If you like the looks of that revolver, there is nothing about it which cannot be had in a Single Six.
That SBH looks fancy, but other than being an exclusive factory model, it’s nothing but a bare bones factory model with $38 Altamont Checkered & Engraved SilverBlack laminate grips, a short barrel, and a $100 rough country sight. Sure, $700 is a relatively decent price, and a guy couldn’t build a 7.5” SBH into that for $700, but if you don’t need/want the .44mag cost or recoil, then you don’t want/need a decent deal on a 44mag revolver.
Personally, I recommend switching your deposit, getting the Single Six convertible you were after, paying $38 to Altamont for new grips (or better still, paying $75-150 for true custom grips with REAL sex appeal), paying a smith $300 to convert it to Bisley, less the sale of your grip frame and grips (about $100-150), and decide whether you actually want/need the Bowen sight. In other words, build a .22LR convertible with all of the sex appeal you’re seeing in this SBH, but with the economy and shooter friendliness of the 22 LR/WMR you were initially wanting.
You will find yourself happier in the long run. You’ll have the cartridge(s) you wanted, less recoil, less cost, more practical fun, and also a sense of satisfaction and pride in owning your own semi-custom revolver, which is truly one of a kind, more deserving of the attention than the factory upclass.
Recognizing - that is said by a guy who is a die hard 44mag Ruger revolver fan. To add some context to a recommendation AWAY from this particular 44mag Ruger revolver.
