Nice catch and nice price!!!

I've owned a couple 20's and KY Imports brought in a bunch a few years ago.

An interesting gun from an interesting period.

BTW, ISP in its infancy issued them, but they are rare as hen's teeth. I actually did some digging and spoke to an armorer who said the Troopers were allowed to take their service revolvers with them when the HD's were rotated out in the early '60's. I believe they had to purchase them from the Dept, IIRC.

Unless yours is import marked, could it be an old ISP gun?????
