Yeah, the Mod 58 is an N frame revolver and will fit any holster for N frames like the 25/625, 29/629 and 57/657. Yours is simple a fixed sight N frame in .41mag...and a damn nice revolver. Congrats.
I had the money till they made me pay
Then I had the sense to be on my way
I had to stay in the underground
I was in the house when the house burned down.
