My first BHG was a 4.6" SS Vaquero in .45 Colt followed by a .357M version a few months later. I had to have a .44 Special BHG, but none were available. I bought a 4.6" SS SBH the same day as the .357M Vaquero BHG, hoping to swap gripframes. When that was a no-go, due to the wide variation in frame thickness, I ordered a QPR BHG frame & grip and fitted same to the SBH, making the gun below. I added a .32 H&RM BHG - all had black Micarta grips, SS, and 4.6" barrels. I sold the .357M to a friend, the other two - and a 4" .32M SP101 - to another guy, and my homebrew SBH was traded for a new unshot Seecamp .32, holster, ammo, & cash - for my wife. Within days, my Ruger collection was gone! I bought a new 627 Pro and a NIB trade-in 64 with my ill-gotten gains - and made my wife happy with the pocket piece she wanted.
I miss the SBH/BHG the most. A tad heavy, it was still fun with wimpy .44 Russians to regular Specials. Add some oomph, especially real Magnums, and that muzzle would point skyward afterwards, the ball like grip with slick Micarta 'rolling' in your hand. Not to worry - the SBH hammer digs into your hand, limiting the 'roll'.
BTW, I hate the BH hammer - love the Bisley. The SBH hammer is a drop-in and a nice hammer. The Bisley hammer has some non-functional backside metal to file/grind away before it'll fit the non-Bisley gripframes. Adapt the part, not the gun, of course. All but the .32 SSM got a free-spin pawl, the SSM getting a bit ground off it's pawl's leading tooth - see the Ruger forums for this. It was done during commercials while NCIS was on one night - with only the cylinder removed. Being a chicken heart, I had two spare pawls... just in case.
I thought I would miss my Ruger purge... thus far, only the homebrew BHG/SBH. I love my S&Ws, even the 617 I sacrificed my MKII for. YMMV.
The .458 Lott, a left-over from another Ruger purge (#1H in .458 Lott - beautiful furniture!) won't fit the BHG/SBH. Sigh!

PS The BHG frame, like the shortened BH frame (The other SSM grip.), doesn't have room for that hammer lock Ruger uses now, probably why they are gone.
