Took this out for a full day of shooting in Grand Prairie last month. Even in 95-degree weather, the DB15 ran without a single malfunction. The short barrel with the stabilizing brace made it maneuverable in brushy areas.

Used it for three range trips now. The 5.56mm pistol handled premium rounds perfectly, but I had a couple failures with budget steel-case ammo. The brace system is comfortable and stable for quick shots.

The compact size with the Maxim brace makes this ideal for home defense. Tested it with different 5.56mm loads and found it consistently accurate at indoor range distances. Dallas Shooters Supply provided excellent service on this Texas-made firearm.

Shot about 200 rounds through it at my local range. The 5.56mm performed well with various ammo brands, though the trigger pull felt heavier than I expected. Still a solid purchase for the price.

Took it to the range in Fort Worth last weekend and was impressed with the accuracy at 50 yards. The 5.56mm rounds cycled flawlessly, and the Maxim brace made it easy to handle in tight spaces.

Zeroed the iron sights at 25 yards and was hitting consistent groups. The pistol balanced well with the Maxim brace, making it comfortable to shoot for extended sessions. Dallas Shooters Supply had it ready to go.
