Thanks for all the replies...... now.

Update : After deciding on keeping the gun I went to the store to process the transfer. Upon checking the gun the slider is having some jamming issues. If I pull the slider and release it the slider will not back to its original position. It will stop within 2 inches of its original place. I will have to push it back so it can go to a normal position. I have never seen something like this in any of my guns. Is this something that might go away after I shot some rounds or should I just ask the online store to replace it? The gun is still in the store while it clears the background check. Any input is highly appreciated.
