the first returned, it took a couple months to get it back. They said the delay was do to getting replacement parts (and probably to train a temp group of people to do the replacements) but still, mine was also one of the first to be shipped back to the consumer.
When I did get it back, the ramp looked like a mirror. Not a mark on the PPK/s except the stamped dot on the top of the beaver tail to signify the recall was complete. I love that little guy, aims like a laser, never had any failure of any kind no matter how loosely you hold it and no problem to get all blacks at 10 yards rapid. I use S&B, FMJ .380's. I think European runs hotter than USA ammunition in .380's. I use ammunition that a gun was designed for and that basic design is 100 years old. I should mention that it is the only pistol I have that I exclusively shoot right handed due to the decocker position, I'm left handed but I do use both hands with pistols, takes a bit of practice.
From peoples postings at the time, especially the late to the party people, they weren't to pleased as to what they got back.
