The RD185838P converts your Pietta 1858 Remington Navy revolver to fire the .38 Special cartridge loaded with hollow base or heeled type bullets. You can also use 38 Special Hollow Based Wadcutter ammunition. To overcome the larger bore of the original barrel, it is recommended that you use hollow based or heeled type bullets.
Please see our cowboy ammuntion selection.
(If, after installation, you are unsure of the fit, please take your revolvers to a competent gunsmith or contact R & D Gun Shop to make sure you have the cylinder installed correctly.)
