Mrs. 3-5-7 bought a twenty-gauge S&W 1000 seven or eight years ago, primarily because of the lightweight aluminum-alloy receiver. When we called S&W to inquire about an owner's manual and parts, we were told that they had no more parts...but they DID photocopy the parts list and operating instuctions and send it to us. After just three or four boxes of shells thru her new toy, it began to malfunction...not "feed" after the first shot...and then it wouldn't even eject the "empty". I disassembled it--keep in mind it was in excellent condition on the outside--and it looked like it had fired at least a pickup truck full of shells...and had NEVER been properly cleaned!!! There was a "sludge" all throughout the gas system...like someone had sprayed some kind of solvent or cleaner in there, but not bothered to go any further. After a THOROUGH cleaning, it became obvious that several of the components of the gas system were worn out...and replacement parts were not to be found, even back then!!! Cleaned it up as best I could, and she traded it on an 1100 "Youth Model" at her first opportunity!!!....mikey357
