Purchased, mine in Dec and have had similar, it has gotten smoother with round count hitting 1,000, also used flitz and dremal to polish, just noticed one side of the rail the serrations are cut into the slide rail,, meaning the serrations on the front of the slide carry down onto rail, but not on the other side....all part of the charm, bottom line .....these are not 1,500 dollar guns, but they shoot like they are.....
