I’m looking for a leather OWB thumb-break holster to fit my new 66-8 with 4.25” barrel. I’d really like to have that last 1/4” of barrel covered. I carry this gun in the woods.
Thanks.

check Black Hills Leather I think he will make one for you at a reasonable price. Hs work is very good

I have three 1791's and they are amazing.

Hi There,
You might want to look at 'wrightleatherworks.com' . I had them make me the Marshal model for my 66-8. It fits perfectly. However, it is not a thumb-break. Just offering you another choice. Best of luck,

AL.

Thanks to everyone for the responses. I went with the Triple K 570. It looks like it will do the job.
