A Diamondback with a Bite – The DIAMONDBACK 380

When I first spotted the DIAMONDBACK 380 at the range, I had to handle it. Wow! Talk about a pocket-pistol!

I had never heard of it and some subsequent research found the company on the WWW and a review by Jeff Quinn at Gun Blast plus many other informal reviews found on YouTube and various firearms-related sites.

Usually lagging behind in the review curve, I thought that I would throw my two-cents into the pot and share with you my impression of the “Diamondback with a Bite”.

Features and Specifications:

Type: Pistol Action : Double Action Caliber : 380 Automatic Colt Pistol (ACP) Barrel Length : 2.80 Capacity : 6 + 1 Safety : Firing Pin Block Grips : Black Synthetic Sights : Adjustable Weight : 8.8 oz Finish : Black. The DB380 features a ZERO-Energy striker firing system (patent pending) with a mechanical firing pin block, a steel magazine catch to secure a sheet metal magazine and real windage-adjustable sights, all in a lightweight pistol. It has a steel trigger with dual connecting bars.

Weight: 10.1 ounces Height 3.76″ Length 5.25″ Slide Width 0.758″ Maximum Grip Width 0.74″ Frame Width 0.748″ Maximum Width 0.76″ Barrel Length 2.79″ Trigger Pull 4.5 pounds Magazine Capacity 6+1


As you can see in the picture, the DIAMONDBACK 380 lays in the palm of my mitt quite well. I normally do not like shooting guns where the barrel is shorter than my fingers. However, rule exceptions are part of life. My curiosity was running wild and I was not going to pass this opportunity up.

First of all, and although I don’t like comparing one gun to another, the DIAMONDBACK 380 looks like mini-mini Glock and there are several versions of the DIAMONDBACK 380

  1. Diamondback DB380
  2. Diamondback DB380EXO
  3. Diamondback DB380C
  4. DB380HO Diamondback (colored frame)
  5. DB380CTC (Laser)

The version that I would be testing was the DIAMONDBACK DB380.

Picking up the pistol from the counter I dropped it in my shirt pocket, grabbed my target, donned my “ears”, and went into the range to my assigned firing lane. Lord, I thought! I have had cell phones bigger than this.

The Frame, Fit, and Finish:

The frame is of a slide Glass reinforced polymer material and is finished nicely. The Assembly Catch is the only control that exists on the frame aside from the magazine release button. Making sure that the pistol is safe and removing the magazine sets up the gun for take-down. Pulling the slide slightly to the rear and depressing both Assembly Catch serrations releases the slide from the frame. This is the same procedure as is used on quite a few striker-fired pistols.

The fit of the slide assembly to the frame is excellent. The finish on this particular is matte but the type is unknown but looks very closely like that used on Glock pistols.

The trigger housing has a design different from most, as it is rectangular and does not leave much room to fit a gloved finger but it a gloved finger will fit.

The front of the trigger housing contains horizontal serrations and is squared off with a slight lip to accommodate the trigger finger of the support hand (also needed when pulling the slide rearward to help support the gun during a loading check or when pulling the slide to the rear)

The trigger’s pull weight on this particular model was right at six pounds (compared to the manufacturer’s spec of 5 pounds) and was smooth throughout the pull. The take-up was about 0.10 inches until feeling resistance. The pull distance from resistance-to-fire was about 0.40 inches. I could not detect a reset point. There is one quirk with this trigger and I will cover that in the Range Fire portion of this write-up. The trigger has dual connecting bars ensure a smooth pull.

The sides and front of the grip area are nicely stippled.

The magazine release button is a little it of a thing but responds nicely when pressed firmly to release the magazine. Located just behind the trigger guard, pressing the Magazine release button requires a change in grip or pushing it with the thumb of the support hand (right-handed fire). The magazine release button is not ambidextrous, is made of steel, and is out of the way when firing.

The magazine was of metal and held a low-friction magazine follower. Loading the magazine without assistance was easy; so easy that I felt like I was pushing a bullet through butter at room temperature until the last round where I felt some resistance. I felt no sharp edges and the base plate is of polymer with no “pinky Lip”. You can let the pinky stay off the gun or wrap it under the magazine.

The slide Assembly:

A large dot adorns the fixed front sight and the drift-adjustable twin-dot rear sight provides the remaining sight alignment needs. The sights are easy to align. With this particular model, a green dot for the front sight and white dots adorn the rear sight.

The slide does not lock back on the last round and the double-recoil spring arrangement helps to soak up all of that mighty recoil generated in such a small pistol. The double-recoil spring arrangement also takes a little effort to pull back on the slide. The slide is nicely serrated front and rear to accommodate a safety check and to chamber a round for firing for the first time.

Range Fire:

I hung the B-27(24) REV RC – 50-Yard target on the frame and moved it to my usual 7-yard line for testing. I was using Remington’s 95 grain MC round for this test and had no idea where the rounds might punch through on the target so I wanted to give myself as much space to play with as possible.

I was firing slow, two-handed, and unsupported, as this gun is just too small to bench rest. Most of all, I hoped that my aging eyes would pick up the sights and put them where they needed to be.

Aligning the sights for a 6 o’clock picture, I started to squeeze the trigger. Then, it seemed, as though I had hit a brick wall. The travel through the resistance just seemed to stop. I backed off the trigger and unloaded the weapon. Sliding an empty magazine into place, I attempted to dry-fire the weapon. At the very end of the pull, there was a tremendous amount of resistance. It took some effort to get past in order to release the striker. I did not detect this during the trigger pull test but, then again, I was using a trigger pull gage.

