If not already mentioned....try Jack First in Rapid City, SD. Their website is rather basic, but you can get the phone number. Just about "anything" gun you try to find now is scarce. Numrich Arms are usually my go-to people, but they have gotten very sluggish lately.

S&W told me they were sending me some parts "that day" when I called them. "That day" was 2-months ago and I still don't have any parts.
