I would like to find a 5½" someday. Thanks for the clarification on the box!
I have a few ruger vaqueros & blackhawks in 44-40 38-40 32-20 wish they would have done a 25-20.
I always wondered why Ruger didn't and Colt never did either. I was looking for a 25 caliber barrel like a Hawkeye take off barrel. Couldn't find one. The .218 Bee is virtually the same but in .22 caliber. So I rechambered a single six cylinder to .218 Bee (I had to shorten the case neck a bit to fit in the 22 cylinder. Shot it in a 6 1/2" single six. Accuracy was not that good. I was pretty sure it had to do with the bullets I used and/or the rifling twist rate.
I moved on to a convertible Super Single Six .32 Mag/327 FM/.32-20 (also shortened case necks .040"). That was a success! Slight enlarging of the loading gate chute was needed for the larger diameter .32-20 case rim.
Did a couple of those for friends as well, one of them an Old Model Single Six .22 which required a conversion to center fire firing pin location, and greater enlargement of the loading gate chute from .22 size to .32.
One was a Stainless Vaquerito, but with the standard size grip, not the short grip. I did one for a guy who wanted a single cylinder that shot all 3 rounds. I was surprised how well it worked. Kinda' like shootin' .32-20 and 32 Mag/327 FM in a NM .30 Carbine cylinder.
Super single six .32 mag/.327 FM/32-20. Bisley hammer, grooved SBH trigger, Cyl pin modified to be retained in frame when swapping cylinders. Colt ejector rod. Stainless steel grip frame.
The cylinder pin (OM pin shown) in the background has had another cannelure added near the back end which retains the pin when making cylinder changes in the field so you don’t have to pull it all the way out or worry about it dropping in the dirt.
