I have looked at a couple 4" sts pythons and both of them seem to have fitment with the side plate. The gaps seem larger and the bottom portion of the plates almost seem to have been forced in. My 6" sts does not exhibit this, nor do any of my blued pythons. Is this pretty standard for an 80's sts gun, or a sign that they have seen better days? BTW this is the only place on both of these pistols that looks "off", the remainder of both revolvers looked immaculant.
