20 POLICE DECEMBER 2016
There are few moments in history that
drastically change the direction of
American law enforcement. As a
rule, police agencies are measured and
methodical about changes with most tak-
ing place at a glacial pace. One such dras-
tic event occurred on Feb. 28, 1997.
On that day dispatch received traffic
from an LAPD patrol unit calling for as-
sistance with a "211 in progress." It was
quickly followed by "Shots Fired–Require
Backup." This call would forever change
the law enforcement weapons culture. It
was the beginning of the infamous North
Hollywood Bank Robbery shootout where
the LAPD ended up engaging two heavily
armed suspects determined to avoid cap-
ture after a bank robbery.
The two robbers in that 1997 gun-
fight were armed with fully automatic
rifles while the responding officers were
equipped only with a variety of handguns
This 9mm AR-style rifle features a built-in suppressor and was designed specifically for law enforcement operations.

and the rare shotgun. The two suspects
were not only heavily armed, but they also
wore body armor, which the police stood
little chance of defeating with handguns.
This situation eventually drove several of-
ficers to enter a local gun store where they
secured rifles to engage the suspects. The
fight continued until SWAT arrived and
the suspects were stopped.
In the end there were more than 2,000
rounds fired by both sides, resulting in 18
casualties and two fatalities. This was one
of the longest and bloodiest shootouts in
American law enforcement history. The
incident would change the law enforce-
ment community's view on rifles and the
need to include rifles in patrol cars.
In the years after North Hollywood, the
AR-15 rifle became the "go-to" long gun
for law enforcement. The AR is light, easy
to shoot, and relatively inexpensive. Ad-
ditionally, many officers across the coun-
try had prior military service and were
already familiar with how to operate the
AR-15 platform.
Today, the AR-15 and some AR-15
variants remain the most popular law
enforcement patrol rifles. But there are
alternatives. One alternative patrol rifle
platform that recently came to my atten-
tion is the D3-9SD rifle from Desert De-
sign and Development.
DESIGNED FOR DUTY
Desert Design has dubbed the D3-9SD
the "ultimate urban carbine." It is an inte-
grally suppressed short-barreled rifle built
on an AR platform that's primarily cham-
bered for 9mm. The engineers at Desert
Design have created a suppressor unit that
shrouds and integrates with the barrel,
which creates an especially quiet weapon.

DESERT DESIGN AND DEVELOPMENT
D3-9SD CARBINE
The Desert Design and Development D3-9SD is a pistol caliber carbine with
a built-in suppressor.
SHOOTING THE DESERT DESIGN AND DEVELOPMENT D3-9SD CARBINE
22 POLICE DECEMBER 2016
The major upside to the continuing
popularity of the AR platform is its famil-
iarity of operation and ease-of-use by just
about anyone in American law enforce-
ment. The learning curve to using this
weapon is almost non-existent, as the
manual of arms is based on the standard
AR-15. An additional bonus feature of the
D3-9SD is the fact that it runs on standard
Glock-style magazines.
This shows vision from the designers
who wanted their new carbine to appeal
to police. Glock handguns are by far the
most popular pistol carried by law en-
forcement across the country.
This carbine is designed to
complement officers' exist-
ing Glock handguns and give
them the tactical advantage of carrying
only one caliber of magazine that they
share between their pistol and carbine.
The ability to customize that AR-15 us-
ers enjoy carries over to the D3-9SD as
well. The weapon is designed to allow for
standard AR drop-in triggers and after-
market safeties in any other AR design
furniture on the market.
Overall length of the D3-9SD gun rang-
es from 23 inches to 29 inches, depending
on the stock. The unique lower is milled
from 7075 billet aluminum and is dedi-
cated to the Glock-style magazine. While
some companies insert blocks into the
magazine well to make this happen, the
D3 gun is a dedicated weapon. It is billet
machined and hard coat anodized for the
finish. Desert Design is also in the process
of developing an even shorter "K" ver-
sion. The D3-9SD's barrel with suppressor
length is only 14 inches, which makes it a
nice small package for carry and use.
While the D3-9SD was built as an AR-
style weapon, the designers have includ-
ed an enhanced bolt carrier as well as a
9mm specific brass deflector. The D3-9SD
has a 9-inch forend with a choice of key
mod or a quad rail. While small, it allows
users to mount critical items like lights.
The gun is finished out with a Magpul
K2 grip and MOE stock. While primarily
chambered in 9mm, Desert Design will
also have models set up to run 40 S&W
and .45 ACP as well as 10mm for the more
adventurous among us.
The entire carbine tips the scales at just
over seven pounds, which is close to the
standard weight of a full-sized M4 rifle.
Some may question the weight, but it is
important to remember that this in-
cludes the suppressor. This is a very
manageable weight that not only
The gun I received was chambered in
9mm and was a select-fire version. First
impressions of the gun were that it is well
made, lightweight, and the manufacturer
paid a great deal of attention to detail.
Fit and finish of the gun are not an ac-
cident. The designers at D3 understand
that if they're going to make claims of ex-
cellence, as they have, they need to back
them up.
Range testing was enjoyable. First
up was shooting the gun for groups.
While not exactly known for its ac-
curacy, the submachine gun is much

