I ordered this from IRUNGUNS. $229 USD was just too good an offer to refuse.
https://www.irunguns.us/product.php?p=diamond-back-firearms-db9fs-9mm-4-75

It is made in USA (Coco Florida) by a company better known for making cheap pocket pistols.
The transaction went very smoothly. I ordered on IRUNGUNS website and within a week had the pistol. It comes in a nice little hard plastic gun case, with a simple owner’s manual (with full colour pictures). The warranty is void with +P loads or handloads. For $300 CDN, who cares?

It comes with only 1 mag. That is annoying. The good news is that the mag is a modified Beretta M9 mag, so military surplus ones are available for less than $15USD. I ordered 4 more. To work in this pistol, and extra notch is cut in the Beretta mag, much the same as we modify a CZ mag to work in a Grand Power.

The mag supplied is a pinned 15 shot military surplus Check-Mate mag. It only holds 9 rounds. I will have to re-pin it.

The grip is comfortable in my largish hands. No adjustments are available. For me, it is more comfortable than a Glock but not as comfortable as a M&P9. I added a small strip of skateboard tape to the front and rear of the grip. I do this to most pistols. The magwell is flared a bit, so inserting a mag is fast and easy.

The mag release is easy to use and the mag drops free.

The black stainless steel slide looks like a Glock, with better sights. The slide has sharp serrations, front and back, for racking the slide. The rear sight is a Novack style steel unit that sits in a dovetail. It is anchored with a small Allen screw. The rear sight notch is wide, giving lots of clearance on either side of the front sight. This makes for fast aiming. I really like the sight picture. Much better than the stock Glock or M&P.

The barrel to slide fit is tight, as is the slide to frame fit. Much better than I expected.

The trigger is fair. Better than M&P, not quite as good as Glock. Feels to be around 6 pounds. I will polish the key parts. Reset is fairly long.

It does not have a mag safety. Yea!!

The slide release is a bit heavy. I won’t use it. It reliably locks back on an empty mag.

Barrel is a bit longer than Glock or M&P – about 4.75”. Sight radius is about 6”. Barrel has conventional rifling, so lead bullets should not be an issue.

Take down is pure Glock. The frame feels incredibly light. I can’t help but wonder how strong it is. I won’t drive a truck over it to find out.

Features
Rail on bottom of frame for a light or laser. Steel, not plastic rear sight. Drop free mags. Cocked indicator (small protruding pin at rear of slide). Peep hole to see if a round is in chamber. It only weighs 1.5 pounds.

Shooting
I took slide off and it looked to be almost dry inside (opposite of a Norinco) so I lubed with a few dabs of CLP.

I cant a handgun slightly, so it will group left unless I adjust the sights. So before going to the range, I adjusted the rear sight about 3mms left. Groups were on paper, so I was able to test it for grouping ability with three power levels of ammo. I shot at a fairly fast pace at 20 yards. One shot every 5 seconds. It grouped well.

That is the good news. The bad news is that I was aiming at the target above the one I hit. It shoots 5” low. My M&Ps, out of the box, also hit low, so I had to replace the front sights.

Conclusion
A great gun for the price. It cost me $300 Cdn, plus shipping. I can’t really compare it to anything, because no other 9mm costs so little, except maybe a Norinco Tokarev – which it out performs.

If you need a cheap 9mm of some purpose – this is a good bet. If you need a cheap 9mm for CQB, IDPA or IPSC, this will work just fine. I like the fact that it uses cheap and readily available surplus Beretta mags. Some off brand pistols use proprietary mags that are expensive or difficult to source.
My only complaint is the trigger. It is better than my M&P – but it got an Apex treatment and is now superb. This trigger will get polished and should then go from Fair to Good. The rear sight will have to be replaced with a taller one. I might have something in my parts drawer that will fit.

I had issues with mine when using S&B ammo, getting crescent-shaped shards into the striker channel and firing pin stop compartment leading to light strikes. These issues were corrected by using PMC ammo. This was discussed previously in the original product thread.

I find the squishy trigger hard to adapt to. I do like the pistol and hope to like it even more when I get better used to that trigger. Never fired a striker-fired pistol before. Mine has the "old" slide with a dovetail front sight whereas the later models apparently had a "Glock-type" front sight. The pistol is a comfortable one to hold.

I bought a 4 pack of mags from IRG afterwards. These mags have a stiffer spring so cutting a loop or two off is on my to-do list.

Some good discussions on diamondbackforum . com
 
I need a taller rear sight. I knocked out the factory rear and found it uses the Glock dovetail. As it happens, I have a spare Glock rear sight and it fits perfectly.

I might have to get an even taller one. About $8.00 USD on ebay. Or a fully adjustable one for about $27. That is what I have on my Glock.

When I get a new gun I try a series of loads in it, running from START to MAX, to see what it prefers.

I knocked out the factory sight and installed a Glock rear sight. The 7.3mm one, the tallest they make. This turns out to be perfect for my pistol. The factory sight was hitting about 5" low.

The trigger is good for fast shooting, where you pull the trigger all the way for the shot. It is not so good for target shooting, although it does hang up just before the break.

I fired about 50 shots today. Two did not fire on the first attempt, but did fire on the second try. This ammo is loaded with Tula primers. They are hard. I will try a batch of ammo made with Winchester or CCI primers.

I have a lot of 9mm pistols, so I make and stockpile ammo loaded with the DRG lead round nose of 135gr. This has been an accurate bullet in everything. I use TiteGroup with lead bullets. I load 3.1, 3.3, 3.5 & 3.9.

3.1 is very mild. It won't cycle some guns. It ran ok in this pistol, but 3.3 was the clear favourite. It puked with 3.9.

I am showing both the 3.3 and the 3.9 to emphasis once again why it pays to try a variety of loads, to see what a gun likes. There is usually a clear preference.

20 yards - 2 hands

That's a remarkable difference, not reloading myself I had no idea .3 grains would make such a difference. Are loads of different powders also as crucial? (you said you're using Titegroup here)

That difference is 0.6gr, which is a significant difference with TiteGroup. The accuracy difference in this case is the biggest I have ever seen, but every gun so far has shown a favourite loads and loads that were NG.

Handloaders often try to make the hottest ammo they can, and thus miss the accuracy potential that can be found by trying a range of loads.
 
I took mine out not long ago. Shot alright bit left and down.
Some one sure went to town on polishing the crap out of the feed ramp it looks like a mirror.
I shot basic Federal and American Eagle with no issues. I am now a little worried loading for this thing.
 
Interesting review, thank you.

Could someone post a picture of the gun field stripped?

Thanks

If it shoots left, move the rear sight right, or the front sight to the left. It moves very easy one you back off the allen screw. Make a witness mark, before you move it, so you can see the movement. Try about 2 mm.

If it shoots low, buy a 7.3 mm Glock rear sight on ebay. About $10

Why would you worry about loading for it? It is an plain 9mm with conventional rifling. easy peasy to load for.