I re-loaded the magazine, slid it into place, pulled the slide back and let it go into battery. Refreshing my sight picture, I worked past the resistance and the first round struck the target low and left of center. I shifted the sight picture up until the dots lined up with the center of the X-ring. This time the second round went through the target almost centered but slightly left. Raising my sight to the top of the X-ring put the third round slightly above the 5X in the 5X circle but still slightly left.


I loaded a fresh magazine now knowing about where to place the sights. Shooting left could be the sights or me but, since this was a range gun, I would just have to compensate.

The picture below right is the result of 18 rounds of fire with moving the sight picture slightly right and placing the dots at the top of the X-ring. Most went in the 5X with a few stragglers. The result is not bad for a gun this size!

Recoil is mild and muzzle flip easily controlled with the index finger of the support hand surrounding the trigger guard. Even with that, this gun has to firmly held and with authority – and, to me, there is not much to grip.

After twelve rounds fired, and even with me holding the front of the trigger guard, my trigger finger of the shooting hand took a beating. With pocket pistols of this nature, this is a common occurrence in my hands.

After the test was over, I ran two magazines fast-fired. The gun is quite capable of putting rounds where you need them to go and in a relatively confined space at short distances. A solid shooting platform is necessary and I would advise two-handed shooting. In other words, shoot it as if you mean it.

While carrying this pocket pistol might invoke pathos in some toward those who carry it do not let its diminutive size deter you from pocketing this pistol in your favorite pants, vest, or shirt pocket (holstered, of course)

The Diamondback rattlesnake is both dangerous and deadly and the DIAMONDBACK 380 has the capability of making the user of this device just as dangerous and just as deadly to a threat. This small package can pack a punch with the best of them.

The DIAMONDBACK 380 is not a target pistol. The DIAMONDBACK 380, intended for personal defense, will fill that roll nicely.

Diamondback Firearms also recently released the DB9, a micro-compact 9mm automatic pistol made entirely in the USA. I would like to get my hands on one for testing.

This was a very complete testing of great quality. I have wondered about the Diamondback for some time.
Thank you for a great article.


When will you testing the other model 9MM ?


As soon as I can get my hands on one, yes.


Read the whole article to find out why you decided to wrap tape around the frame, with no joy.  DOn’t leave us hanging.


The firearm that I was testing is a range rental. The range wraps red tape around all of their range guns for identification. In fact, and with the exception of those that I own, all guns that I test are available to me at the range where I am a member. Until major manufacturers start sending their guns to me for testing I will, unfortunately, have to do a “Poor Man’s Review”.


Do you feel night sights are necessary for such a small pistol as the DB380?


I’ll put it this way; it certainty can’t hurt. Anything that can enhance the aiming of a firearm, in my view, is a plus. I did not find a problem using the standard sights, as they are easy to pick up. For myself, I would probably invest in a Handall Jr. slip-on grip sleeve rather than the night sights. Even with the Handall Jr, grip sleeve, some surgery on the grip might be required to fit the small grip of the pistol. That is; however, speculation on my part.


On the trigger pull, I did the exact same thing with my Kel-Tec P-3AT .380. When I took it to the range to fire, I started slowly pulling back on the trigger. It seemed to get heavy about half way back and the gun still had not fired. I thought something was wrong with it and also did the unloading thing and dry firing. Put the mag back in and this time continued the trigger pull. It fired and was very accurate for such a small pocket pistol. Glad I spent some time with this pistol. Had I not, it would have freaked me out in a real situation. My Glock 19 and Star PD45 fire with way less trigger pull. Maybe this is a safety feature so you don’t shoot youself pulling it out of a pocket!!


did want this until i saw the failure to reset the trigger!! that could cost u ur life


I’d like to get one for myself and my wife, but no dealers in New York state. We have a place in Fla not far from their headquarters. Does anyone know if I can purchase there with a NY permit and either ship or bring it back?


I’ve been trying to get a brand new db380 to fire six rounds without a malfunction for several weeks now and its just not happening. It is a piece of junk.

I want to give you a little bit of a warning concerning this gun. On December 18, 2012, I purchased a DB 380 and really loved it. It was quite accurate, etc. But, after getting about 200 rounds through it, it started malfunctioning badly — jamming; failure to eject; even fed two bullets at a time. The guys at the shooting range where I purchased the gun cleaned it, just to make sure. It still malfunctioned — for them as well as for me. So, they sent it back to Diamondback. After 4 weeks, Diamondback returned the gun, telling them that the ejector had to be replaced and that they had put 18 rounds through it, and it was fixed. The guys at the shooting range tried it out before even telling me it had come in — it was NOT fixed at ALL. It was still malfunctioning just as it had before it was sent back to Diamondback. They video-taped how it was malfunctioning; contacted Diamondback and sent the video to them.

Diamondback did NOT respond back to them and has STILL not responded back to them as of today. I can understand that something can happen to a gun, etc. But, for it to be sent back to the manufacturer who “fixes” the gun and sends it back saying it’s fixed and is working when it’s not is a TOTALLY different story. My very strong impression is that Diamondback will NOT stand behind its products. So BEWARE!!!
In the meantime, I have purchased a Sig P238 — works wonderfully!!!


Was thinking about getting the Diamond Back. Sounds like the trigger action on the Kel Tec 380. Kel Tec is an awesome gun, but the trigger action is murder on the trigger finger. Even though these pistols are for defensive purposes, you still have to practice with it, and that trigger action is awful on the trigger finger. But if you got a fat finger, maybe you will be okay.


thank god i did not have to us this piece of junk ,for self defance!,i would have lost the battle. call the diamond back co. adn they told me i had to run 100 rounds with cci ammo ect.well ran 200 rounds and still ant worth shit,just jams up!!!!!!!!
