The case for DAO
In the Gunsmithing pages of
this site, I endorse the practice of rendering defensive revolvers
double action only (DAO.) Many people ask why, and I thought I'd
give you my thoughts on the matter.
Let's start with the usual argument for retaining single action
capability, which I call the "Walter Mitty scenario": the mythical
need for making precise long range head shots. Let's face it, folks
- this just never happens in real life!
However, let's say that you're having a Jack
Bauer kind of day and are now
facing just this scenario. Mightn't that be just a tad bit
stressful? Wouldn't that make you even more nervous, knowing that
you'll be trying the toughest possible handgun shot under the worst
possible conditions? With all that adrenaline now flowing through
your system, is this really the time that you want a light, short
trigger pull that is very easy to accidentally release? Not me,
bunky!
This is the reason for DAO: light single action triggers are great
on the calm shooting range, but pose a liability risk for
unintentional discharges under stress. As Massad Ayoob says, single
action triggers are great shooting tools, but lousy threat
management tools.
Now I I know what you're thinking: "OK, but I promise I'll never
use it!" I'm sure you mean that sincerely, but It's been well
established over the decades that people tend to do in combat what
they do in training.
It's human nature to practice what we're already good at, and to do
that which is easiest for us. At the range, it's not uncommon to
watch someone shoot a revolver at, say 50 feet and become
disenchanted with their groups. At that point, they usually switch
to the easier pull of the single action, and shoot that way. This
imprints their subconscious to use single action when they are
unsure of their abilities, and this may be what they revert to
under stress.
Once that act of thumbing back the hammer has become habit, another
problem crops up: the Hollywood-inspired (and reinforced) act of
cocking the gun to show the bad guy that you "really mean it!" I'll
refer you back to the second paragraph, with emphasis.
(Yes, I know you'll promise not to do that either. But if you've
told your subconscious that cocking the hammer is accepted shooting
technique, do you think it'll ask your conscious mind for
permission when the time comes - especially if decades of TV and
movies has told it otherwise? Of course not! "Besides", your
subconscious thinks, "if Tyne Daly can do it, why can't
I?")
Removing the SA capability eliminates the chances of any of this
happening. (If you make the conscious decision to carry a gun with
SA capability, I recommend that you attend the Lethal Force
Institute's "LFI-1" class, where you will learn how
to defend that choice - and counter any false claims that may arise
from it - in court.)
From a gunsmithing perspective, I've found that eliminating the SA
capability can, on some guns (Colt and Dan Wesson), give a bit more
leeway in terms of honing the double action. Without the need to
worry about the single action sear, the double action can be tuned
far more radically than is otherwise possible. In S&W and Ruger
guns, reducing the DA pull to the barest minimum (as some request)
will result in an unconscionably light SA pull - often below 32
ounces. Eliminating the SA notches means that this ceases to be a
worry.
Speaking for myself, I didn't start to shoot DA well until I'd
gotten rid of the SA capability completely. True story:
one day (many years ago), shortly after transitioning to shooting
only revolvers, I was participating in a match (Bianchi type.) I
was having trouble with missing those little round steel plates
they use for one stage, and it was making me madder and madder. At
one point the buzzer sounded, and I drew the gun (a Python) and
cocked it for each plate. I downed all of them, but my
happiness was shattered by a taunting voice of a 1911 partisan that
said "hey, Grant, I've got a gun that does all that for me!"
After that I removed the SA from my revolvers and started shooting
DA exclusively. It wasn't long before I was beating the guys
(including the loudmouth in question) who were shooting 1911s with
crisp single action triggers. It can be done!
If you have any doubt as to how accurately a double action can be
shot, go watch your local PPC match - there's one just about
everywhere in the country. You'll see lots of folks shooting DAO
revolvers at up to 50 yards and producing groups that can be
covered by your hand. That should be good enough for any defensive
use, and you too can do it with just a bit of practice!
