Hello, I am looking for an Internal Extractor part #872370A for my Stainless Steel Sig P220 ST 45 ACP . The picture provided from my stainless slide that is circled in red is the type of extractor I need. The picture of the part included in this message shows the extractor circled in red with your part showing the difference between the two extractors shown. The orientation of the tang circled is what makes the difference and would allow it to fit into my stainless steel slide . I can be reached at 732 277 4827 Dino . Thanks for your time .
