Diamondback Firearms DB9FS 9mm Luger, $265

Read Gun Tests Rating and Recommendation

Attention to detail was lacking, in our view. The sights were not well regulated from the factory. We fixed that, but suffered a short cycle that we did not experience with the other pistol. Accuracy was poor. The magazines were difficult to load.

The Diamondback fields-strips easily. Fit was not tight. The takedown resembles that of a Glock, with two levers on the frame that are depressed to remove the slide. When we field-stripped it, the recoil rod and spring easily fell out of the slide.
Fired from a braced position, the Diamondback was comfortable to shoot. It just wasn’t as accurate as the TP9SA. The slight cutout under the trigger guard helps the pistol sit lower in the hand.
The only malfunction during the test was a failure to eject with the Diamondback. The Diamondback 9mm proved to be the better performer during combat drills, our shooters said.
