Original SA revolvers didn't have much of a safety. If you loaded all
chambers and then dropped the gun, it could easily go "bang". The cure was
to load it one less than max, and rest the hammer on the empty round. Even
then, reloading was tricky - we get the term "going off half cocked" from
these guns.
All Ruger "New Model" single actions, which means everything made after
1973, has a fully modern transfer bar safety. There is NO safety difference
between such a Ruger SA and a modern DA revolver. Rugers before 1973 can be
retrofitted with a transfer bar setup by Ruger for free, but as the trigger
isn't quite as slick, many people choose not to do that and rely on extreme
caution and religiously following the old-time 19th century safety drills.
In the shooting sports that use SA revolvers, you're required to load one
less than max regardless of whether or not your SA has a transfer bar. That
way, people shooting Colt SAAs or the various Italian clones of same are at
no firepower disadvantage from a guy shooting a Ruger SA. But for street or
woods carry, it is 100% safe to fully load a Ruger transfer bar SA to the
max.
> * Performance
Because the SA cylinder doesn't "swing out", reloading is slower but
accuracy can be higher. The most accurate revolvers in the world are the
Freedom Arms large-frame SAs, and any number of gunsmiths can get serious
accuracy out of a Ruger new model SA action.
The SA action is very strong. All of the most powerful handgun calibers
were developed on customized SA revolvers, almost all Rugers. The premier
gunsmith doing "handcannons on Ruger frames" is John Linebaugh:
http://www.sixgunner.com/linebaugh - look under his "gun services" and check
out the ballistics on the .475Linebaugh caliber on up through the "Longs".
He's getting these horsepower levels WITHOUT modifying the Ruger SA frame.
Which means in stock .44Mag or .45LC, it's close to impossible to blow one
up with anything short of a max doublecharge.
One more SA advantage: the traditional SA grip designs were meant to be
fired one-handed. They "roll in the hand" - when you use them two-handed,
you can deal with recoil levels far beyond what any other action type can
handle. And what Ruger calls the "Bisley" grip is even better at major
recoil control - that grip is really an old Elmer Keith design from the
1930's, it's not "old west" like Ruger wants people to think, but Elmer
REALLY knew what he was doing
.
Per a lot of reports, if you fire hot .44Mags in a Ruger SuperRedhawk
weighing about 50 ounces, and compare the felt recoil to firing the same
load in a Bisley Vaquero .44Mag weighing 39 ounces, the difference in
comfort is night and day and it's the Bisley that *wins* despite being
lighter. The more compact frame drops the bore down closer to your wrist,
and the grip soaks up recoil better. Now, shot-to-shot speed on the SA will
be slower unless you put some serious practice in.
You really have to make a commitment to mastering the SA, it's much more
difficult than the "grab it and pull the trigger over and over again" drill
on a DA. But there are rewards! More power in a smaller package, and with
a LOT of practice, the fastest draw/fire sequence of any handgun type.
> * Pro's & Con's of both type of action
The DA is easier to get a fast string of shots off with, and is much faster
to reload. But accuracy, size efficiency, toughness and recoil control all
go to the SA. They are also very easy to modify, and because Ruger stayed
with the same mechanism from 1973 to present the aftermarket support is
extensive:
