Been some time ago but a guy wanted my 27-2 (both 4" & 5") more than I did so I reluctantly sold them. I'm still wanting to replace the 4" to accompany a 3.5", all in -2 series but in my quest, I was able to locate and purchase a 4" 27-7 (8-shot blue no-lock, 1 of 100 produced for Bangors).
I might never had found the -7 if I'd not sold my -2 and wanted to replace it.
