The top gun is a Model 58 with a Model 1955 barrel cut to 4" and a Model 27 cylinder chambered in 45 S&W. Doing load development work on the cartridge now but preliminary tests show the gun has a lot of potential. The grips are Spegel checkered extended boot grips in Makassar ebony.
The middle gun is a Model 58 with a Model 1955 barrel cut to 4" and the cylinder chambered in 45 Colt. It shoots my standard 45 Colt load very, very well. The grips are Spegel checkered extended boot grips in Cocobolo.
The bottom gun is a Model 520 with a Model 29 barrel cut to 4" and the cylinder chambered in 44 Special. The grips are Spegel checkered extended boot grips in Makassar ebony.
The ribs on all three barrels was milled and matted to match the original Model 58 barrel rib contour and the front sight profile was changed to improve the sight picture.
