I was shooting my P7 today. I have kept it pretty clean and well serviced. I put about 75 rounds of Wolf/Blazer through it with no problem. Then I had some left-over Aguila IQ bullets and decided to try them as my wife wants to carry the gun. I only had 4 or 5 left. Every round was a failure to eject or feed or stovepipe. OK, no problem. I'll use them up and thats the end of them. On the last round I tried opening the slide and it is stuck. Tight. Now what? THanks.
