My boyfriend bought me a Walther PK380 about a month and a half ago. It worked well the first 300 rounds then a sight fell out, it kept getting jammed, and the extractor broke. After this happened I could not pull the slide back. The dealer sent it off to Walther and I got it back two weeks later. After getting it fixed and putting 200 rounds through it the gun isn't as accurate as before and once again I can't pull the slide back. My boyfriend owns a Desert Eagle and said the slide on the PK380 is currently just about as hard to pull back as the DE. He wants me to check out other guns and I have no idea where to start...again. Any suggestions?
