I have a collection of various model 945 variations, and I'm trying to decide which of these two duplicates to keep. They are essentially identical 945-1 compact, 3.25" models, with serial numbers only a few digits apart (RSC00xx & RSC00xx). One, however, has a ported slide and barrel, and there is my question: Does anyone know if the porting is factory original, or an aftermarket job? I've never seen any other ported 945's, but you never know. I don't want to keep it if its an aftermarket mod. Thanks for any insights.
