Is/was the 25-2 Jovino a modified gun, or a factory special edition? SCSW 3rd Edition doesn't mention it. Ditto for the Austin Behlert gun. They do identify a 3" RB 45acp model 25-3, 100 produced in 1977 for Lew Horton. I seem to recall some 45 Colt "Effectors" advertised in Shotgun news some years ago also.
