Picked mine up today.
Won't get to shoot it for a couple of days or so, unless I can find a little window of time to duck off to the range and blow off a couple of boxes of ammo.
But I did get a chance to disassemble it and give it a good dose of Ballistol. I'll let it soak overnight before wiping it down and lubing the rails.
First impressions: this gun looks and feels to be much higher quality than the price would indicate. I own a couple of KelTecs, which are similarly small, cheap, and light polymer guns. But the difference is that they look and feel cheap, too. But the DB9 has no obvious machining flaws or flaking polymer. It has great sights right out of the box, and the trigger is amazing for a little micro gun.
Fingers crossed that it shoots as well as it looks/feels. Range report to follow....
