Took the right grip panel off last night and as pics show no numbers under it or on the left side as well. The serial number is stamped on the bottom by the laynard ring, barrel and cylinder and all match. As the pics show too there is no type of US markings on the top strap either. Is this one of those that were not marked? Looking in blue book it states that some did not have any US markings on them. Just trying my best to see if I was taken to the cleaners or not. Thanks again to all those who have replied so far. The information is very informative for this beginner.
