Didn't somebody used to make custom 5 shot .44 specials on Ruger "six" frames?
it was call the .44 ASP and was designed to ride on the coattails of the Seventrees ASP which was the first production sub-compact S&W M39.
i thought it was marketed by a compant named Armorment Systems (ssoomething), but they didn't build it...i'm thinking it was put together by Mag-Na-Port, but i'm likely wrong
