S&W is usually closed for the Holidays, and should be open again on Jan 3rd.
Not a common problem on the J-frames, but not unknown. They'll take care of it.
I have 5 J-frames, myself, and while a couple of them required some repair/correction when NIB, afterward they've been fine. One of them was corrected by the former S&W revolver armorer for me, and the other one I repaired myself after attending the armorer class.
I have a Ruger SP101 DAO 2.25" revolver, as well. It's an older production model. I had to correct a problem with it that caused it to frequently seize after 1-2 cylinder loads of Magnum rounds, but once I repaired the problem it's been fine for several years. I used to carry it in a pocket holster in a bulky insulted vest, but no more. It's heavy and large enough to realistically be a belt gun for my needs.
I know a number of LE firearms instructors who carry one or another model J-frame (most of whom are older revolver shooters). Some of the younger guys are discovering the advantages of the venerable J-frame for off-duty & secondary weapons. The J-frames do, indeed, seem to be experiencing a resurgence of interest among the younger generation of cops, as well as private citizens.
Unfortunately, the very attributes that make them so attractive for their roles also make them harder for most folks to shoot accurately & effectively. Even folks who shoot larger model revolvers often have to invest some extra training & practice in order to wring the best performance from the little wheelguns.
I had to dust off my earlier revolver skills once I started carrying my first 642-1, since it had been some years since I'd been carrying my 649 & SP101.
I'm thinking about ordering a 6th J-frame sometime soon.
