I belong to several forums.

The Ruger Forum is the most political and the most intolerant (i.e. "Rude") if you disagree with ultra-conservative. There is no middle-road over there. They brook no disagreement. It is fun to ruffle their feathers sometimes, though.

The S & W is "middle-of-the-road" and most enjoyable. We get some healthy discussions here (a few get heated) but we generally treat each other with respect. Many interesting and diverse topics, also.

The Colt forum is more informative on all things Colt. More "high-brow" and very much into historical facts. Limited on other issues. You do have to choose carefully WHERE you post. Your question would likely be best posted under "Revolvers". There are several guys who make cases over there.

Regarding the foam: There are several places I've seen on the net who have the "pick-n-pluck" type of foam inserts. Sorry= can't remember where.
