I am a new owner of my first Sig Sauer. I just bought a sp2022 at a gun show. It was used and I have no way of contacting the seller. I have spent HOURS on YouTube and online to little avail. I'm hoping someone on here can help. My sp2022 has only a Double Action trigger pull and no decocker. It has a space for the decocker but no decocking lever. I have a place I can purchase a decocking lever and decocking spring but I don't know if I need anything else in order to restore my Single Action after the initial Double Action Pull. Any one out there that can help a brotha out? Lol!