makes it easy to carry, but to manage re-

well as a select fire (full-auto, three-round

OUT ON THE RANGE
Any weapon that is purported to be the
next greatest thing in law enforcement
will have to do some serious convincing
on the range. With that in mind, I set out
to test the D3-9SD.
more capable than most be-
lieve. For this test we utilized
three different types of ammu-
nition, including Remington UMC 9mm
Luger 115-Grain Full Metal Jacket, Aguila
9mm Luger 115-Grain Full Metal Jacket,
and Federal American Eagle 9mm Luger
115-Grain Full Metal Jacket.
Five-shot groups were performed from
a bench with a support bag to rest the
weapon on. This created a very stable
testing platform. Each flavor of ammuni-
tion performed functionally well in the
D3-9SD. The best group we got came from
the Remington ammunition at 1.5 inches.
With the D3-9SD being an integrally
suppressed rifle, the focus kept drifting
toward the actual sound of the gun. D3's
claim of exceptional suppression held
true during my testing. The gun was quiet
even with standard ball ammunition. And
with the introduction of subsonic ammu-
nition, the D3-9SD was almost comically
quiet. I loaded a few magazines with Mag-
tech 9mm Luger Subsonic 147-grain FMJ,
and the gun became the weapon people
in Hollywood put in movies. Already
hearing safe, the introduction of subsonic
ammo produced a dramatic reduction in
muzzle sound.
The last test regarding ammunition
came as I loaded several magazines with

a variety of duty/personal protection am-
munition. While not as quiet as our sub-
sonic ammo, the hollow-point ammuni-
tion was still hearing safe and ran well
with no malfunctions. This in my mind
was one of the more critical tests as the
gun has the option of being a dedicated
duty weapon and reliable function is test
number one.
The shooting bench is not exactly the
native territory for a submachine gun so it
was time to let it off the leash and run it as
intended. This is where the D3-9SD really
began to shine. The gun was comfortable
and easy to run. All of the manipulations
of the gun, including safety operation,
were within easy reach with no change in
position. The trigger on the demo gun was
a standard mil spec version which was a
bit stiff, but that can be quickly remedied
with a new drop in trigger. The cyclic rate
was well balanced and muzzle rise was
negligible. Accuracy opened up as expect-
ed but still remained much better than
other weapons I have fired in this class.
The mix of low recoil 9mm rounds with
a seven-pound gun allowed me to quickly
engage steel at super close-quarter dis-
tance out to 75 yards with no issue what-
soever. The gun gained extra stars when
it came time for reloads. The dedicated
Glock magazine well made it easy to per-
form reloads fast and with little effort. The
overall small size of the weapon made it
feel as if I were reloading a large pistol as
opposed to a rifle. They were fast, smooth,
and allowed me to get back into the fight
with only a momentary break. At the end
of the testing I stood over a pile of brass
impressed with the rifle.
ADD IT TO THE LIST
My take away from this testing is that
there is a real place in the law enforce-
ment community for a rifle chambered
in a pistol caliber. With the advances in
9mm ammunition performance, the ar-
guments of ineffectiveness are null. Un-
derstand that this is not meant to replace a
rifle chambered in 5.56 NATO. There will
always be a need for that insurance policy
should problems need solving at longer
ranges or the bad guys come to the fight
in armor.
This gun is solid at 50 yards and shines
at 25 yards. It would make an excellent ac-
tive shooter response weapon as well as
an entry gun for tactical units. Once again
I reference the ability to use an officer's
own duty mags to keep it fed and a load
out list begins to shrink. Add to this the
fact that it is suppressed and the interest
should be high. The D3-9SD is a good fit
for modern law enforcement. While not a
giant player in the firearms world, Desert
Design and Development has certainly
fired a suppressed shot that I believe will
be heard throughout the industry.
