I bought a NIB Diamondback DB380 yesterday along with 50 rounds of Magtech 95gr FMJs. I took it out to shoot today along with 2 mags worth of PMC 90gr and a few Winchester rounds that I don't know the weight of but were flat nosed rounds. My first two mags worth of Magtechs had a failure to feed on about the 3rd or 4th round out of the mag where it looked like it was feeding high. The base of the round was still on the top of the lower round in the mag and the nose was sitting high (Wish I had taken pics). After about 3 mags of the Magtech with the 3rd mag firing without issue I loaded up the PMCs and halfway through the mag the pistol failed to fire. I could pull the trigger and nothing happened. Racked the slide and still nothing. I came back up to the house since I could not disassemble the pistol without a dental pick. I used a hooked pick to reach inside the pistol from the rear to move the sear under the striker to get the slide off the pistol. After looking over the pistol for a bit and seeing that raising up on the right side transfer bar would allow the sear to move I saw that my problem was the sear spring was sitting on the back of the transfer bar. Looking into it even more I saw that the spring had come out of the groove in the back of the frame. Here are the pics of what it should look like and what I had going wrong. Spring in the correct position: Another of how the spring should be sitting: Here is what my spring looked like when it malfunctioned: As you can see the spring came out of its channel and was causing the transfer bar to be unable to contact the bottom of the sear. After fixing the spring issue we went back out and fired the remaining ammo that I had along with some Independence ammo of a friends. Had some more feeding issues that got better over the course of shooting and once it looked like either my friend released the trigger too soon which kept the firing pin from resetting or it may have short stroked on the independence ammo and not reset the firing pin causing the round to jam on the protruding firing pin. I did fire off quite a few mags worth without a single issue at the end of my shooting session as well as a few rapid firings without a hitch. Accuracy was very good out of this little pistol at the 7-12 yards we were shooting at. It never failed to fire a round when the trigger was working. Shooting it is much nicer than my friends LCP which we shot in comparison and which also had a few feeding issues which made me feel not so bad... All I did before shooting was to give it a good cleaning, light oiling and greased the rails and contact points with Pro-gold grease. I did not clean the mag before shooting. I really like the feel of this little pistol. I wanted something small to carry and never liked the feel or shooting of the LCP or Kel-tec. Something I did notice after carrying it around a bit is that the rear of the slide has some rather sharp edges that let you know they are there from time to time. I will be calling Diamondback on Monday to discuss my issues and see what they say. I knew before buying that there were some with issues but am willing to take a chance and if it has to go back home for a visit I am OK with that. I did ask for the highest serial number the shop I went to had which was a ZA28XX. I will keep this updated with my response from Diamondback as well as further range reports when time and ammo permitting it can be done. I would say it is about 70 round into the recommended 200 round break-in so I am not really going to complain about the jams but the spring thing is an issue. I just wanted to post what I found out about the spring for others who may have the same issue.
