After reading yours and others comments on the loose slide and trigger noise I had to check mine. I've had over 500 rounds through mine and the slide is still tight and so is the trigger. I can make the trigger move if I grab it and push it back and forth, but it doesn't move on it's own or does it make any noise when I shake the gun vigorously. When I grab the slide in any condition I might get it to move up and down 1/64" if that. Slides are made to go back and forth not up and down, and from everything I've heard and read this play is normal for a 1911 after break in. You want to see play in a slide check out a Springfield XD. I have two of them in different sizes with thousands of rounds through them and they have better accuracy than the 1911. When my Sr1911 is in battery it is very tight after hundreds of rounds, so I don't know if you guys have a problem or not. Probably not, but if it's going to bother you, take it to a gunsmith and have him check it out. If you do don't tell him what you think is wrong with it. Just tell him you want to have it checked out for safety.
