Hi Expat(Jim). I saw the Sheriffs model last night when looking at Cabelas site so is that the same as the 51 Navy? I really don't know much about the BP pistols. I only have one, An old Richland Arms 58 brass frame Remington I have never fired. Its a big honkin' sucker I would hate to tote around on a belt. Thats why the little Police style 36 Remington I linked to looked so good to me. And the short barreled 51 should be a little lighter than the long barreled 51's. I think.
