It might not be pertinent for collectors, but I knew some GSP troopers back when these were issued and they were happy with them until they started having lack of penetration problem through vehicles, especially glass obstructions. As I recall, upon the revolvers' mass replacement those that weren't purchased by the troopers were sold to a "cop shop" in Dekalb County. (Unless those were 25-5s from Doraville? Sorry, didn't keep notes way back then!) The name of the store may come to me at some point. Or if i can locate an old friend who worked there...

BTW, I'm pretty sure the issue ammo was the Federal 225gr LSWCHP.

ETA: It would seem the supply store is defunct. Nothing pops up in the area with a Google search.
