Questions & Answers
Is there a way to get the bolt catch shown in the second picture? I want the one that has the extended bottom. Is there a part number for this one? Expert Answer

Unfortunately Sig has not provided a part number for that item and do not seem to be selling it separately at this time. We recommend contacting them directly, they may still be able to provide that part. You can reach them here: https://www.sigsauer.com/company/contact/
