Question - I just fired my new P226 9mm today for the first time. I ran about a dozen mags through it. It shoots great. I love it. However, the slide actually stayed open after the last shot only a couple of times. I would go to fire the next shot and it would dry fire. I opened the slide to see it empty. After the first couple of times I think I could actually feel the difference when it would slide forward without pushing a cartridge into the chamber. I didn't do a full cleaning of the gun before I fired it the first time but didn't think it would make much of a difference. I was shooting cheap ammo too, but don't think that should matter for this problem either. It wasn't like it was having FTF or jamming stovepipes. I was shooting Remington UMC 115 gr. FMJ. Any ideas? I am going to clean it good and try again as soon as possible but it will be at least a week or more before I can get back to the range. Are there any other factors which could cause this? Should I take it somewhere to have it checked out?
