On Thanksgiving I went out and had my first range session with my new DB .380. I was shooting aa RWS 95gr .380 ACP cartridge. I put 6 rounds thru the gun and has some serious issues. I had two stove pipe and three where the casing didn't even eject. I thought maybe it was a break in period. I continued to put several rounds thru and continued to have the same issues, the slide actually separated from the receiver. This made me really nervous and I packed the gun away til I could find more answers. I have the ZB model. I thought maybe it was a cheap cartridge. My grip was nice and tight on the grip. Just not sure what to do. Sell it? Try a different cartridge? Send it vack to the manufacturer? Help please.
