My girlfriend picked up my camera bag with it being unzipped. My Sigma 18-50 ex dc came spilling out about 2' above the table the bag was on. It had the lens hood attached backwards and both front and rear caps on. The lens hood and front cap popped off on impact and I heard the THUD from the other room. 


After inspecting it I can not find any visible damage, no broken glass thankfully. There is a little ding on the hood, but oh well. What scares me though is when I extend the lens to 50mm and wiggle the front barrel I get a little play, I am not sure this was there before because I never checked, maybe someone that owns one could help me out on that?
I put the lens on my camera and it does focus fine and takes a picture. I looked at a few test shots on my computer and it seems sharp still. This lens was really sharp before, so I am going to do a real focus chart test tonight (fingers crossed).
So my question is should I send this in to Sigma just to be sure nothing got knocked out of alignment? Is the play in the front barrel I am feeling normal? I bought this lens a month ago for a upcoming trip to Mexico and I don't want to find out later on that it has a problem.
Thanks for the any help.
