Well - I took the DB380 out today with two boxes of Aguila 380, one box of Winchester white box 380, and about 15 loose rounds of 15 year old Federal Hydroshock (plus two rounds of Winchester Silver Tip). I started with the Aguila. Mag after mag with no malfunctions. Moved on to the Winchester white box. All fifty without a single malfunction. At 15 yards, I was getting 4 inch +- groups a little to the left and slightly low. After drifting the sight to the right, windage was right on. I saved the last few Aguila rounds and moved to the Federal HS. It didn't chamber well. It tried to hang up unless I jiggled the slide a little and rode it closed. The good news is that once it chambered on the HS, it fired then cycled the next HS round without fail. I shot all of the Hydroshock without other malfunction beyond being hard to initially chamber. Next - the two Silver Tips... Click... Nothing. They chambered fine, but had what appeared to be light primer strikes - no boom..... I tried each one twice, then threw them away. I think some Winchester primers are a bit hard. I'll chalk this up to using some ancient hollow point ammo that I've had forever. I didn't have any other defensive type rounds. When I find some for sale, I'll buy them. But the local stores don't have much of ANY .380, especially hollow point. Going back to the Aguila - perfect... Every round barring the Silver Tip fired and cycled the action perfectly. Even the finicky old-style Hydroshock worked every time once I got the first round into the chamber. This gun is going to be a big seller I think. It is made very well. I think the Kahr has been the most refined pocket pistol in recent history and the Diamondback is right up there in quality, fit and finish. I have owned or shot most of the other players out there, Kel-Tec, Ruger, NAA, etc. Diamondback and Kahr are the two to beat in my opinion. Once I get some modern defensive HP through the DB, I'll update this report. It might take a while. In the meantime, I'll stick with the PM9 as I usually plan to do anyway. The DB is for those really HOT summer days or when other factors dictate the need for a really small gun.
