I bought the gun privately. I just did a close comparison between the 2 guns. Under magnification of the straight grip, I can see no indication where new checkering was cut and blended into the existing checkering. The diamonds start at the top and go into a continual smooth uninterrupted flow to the bottom. The checkering pattern is also not the same design as the pistol grip gun. The checkering on the straight grip starts further ahead of the safety button and flows further back from where the pistol grip checkering starts its downward curve. To have altered the existing checkering they would have had to sand away and remove the checkering and border. The width of the wrist measures the same on both guns kind of indicating no sanding was done. But I will never say never. Even if the checkering/stock is original, there is nothing to say that some previous owner didn't have the trigger guard electroplated.
