The entire F Series is designed for non-defensive but playful and sporting applications, configured for target purposes, with precision sights and larger fixed barrels.
This is a basic blowback pistol, having a heavy barrel fixed into the frande and a slide wich traps the recoil spring beneath the barrel.
The basic lineup remained the same with the F being the 4" version, the Sport the 6" version and the Target a 7" version. All pistols seem to have had the same sights, which consisted of a micrometer adjustable rear and a replacable front blade. The shipped front sight is a triangle when inserted, flat on the back. The screw to remove is on the right side of the gun.
All FR series pistols have chrome or blue finishes.
The model F was itself made in a number of variants, most of which are four basic series.
