Can you share some pictures of your jay scotts? I was looking at jay scott as well. Only ones I can find have checkering in a contained patch not all the way to front of the grip. Also the jay scotts have a hole for magazine release. The ones I want don't cover the magazine release.
They look similar to Harrett
They do look like Harretts I have for k frame revolver. But I can't find any for model 41 or any old advertisements for them either.
